Biology Research Projects for High School Students

Indigo Research Team

Are you looking for biology-related topics for your high school research project? If yes, then you have come to the right place. 

We do understand that finding the right topic for research that connects with you can be challenging. This is particularly true for the field of biology since it is very diverse. A good biology project needs to have enough scientific research backing it so that it helps support or disprove your hypothesis. 

This article is all about easy and interesting research projects designed just for keen high school students. We'll explore topics in the domain of the human body, ecosystems, diseases and their treatments, and more. 

Biology Project Ideas For High Schoolers

Here's a carefully curated compilation of cool biology topics to inspire and kick-start your creativity. We have broken the list into categories so that it's easier for you to navigate projects that fall into your interest.

Human Body Project Ideas

The human body is said to be the most complicated biological machine, which opens room for good research topics .  Let's check out some exciting project ideas about the human body.

1. Exploring the Rate of Cognitive Decline at Different Elevations

At higher altitudes, there's a reduction in oxygen partial pressure, impacting blood oxygenation and potentially influencing brain function. If you've ever experienced altitude sickness, you've felt the effects of this phenomenon. The decrease in atmospheric pressure at elevated altitudes results in lower partial pressures of gases, including vital oxygen necessary for our bodily functions.

This project can investigate the impact of sudden increased elevation, such as climbing Denali, on brain health and cognition. Additionally, you can also explore whether continuous exposure to high elevations might contribute to an increased risk of dementia. This biology research project can also analyze published studies examining the correlation between altitude and cognitive brain functions. ‍

2. Making a Visual Guide for Blood Vessel Formation

Create an illustration using online images to showcase the process of blood vessel development. In this project, you can search existing research to understand the current knowledge about how blood vessels form and grow. Then, you can use this gathered information to design a graphic explaining how the network of blood vessels, known as vasculature, takes shape.

This is one of the most interesting human biology project ideas that aims to convey scientific concepts visually, making the information more accessible to a broader audience. ‍

3. Exploring Bacterial Communities in Different Homes

If you’re looking for immune system project ideas, this might be it for you. Bacterial microbiomes are groups of bacteria living on or around living things. These communities of tiny cells are essential for our health, helping with digestion and keeping our immune system in check. The microorganisms in our body outnumber our own cells by approximately 10:1. This project mainly focuses on figuring out how the bacteria on our skin differ between people from different households. To execute this biology project, you can create various bacterial media at home and select other microorganisms. 

Note: While conducting research, avoid abrasions, needle sticks, or cuts to avoid getting bacterial infections. Wearing safety goggles, a face mask, or a face shield can help keep you safe. It is also important after the experiments to wash your hands with soap and water and disinfect surfaces that may have been in contact with the bacteria. At the end of your experiment, fully sterilize everything before disposal.

4. Understanding the Control of Biological Clocks

Next up in the human biology project ideas is understanding how biological clocks work. Sleep is managed by two main processes: the circadian clock, which aligns sleep patterns with the day-night cycle, and sleep homeostasis, which tracks sleep debt as a way to recover from sleep loss. 

You've probably heard about the circadian rhythm, our body's internal clock. Circadian sleep regulation is crucial for animals to predict when they should be awake or sleepy each day. These processes can be controlled at different levels, such as genes, proteins, and neurons in the clock. 

This biology research topic can focus on exploring the regulation of circadian clocks at various genetic levels. This project will help you develop important scientific skills in two areas: the first one is learning how to read and summarize information from scientific articles efficiently,  and the second is finding effective ways to present the gathered information. ‍

5. Exploring the Science of Getting Older

Exploring the science of getting older is one of the most groundbreaking human biology research topics. Growing older is the main factor that increases the risk of various diseases like cancer, neurodegenerative conditions, and sensory impairments. Recently, researchers began to unravel the mysteries of ageing and discover ways to slow down or potentially reverse its effects.

What are the signs of ageing? How do scientists study the process of getting older? How do human lifespan and ageing compare to other animals? Can we actually put a halt to or undo the impacts of ageing? What progress has been made in this area? You can delve into these topics for biology projects or brainstorm other inquiries about the biology of ageing.

Animals, Plants, and Nature Project Ideas

Next up, we’ll discuss the biology research projects related to animals, plants, and nature. These environments are very close to human and they are definitely very interesting to explore.

1. Examining the Impact of Genetically Modified Mosquitoes on Disease Rates

In some areas, like the island of Príncipe, many genetically modified mosquitoes are set free every week. These mosquitoes are modified so they can't easily spread diseases like dengue fever, Zika, and malaria. They're released into nature to mix with regular mosquitoes that carry diseases. But only some agree on whether this is a good idea, as there could be unexpected environmental effects. 

