Come One, Come All! Explore the Effect of Light on the Speed of the Amazing Rotating Radiometer!

Science Fair Project Idea

Scientific Method

Radiometers are fun-to-watch novelty items, but they also have a distinguished scientific history, having been studied by James Clerk Maxwell and Albert Einstein. A radiometer has a set of four vanes (like small sails) connected to a spindle that is free to rotate. When the radiometer is placed in bright light, the vanes and spindle start to spin. It looks like a magic trick, but there is a scientific explanation for this weird behavior. In this science fair project, you will experiment with… Read more

Comparing the Sweetness of Sugar & Sugar Substitutes

Science Fair Project Idea

Scientific Method

Cake, cookies, pie, ice cream, hot chocolate, lemonade... Yum! What do all these delicious treats have in common? Sugar. In addition to providing sweetness, sugar adds bulk, flavor, and structure to foods. But is it necessary to add sugar to achieve sweetness? Can the same sweetness be achieved using sugar substitutes like artificial or natural sweeteners? In this project, you will test sugar and sugar substitutes and compare the sweetness of each in relation to sugar. In the end, your day will… Read more

Comparing Vocal Ranges: How High and Low Can Your Voice Go?

Science Fair Project Idea

Scientific Method

What is the highest note you can sing? How about the lowest? Do you think males and females can reach the same notes? How about children and adults? Find out the answers to all these questions in this "note"-worthy science fair project! Read more

Cookies: Can You Blame the Burnt Ones On the Cookie Sheet?

Science Fair Project Idea

Scientific Method

Have you ever bitten into a beautiful golden-brown cookie only to realize in dismay that the bottom is burned and black? What causes that uneven baking? Can it be prevented? You can discover the answer by conducting a science fair project to determine whether different types of cookie sheets result in noticeably different cookies. First you'll need to do some background research to figure out what kinds of baking sheets you can buy. For example, there are aluminum, steel, insulated, and… Read more

Cornbread Science: Weekly Science Project Idea and Home Science Activity Spotlight

Blog Post

In this week's spotlight: a food science project and family activity that explores the role of baking powder in baking. In this pair of projects, experiment to see the affect of baking powder on corn bread muffins for a clear visual look at what happens when you use more or less in your recipe. Does a light and airy muffin indicate one with or without baking powder? How does the density or weight of a muffin change in relation to the amount of baking powder used? What happens if you use… Read more

A hot summer day is the perfect time to go to the beach and cool down in the brisk ocean water. But it's not only the water that has a cooling effect at the beach. Have you ever noticed that there always seems to be a cool breeze blowing from the ocean to the shore? Where does the wind come from? In this activity, you will build a model of the ocean and the beach to find out—so next time you go to the beach, you will know why the sea breeze is blowing! Read more

Do you enjoy watching mysteries or crime investigation shows? Every criminal leaves behind evidence at the crime scene. The trick to catching the criminal is collecting all of the evidence and making sense of it. This is what a forensic expert does. In this bloody, Halloween-themed science activity you’ll be correlating the size of blood stains to the distance they fell, but don’t get too grossed out; you’ll be doing it with fake blood. If you like figuring out mysteries, this… Read more

CRISPR Gene Editing of Escherichia coli

Science Fair Project Idea

Scientific Method

Many scientists are currently very excited about CRISPR, as it has the potential to revolutionize gene editing. But what exactly is CRISPR and what does it do? CRISPR is a novel tool in gene editing that allows the modification of genetic DNA at specific target sites in many different organisms. Researchers have high hopes that this technology can, one day, cure genetic diseases, as mutated DNA sequences can easily be corrected. In this project, you will use CRISPR to mutate a DNA sequence… Read more

Crossed Up: Does Crossed Hand/Eye Dominance Affect Basketball Shooting Percentage?

Science Fair Project Idea

Scientific Method

Everyone's used to the idea that people are either right-handed or left-handed for particular tasks. That is, one hand is preferred (or dominant) over the other for a particular task. Did you know that people also have a dominant eye? This project is designed to look for consequences of having the dominant hand and eye on the same side of the body (uncrossed) vs. having the dominant hand and eye on opposite sides of the body (crossed).
