Has your stomach ever ached so bad you felt as if it was blown up like a balloon—maybe after the big Thanksgiving meal? You may have had a large amount of gas trapped in your stomach and intestines. But where does the gas come from that makes you feel so uncomfortable, and how does it disappear again? In this activity, you will blow some bubbles to investigate how a specific medicine can help you feel better, so next time your tummy hurts because you are bloated, you will know how to cure… Read more

How Tweet It Is: Bird Songs in Classical Music

Science Fair Project Idea

Scientific Method

Do you enjoy singing contests like American Idol? Well, male songbirds have their own version of a singing competition that has been going on for thousands of years, and classical musical composers have been taking notes! In this music science fair project, you'll investigate the different instruments composers have used to imitate or create impressions of bird songs and bird calls. Read more

Can you recall how a piece of warm apple pie or a cup of hot chocolate milk tastes when you let it cool? Maybe you even prefer to have these treats at room temperature. Why is this? Can flavor change even when you are not adding ingredients, cook or bake it? Try this activity and discover how temperature influences flavor! Read more

Human-Robot Interaction: Do Looks Matter?

Science Fair Project Idea

Scientific Method

Do you think robots are cute? Funny? Scary? How do robots make you feel? What words would you choose to describe a robot? Find out how people react to robots by building and decorating your own robot in this science project. Read more

Image Compression

Science Fair Project Idea

Scientific Method

Compare the strengths and weaknesses of different digital image formats. How does the amount of compression affect a JPEG image? What happens when you save a JPEG image multiple times? Read more

Interpreting Area Data from Maps vs. Graphs: An Experiment in Visual Perception

Science Fair Project Idea

Scientific Method

Graphical methods of data presentation are a key feature of scientific communication. This project asks the question, "What's the best way to compare the land area of states: a map or a bar graph?" You'll be measuring performance on two different visual discrimination tasks: comparison of areas vs. comparison of position on a common scale. Which method is more accurate? Which method is faster? This project will get you thinking about how to find the best way to communicate scientific… Read more

"Grasshopper" by Ryan Wood There are thousands of species of insects in our world, and each are adapted to survive in their habitat. In this activity, students will learn what an insect is and what some of their adaptations are. Then they will put their knowledge into play by "creating" an insect that is adapted to live in their assigned environment. Read more

Investigate Native Plant Evolution with Chloroplast Sequencing

Science Fair Project Idea

Scientific Method

Native plants are important for both ecological and medicinal reasons. However, most native plants are not very well studied. One way to know more about these plants is to understand which other species of plants they are most closely related to. In this science project you will sequence part of the chloroplast genome from a native plant and use this information to determine its evolutionary relationship to other species of plants. If the plant you chose has not been sequenced before, you can… Read more

Investigating Fluid Viscosity

Science Fair Project Idea

Scientific Method

You can measure the viscosity of a fluid using a glass tube and a marble with slightly smaller diameter than the tube. Seal one end of the tube. Fill the tube with the fluid to be tested. Drop the marble into to the tube and measure the time it takes to fall a fixed distance. Repeat the measurement several times, and use the average value. How does viscosity change with the amount of sugar dissolved in water? How does viscosity change with temperature? Read more