You can conduct research on what could be the good and not-so-good things about this. This biology project is about researching articles and videos to understand how and why scientists use these mosquitoes to reduce diseases and to understand exactly how this works. You may even want to explore exactly how scientists create these genetically modified mosquitoes. 

‍ 2. Effectiveness of Ocean-Protected Zones

Ocean-protected zones, known as Marine Protected Areas (MPAs), are specific parts of the sea or coastal waters set aside to conserve marine resources sustainably. Governments, NGOs, or other groups create these areas, and they can vary from entirely off-limits "no-take" zones to zones with controlled fishing or other activities. While MPAs can help manage resources wisely and safeguard biodiversity, there are various reasons why they might need to be revised.

For your marine biology project ideas, investigate the factors that could make MPAs less effective. Then, devise an alternative plan for creating, modeling, and implementing an efficient Marine Protected Area.

For an insightful example of student-led research in this area, explore this project on Applications of Australian Native Aquatic Plants in Purifying Wastewater Sources at Indigo Research . ‍

3. Learning from Nature: Can Animals Provide Solutions?

Exploring the wisdom of the natural world, you can delve into the intriguing question: Can animals offer us innovative solutions to complex problems? How can studying how lizards and newts regrow their limbs help us make wound treatments better or even help someone who is paralyzed from injury to their spinal cord? Why is tilapia skin useful for burns? Explore these new topics in biology on how animals contribute to shaping modern medicine and its future possibilities. 

Also, consider if there are any ethical worries tied to these discoveries and developments. If there are, what are they, and should we be concerned?  ‍

4. Understanding the Impact of Climate Change on the Habitats of Rare Species

Climate change, marked by factors like global warming and prolonged drought, threatens some of the rarest plants and animals on our planet. It is crucial to figure out how the future living spaces for these rare species might change so we can focus our efforts on preserving specific areas. 

In this project, you can choose a rare species you're interested in and gather online data about where it currently exists. This is a great idea for a biology research project if you’re interested in the environment, ecology or rare plant and animal species, in which you can find out how to use species distribution modeling to map where it lives now and where it might thrive. 

5. Complex Relationships in Coral Reefs

Coral reefs worldwide are struggling, and one big reason is "coral bleaching," making the reefs look white, as you might have seen in the news. Coral bleaching happens when the teamwork between the coral animals and the tiny, helpful algae inside them breaks down. These coral and algae buddies can handle different temperatures, but we don't really know why. 

This biological project can be about reading what scientists have researched about this teamwork and determining what factors can tell us when corals might turn white and how well they can handle temperature changes.

Genetic Project Ideas

If you want to base your project on genetics, we have a few ideas you can look at. 

1. Understanding the Relationship between Genetics and Height 

Epigenetics studies how heritable cellular phenotype or gene expression changes occur without altering the DNA sequence. Such changes are affected by lifestyle and diet. In these biochemical projects, you can analyze the open dataset on identical (or monozygotic) twins to find what biological features are shared between monozygotic twins and which are not. The latter might be affected by non-genetic factors that control these features

You will learn how to use the R tool to look at and analyze data, and use statistical tools to identify significant differences between groups, and, in the end, showcase your research with graphics to communicate it effectively to the audience. 

2. Exploring personalized medication

Just like fingerprints, each of us has a unique genetic code that determines things in our body, like our hair color, height, and eye color. Even diseases like cancer have their own unique codes inside the malignant cells that define important features of the  a tumor. 

For decades, everyone with a specific cancer has been treated the same way with surgery, chemo- or radiotherapy, even if their malignant cells are different. That's where one of the most interesting biology topics for research, personalized medication, comes in. 

It's a new and exciting way to treat diseases. Personalized medicine aims to use the disease's genetic code to customize the treatment to that particular individual. This domain of biology has a lot of published research and a lot of room for new research as well. 

One thing you can do for your biology project subject is to pick one disease whose treatment can really benefit from personalized medication and write a research paper on it based on the work of reputable researchers. 

3. The genetics of neurodevelopmental disorders

Many neurodevelopmental or psychiatric disorders like autism spectrum disorder or schizophrenia have a strong genetic basis. What genes are involved? What proteins do they produce and what are their functions? How do these genetic changes affect brain development and function? Can this knowledge help scientists develop new drugs to treat conditions like schizophrenia that is still being treated with the same drugs as 50 years ago?

This project will allow you to read exciting research that has been published over the last few years, and learn about genetics and neuroscience, two of the most exciting areas of biology and medicine. You will develop skills in scientific research and ways to present complex ideas to an audience. 

