Science Fair Project Idea

Scientific Method

Does your hair go crazy when the weather turns damp? Did you know that strands of hair can relax and lengthen when the humidity increases and then contract again when the humidity decreases? In fact, hair strands can be used as the basis for a hygrometer, a device which measures the humidity level in the air. Will a hygrometer help you to predict bad hair days(!) or can you use it to help predict the weather? Read more

Which Wheat Flour Has the Most Gluten?

Science Fair Project Idea

Scientific Method

Close your eyes for a moment and think about your favorite cake, pasta, and crusty bread. OK, you can open your eyes now, and please do not drool on your computer! What was the cake you pictured like? Was it light and fluffy? Did you imagine pasta with a silky, smooth texture? Was the bread you pictured wonderfully chewy? Did it give your jaws a workout? In this science fair project, you will explore an amazing substance in these foods, called gluten, and discover why these foods, all made from… Read more

Soil Color and Moisture

Science Fair Project Idea

Scientific Method

Have you ever taken a step onto what appeared to be dry ground, only to find yourself ankle-deep in mud? Yuck! When you walk through damp soil, it can be a very messy experience. How can you tell if soil is wet or dry before you step on it? In this science project, you will investigate whether the color of the soil can help you determine how dry or wet it is. Read more

Simulate Microchip Clean Room Contamination with Crayon Leaf Rubbings

Science Fair Project Idea

Scientific Method

Have you ever made a leaf rubbing or imprint using paper and crayons? What do you think would happen if you got dirt or sand on the leaf? Would it mess up the result? In this project you will find out and learn about how this is related to the process of making the microchips that run our phones, computers, and other electronic devices. Check out this page for more science projects related to this process. Read more

Mixing Mystery: Why Does Tumbling Sometimes Separate Mixtures?

Science Fair Project Idea

Scientific Method

What do sand and cereal have in common? They are both granular materials, which means they are made up of solid particles, but they can actually flow like liquid. When two granular materials with very different-sized particles are mixed, you can actually separate each type by putting them in a rotating device called a tumbler. In this science project, you will examine how common household granular materials behave when mixed together in a moving container Read more

A Soluble Separation Solution

Science Fair Project Idea

Scientific Method

Have you ever mixed together salt and sand? It is fun to see how all of those tiny grains of salt and sand mix together! But what if you had to separate them out again? Do you have nightmares of tiny tweezers, a magnifying glass, and hours spent picking grains of salt and sand apart? Do not be afraid, there is another way! In this chemistry science project you will use the differences in solubility between salt and sand to find out the simple "solution" to this problem. Read more

Do Migratory Birds Like It Hot?

Science Fair Project Idea

Scientific Method

Why do birds migrate? Do all birds have the same reasons for migrating? Where do they go when they migrate? These are questions scientists have asked for centuries. The more species for which they gather data, the more specific the answers become. In this science project, you will choose a species to investigate, then access and evaluate real data collected by scientists to start answering those questions yourself! Read more

Memory Mnemonics

Science Fair Project Idea

Scientific Method

Have you ever had to remember a long list of planets or the state capitals? These kinds of lists are full of interesting facts, but they can be hard to remember, especially for tests. What could you do to remember the list better? In this human behavior science fair project, you will learn about a memory technique called mnemonics (pronounced nuh-MAH-nicks) and investigate whether using mnemonics can help you and your friends remember lists of words. Read more

How Long Does Trash Last?

Science Fair Project Idea

Scientific Method

Even though many cities have recycling programs, a lot of trash still ends up in the dump. Find out which materials will break down and which materials won't. Will the results of this experiment change which products you often buy? Read more

Veggie Snap! Modifying Bending Stresses in a Flexible Rod

Science Fair Project Idea

Scientific Method

Have you ever broken a fishing rod? Or seen a treetop bend over and touch the ground (or even snap off) during an ice storm? These are examples of the effect of bending stresses on flexible rods. There are scientists who actually study this phenomenon and discover ways to prevent breakage, which leads to stronger fishing rods, building materials, car parts, and more. In this science project, you'll explore the bending stresses in flexible rods by testing asparagus stalks. Read more
