• B.A., Physics and Mathematics, Hastings College

Great 4th-grade science fair projects involve answering a question, solving a problem, or testing a hypothesis. Usually, a teacher or parent helps work out the hypothesis and design the project. Fourth graders have a good understanding of scientific concepts, but they may need help with the scientific method and organizing a poster or presentation. The key to developing a successful project is finding an idea that is interesting to a 4th grader.

Experiment Ideas

The best experiments usually begin with a question to which you don't know the answer. Once you've formulated a question, you can design a simple experiment to help figure out the answer:

• Do cockroaches have a preference for direction? Catch and release cockroaches. Which way do they go? Is there a common trend or not? You can try this project with ants or other crawling insects as well.
• Do colored ice cubes melt at the same rate as clear ice cubes? Add food coloring to an ice cube tray and compare how long the colored cubes take to melt compared to the regular ones.
• Does magnetism travel through all materials? Put different materials between a magnet and metal. Do they affect how strongly the magnet is attracted to the metal? If so, do they all affect the magnetic field to the same degree?
• Do all crayon colors last the same? Draw a really long line with one color, then draw the same length of line with another color. Are both crayons the same length?
• What is the effect of microwaving seeds on their germination rate? Test seeds that sprout quickly, like radish seeds, and different microwave times, such as 5 seconds, 10 seconds, 30 seconds, one minute. Use a control (no microwave) treatment for comparison.
• Will seeds germinate if you soak them in a liquid other than water? You can try milk, juice, vinegar, and other common household liquids. Alternatively, you could see if plants will grow if they are "watered" with liquids other than water.
• Make a simple homemade windmill. What is the best number of blades for the windmill?
• How much salt (or sugar) can a plant tolerate? Water plants with a different solution of salt or sugar. How high of a concentration can the plant tolerate? A related question would be to see if plants can survive if they are watered with soapy water such as leftover dishwater.
• Do birds have a preference for birdhouse material? In other words, do they seem to care if the birdhouse is made of wood or plastic or metal?
• Do worms react when they are exposed to light? Do they react differently when they are exposed to different colors of light?
• Do ants prefer different types of sugar? Test using table sugar, honey, maple syrup , and molasses.
• Can you taste the difference between foods that contain fat and fat-free versions of the same product?
• Compare the water filtration rate of different brands of coffee filters. Take one cup of liquid and time how long it takes to pass through the filter. Do the different filters affect the flavor of the coffee?
• Do white candles and colored candles burn at the same rate?
• Write messages using different types of invisible ink . Which was the most invisible? Which method produced a message that was easy to read after it was revealed?

• Conclusion report
• Visual presentation

If your science fair project includes all of these elements, you are well on your way toward a winning science fair project idea!

What Do Kids Learn Doing Science Fairs?

Kids who do science projects report greater confidence and understanding of all scientific concepts, both in what they explored and the scientific process in general.

Learning to analyze and explore data helps children approach other tasks in a logical, straightforward process which helps improve study skills and communication skills.

One of the greatest values that science fair projects bring is the ability to identify problems and work toward a solution. That is an invaluable skill that kids can use throughout life.

Of course, kids learn the basics of whatever scientific concept they are learning, plus the scientific method, which involved:

• Analyzing and Recording Data

But more than that, kids also learn other valuable skills like:

• Presenting an idea
• Creating a presentation
• Organizing data
• Analyzing data
• Patience and orderliness
• Working with others
• Precision and care
• Adapting to changes
• Communication skills

These skills are important far beyond the classroom!

Growing bacteria for science fairs.

All good science experiments start with a question – this is what you want to find out by experimenting. Here are a few example questions to get you started using the scientific method for growing bacteria:

• Is a dogs mouth cleaner than a humans mouth?
• Who has the cleanest mouth in the class?
• Do antibacterial soaps really kill bacteria?
• Which door handle in the school has the most bacteria?
• Does toothpaste kill bacteria in your mouth?
• Do dark socks create more bacteria in a shoe than white socks.
• Do hand sanitizers work to kill bacteria?
• What location in the school contains the most bacteria?
• Is there more bacteria in tap water, bottled spring water, rain water, or pond water?