Projects based on exciting biological topics allow students to explore the science of living things and get hands-on experience with everything they learned in high school. From investigating altitude's impact on cognition in human beings to exploring genetically engineered mosquitoes, these projects help in understanding biology. 

Students develop critical thinking and research skills in each biology project, apply classroom knowledge, and communicate findings effectively. These projects provide students the freedom to explore individual interests and pave the way for future scientific endeavors. 

If you're interested in conducting biology research, consider finding a mentor who can guide you through your innovative biology project ideas. At Indigo Research, you can start your research at any time of the year, building on the knowledge and skills you've acquired from your internships or academic coursework.

List of biology project topics for class 11, vermicomposting, blood groups, sample biology project class 11.

Here are the two types of Biology Projects for students:

Source based Project: In this type of biology project, students can choose a topic and collect the information through different sources such as books, websites, and journals.

Research Project: In this type of biology project, students are required to perform the scientific experiment in school laboratories. Students must follow proper procedures and obtain the results on their own research. The results obtained through the experiments must be included in the conclusion of the project.

Biology Project Ideas for Class 11 Students

Here are a few biology class 11 projects explained in detail:

Aim: This project is about the various components of Food. Food is a nutritional material taken for growth work, restoration and preservation of life cycles by an organism. For living creatures, food is a kind of power. We have to feed to provide us with energy known as staple foods. Nutrition is the analysis of food material compositions and the amounts of food materials needed by our body for growth, maintenance and survival.

Theory: Some diets have more sugars, and others may have more fat. Many foods contain all the main nutrients but in different proportions, such as sugars, fats, proteins. So we will ensure that our body receives all the necessary nutrients in sufficient amounts by consuming a range of various foods.

• Carbohydrates
• Dietary Fiber

Requirements: The above requirements are needed in edible forms to classify the components of food.

Aim: The aim of this project is about Pollution, of different forms, which has a major impact on the environment and culture. About 4.2 million deaths per year are a product of external air pollution, according to the Health Organization. In countries where air quality crosses WHO guideline thresholds, ninety-one percent of the world ’s population now lives.

Theory: Pollution need not necessarily be caused by organic compounds such as particulates (like smoke and dust) (like smoke and dust). Forms of energy such as vibration, heat or light may also cause emissions. These pollution-causing compounds are considered contaminants. Pollution affects the ecosystem equilibrium, even in minuscule numbers. Pollutants will work their way up the food chain to find their way into the human body finally. To discover the forms of emissions and their effects, read on.

Aim: This project is about the Non-Conventional Sources of Energy. Energy is one of the main parts of the economic infrastructure, being the fundamental input required to support economic development. A close association exists between economic growth and the use of oil. Renewable electricity sources are also considered non-conventional energy sources. 

Renewable supplies that are refilled continually by natural cycles. Examples of alternative energy sources include for example, solar energy, wind energy, bio-energy-biofuels generated sustainably), hydroelectric generators, etc. A method of renewable energy transforms power from sunshine, wind, tidal currents, sea waves, convective energy, or biomass into a form that can be used, such as heat and electricity.

Theory: The more industrialized a nation is the larger the per capita intake of electricity, and conversely. Human culture depends on numerous energy sources. It is possible to categories the two main energy sources under: 

• Conventional Sources
• Non-Conventional Sources

Aim:  The Human Genome Project was a government financed 13-year initiative begun in 1990 with the goal of identifying within fifteen years the DNA sequence of the whole heterochromatic genetic code. The Human Genome Project was treated with skepticism by many individuals in its initial periods, particularly researchers and theistic evolutionists alike.

Theory: The Human Genome Project is divided into two to discuss the universal genome sequence on the basis of the information obtained from yeast and worm studies (IHGSC, 2001). The first step, called the shotgun process, differentiated human chromosomes into sufficiently sized DNA segments, which were then subsequently subdivided into compiled smaller, alternating DNA fragments.

Aim: This project is about Malnutrition. Every living organism needs food for its sustenance on earth, which is very important for carrying out its mentally and physically related activities, development and growth. Man needs such nutritional requirements such as sugars, proteins, carbohydrates, vitamins, nutrients, starch, and water in the proper proportion and adequate quantity for natural progress and expansion that he gets from the food he consumes. A healthy diet is considered a meal that contains all these important nutrients in the right proportions.

Theory: The loss or even imbalance of any of these in the diet of individual results in eating disorders, which can be collectively considered malnutritional disorders. Malnutrition is the disease in which persons become poor and ill due to inadequate and unbalanced nutrition. Due to hunger, lack of schooling, misinformation and regular pregnancies, a substantial number of individuals in our nation and other developing nations suffer from malnutrition.

Aim: This project is regarding Sickle Cell Anemia and its Prevention. The most frequent cause of sickle cell disease is sickle cell anaemia (SCD). SCD is a severe condition in which the body creates red blood cells that are sickle-shaped. “Sickle-shaped” means that like a crescent, the red blood cells are shaped.

Theory: There are disc-shaped regular red blood cells and they look like doughnuts without holes in the middle. They pass through the blood vessels with ease. An iron-rich protein called haemoglobin is present in red blood cells. There are stiff and sticky sickle cells. The blood vessels in the brain and other organs appear to block blood flow. Pressure and organ injury can be caused by the blocked blood supply. It may also increase the risk of infection as well.

Aim: This is the Monsoon of India Project Study – Our nation is a land of great weather diversity. Seasonal fluctuations as well as variations in both day and night are broad. In weather, these changes are found. A word derived from the Arabic word ‘mousam,’ which implies season, for monsoon use.

Theory: The four months of June, July, August, and September are at the centre of the rainy season in almost all of India. This is the wet season. But it continues to decline from south to north and from east to west. It is hardly two months in the remote northwest. During his time, between three-fourths and nine-tenths of the total rainfall is concentrated.

This may give one an understanding of how it is spread unevenly over the year. By early June they are high enough to draw the trade winds of the southern Hemisphere, the low pressure levels over the north – western plains are further exacerbated. They cross the arctic circle from the Indian Ocean and reach the Bay of Bengal and the Arabian Sea, only to be caught up in the air circulation over India. These south-east trade winds are of oceanic origin.

Aim: By applying manures and fertilisers to the soil of crop fields, the lack of plant nutrients and organic matter in the soil is compensated for. The primary sources of plant nutrients are both manure and fertiliser, so they are used in crop growing.

Theory: In addition to water CO2 and sunlight plants, no elements were required for their growth. These are classified as nutrient elements. From the salt of these elements found in the soil, plants receive their elements. But soil in these elements becomes low after prolonged cultivation of plants. The material applied to the soil to cover up the shortage of the vital components was called fertilisers by increasing soil fertility.

Manures are fertilisers that are natural. They are bulky sources of organic matter that provide small amounts of nutrients but huge amounts of organic matter. Manures include farmhouse compost (FYM), manure, biofertilizers, agricultural residues, etc.

Aim: Trees are an integral part of the Earth’s biosphere. In the life of man, they play an important role. Children play under them and in their cool shade, weary travellers refresh themselves. They’re bringing us fruit to eat and burning firewood. In order to build houses and furniture, we need trees.

It was a tree in a woodland on the slope of a hill. Perhaps the furniture in your classroom is made from trees that once flourished in the Assam or Kerala forests. Trees thus supply us with all of life’s conveniences.

Theory: Trees do a lot more than offer us the conveniences that we have described. They continue to sustain the survival of man by providing the world with oxygen that is important to live. When animals breathe and objects combust, carbon dioxide is the fuel the plants consume. The oxygen in the air is continually taken up and converted into carbon dioxide. 

The leaves of plants (in fact, of all green plants) absorb this carbon dioxide and decompose into carbon and oxygen with the aid of sunlight. The carbon is used to make starch 70, and the oxygen is released into the air, eliminating the animals with the chemicals used. But this would soon mean the animals would die for lack of oxygen.

Aim: The atmosphere on Earth has changed several times in the past. From the south, tropical forests have expanded into more temperate regions (or milder, colder climates). Millions of years later, polar caps extended from the north, surrounding great glaciers in most of the northern United States, Europe and Asia. Almost all scientists today consider that human activities are altering the world.

Theory: The air inside of a greenhouse remains warm under bright sunlight. The greenhouse glass makes light energy and some of its heat energy into the sun. Within the greenhouse, this heat builds up. You were only showing a slight greenhouse effect. What will occur if the Earth’s atmosphere shifted by this greenhouse effect? 

What occurs inside a car parked in the sun is another type of a greenhouse. The light and heat of the sun gets inside the vehicle and like the plastic bag surrounding the jar, is stuck inside. Within a vehicle, the temperature can reach over 120 degrees Fahrenheit (49 degrees Celsius).

Requirements: Two identical glass jars, 4 cups cold water, 10 ice cubes, One clear plastic bag and a Thermometer.

Best Biology Project for Class 11

Biology is a vast subject and has a vast range of concepts when it comes to making projects. Almost all branches of Biology are equipped with learning and experiment. Discussed below are some of the popular Biology project for class 11th with required materials.