Step 1 – Ask A Question: Let’s imaging that you want to answer the question, “Which door handle in the school has the most germs?”

Step 2 – Research: You can’t just jump in and start experimenting. It’s important to do a little research. Ask the school nurse which door handle he or she thinks the most germs (bacteria) are. Observe and chart which door handles get the most use, survey friends and family to get opinions and write down the results. All this information will help you narrow down which door handles are the most likely to contain germs – and which ones you should choose to use in your experiment.

Step 3 – Make a Hypothesis : This is when you make a prediction based on your research. This is not an “I think…” prediction, it is a statement that will either be proven true or false based on experimenting. An example would be, “The handle to the nurse’s room contains the most bacteria.”

Step 4 – Experiment: This particular science experiment requires a simple bacteria testing kit. You would choose several door handles that you think might contain the most bacteria. These door handles are considered the Independent Variable in your experiment because each handle is independent and you control which ones are chosen. In a typical kit you would touch a separate cotton swab to each door handle, and then touch it to the bacteria growing Petri dish so that you would have one dish for each handle. Take good notes that would include when you collected each sample and where you collected the sample, and be sure to label everything well in any experiment.

Step 5- Collect Data: In this experiment, bacteria will start to grow in the Petri dish over the next few days, and you may be surprised by just how much gross bacteria is lurking in your school. Take good notes each day and determine which dish has the most bacteria growing in it.

Step 6 – Make Your Conclusion: This is when you decide if your hypothesis is correct. If your hypothesis was, “The handle to the nurse’s room contains the most bacteria,” your experiment will show if your hypothesis was right. It is not bad at all if your hypothesis is incorrect, what is important is that you answered your question from step 1. Now pat yourself on the back for your fine scientific discovery using the Scientific Method.

Hypothesis Examples

A hypothesis is a prediction of the outcome of a test. It forms the basis for designing an experiment in the scientific method . A good hypothesis is testable, meaning it makes a prediction you can check with observation or experimentation. Here are different hypothesis examples.

Null Hypothesis Examples

The null hypothesis (H 0 ) is also known as the zero-difference or no-difference hypothesis. It predicts that changing one variable ( independent variable ) will have no effect on the variable being measured ( dependent variable ). Here are null hypothesis examples:

• Plant growth is unaffected by temperature.
• If you increase temperature, then solubility of salt will increase.
• Incidence of skin cancer is unrelated to ultraviolet light exposure.
• All brands of light bulb last equally long.
• Cats have no preference for the color of cat food.
• All daisies have the same number of petals.

Sometimes the null hypothesis shows there is a suspected correlation between two variables. For example, if you think plant growth is affected by temperature, you state the null hypothesis: “Plant growth is not affected by temperature.” Why do you do this, rather than say “If you change temperature, plant growth will be affected”? The answer is because it’s easier applying a statistical test that shows, with a high level of confidence, a null hypothesis is correct or incorrect.

Research Hypothesis Examples

A research hypothesis (H 1 ) is a type of hypothesis used to design an experiment. This type of hypothesis is often written as an if-then statement because it’s easy identifying the independent and dependent variables and seeing how one affects the other. If-then statements explore cause and effect. In other cases, the hypothesis shows a correlation between two variables. Here are some research hypothesis examples:

• If you leave the lights on, then it takes longer for people to fall asleep.
• If you refrigerate apples, they last longer before going bad.
• If you keep the curtains closed, then you need less electricity to heat or cool the house (the electric bill is lower).
• If you leave a bucket of water uncovered, then it evaporates more quickly.
• Goldfish lose their color if they are not exposed to light.
• Workers who take vacations are more productive than those who never take time off.

Is It Okay to Disprove a Hypothesis?

Yes! You may even choose to write your hypothesis in such a way that it can be disproved because it’s easier to prove a statement is wrong than to prove it is right. In other cases, if your prediction is incorrect, that doesn’t mean the science is bad. Revising a hypothesis is common. It demonstrates you learned something you did not know before you conducted the experiment.