Vermicomposting is a biological process of making use of biodegradable waste to make manure which is seen as a sustainable alternative to chemical fertilizers. The process involves earthworms and microbes that decompose plant waste into manure when conducted under the suitable environment. It can be easy and interesting Biology project for class 11th. There are two methods of vermicomposting—Bed Method and Pit Method. Bed method is more advanced and is widely used while the pit method is lesser used due to poor aeration and waterlogging. As such, there are no specific materials that you need, a large bin or a tank is required to store the waste and earthworms are to be put in. The temperature is to be maintained for which the tank can be covered with polythene or dry grass. 

Blood is connective tissue and is crucial in the transportation of oxygen to the cells. As per the ABO blood grouping system invented by Karl Landsteiner, there are four types of blood groups which include A, B, AB and O. All these blood groups are determined by their antigens and antibodies. It is important that the blood group of both the donor and receiver should match during the transfusion to avoid a life-threatening situation. The aim of the project would be to understand the basics of blood grouping system. This can be a very exciting Biology project for Class 11 as it requires a good amount of lab work and handling lab equipment.

Materials Required: Toothpicks; Blood Lancet; Alcohol Swabs; Biohazard Disposal Container; Blood Sample; Clean Glass Slide; Sterile Cotton Balls.

Types of Projects

Projects can be classified into two types:

1. Linear Projects

Linear projects are those projects in which the sequence of tasks is fixed and the tasks can be completed in a specific order. In a linear project, a task can be started only after the previous task is completed.

2. Non-linear Projects

Non-linear projects are those projects in which the sequence of tasks is not fixed and the tasks can be completed in any order. In a non-linear project, a task can be started before the previous task is completed.

Food and its Components

Food is any substance that is eaten to provide nutritional support for the body. The body obtains its energy and nutrients from food. The main components of food are carbohydrates, proteins, and lipids.

Pollution refers to the release of pollutants into the environment. These pollutants can come from a variety of sources, including factories, automobiles, and agriculture. Pollution can cause a variety of problems, including smog, acid rain, and water pollution.

Vermicomposting

is the process of using worms to compost organic matter. The worms eat the organic matter and their droppings are a rich, organic fertilizer.

The worms are used to compost organic matter. They eat the organic matter and their droppings are a rich, organic fertilizer. The worms eat the organic matter and their droppings are a rich, organic fertilizer.

Blood Groups

There are four blood groups: A, B, AB, and O.

Your blood group is determined by the proteins found on the surface of your red blood cells. These proteins are called antigens.

There are two main antigens: A and B.

If you have the antigen A, you are group A.

If you have the antigen B, you are group B.

If you have both antigens (A and B), you are group AB.

If you don’t have either antigen (A or B), you are group O.

Your blood group is also determined by the antibody in your blood.

If you have the antibody A, you are group A.

If you have the antibody B, you are group B.

If you have both antibodies (A and B), you are group AB.

If you don’t have either antibody (A or B), you are group O.

Blood Pressure

Blood pressure is the pressure exerted by circulating blood on the walls of blood vessels. The pressure is determined by the force and volume of the blood. When the heart contracts, it pumps blood into the aorta and other large arteries. These vessels have muscular walls that can contract and expand to accommodate the flow of blood. The pressure of the blood in these vessels can be measured with a sphygmomanometer. The pressure is expressed in millimeters of mercury (mm Hg).

Mitosis in the Onion Root Tip Cells

The mitotic process in onion root tip cells is similar to the process in other types of cells. The cells undergo interphase, during which the DNA is replicated. The cells then enter mitosis, during which the chromosomes are divided equally between the two daughter cells. The cells then undergo cytokinesis, during which the cytoplasm is divided equally between the two daughter cells.

Vitamins or Sources of Vitamins

A vitamin is an organic compound and a vital nutrient that an organism requires in limited amounts. An organism cannot make vitamins on its own, so they must be obtained from food.

There are 13 essential vitamins: vitamin A, vitamin B1 (thiamine), vitamin B2 (riboflavin), vitamin B3 (niacin), vitamin B6 (pyridoxine), vitamin B7 (biotin), vitamin B9 (folic acid), vitamin B12 (cobalamin), vitamin C, vitamin D, vitamin E, and vitamin K.

The best sources of vitamins vary depending on the vitamin. For example, vitamin A is found in liver, fish oils, and eggs, while vitamin C is found in citrus fruits and berries.

Transpiration of Plants

Water is transpired from the leaves of plants. The water is drawn up from the roots by the plant’s vascular system. The water is then carried to the leaves and released into the atmosphere.
