Conduct Galileo's Famous Falling Objects Experiment

Science Fair Project Idea

Scientific Method

Standing on a balcony near the top of the Tower of Pisa in Italy, a young scientist dropped two balls into the crowd below. The scientist, young Galileo, was not trying to knock his fellow professors on the head, but was trying to prove his theory that all objects fall to earth at the same rate, regardless of their mass. Was Galileo's theory correct? In this science project, you will get to test it out for yourself! Look out below! Read more

Tricks for Treats: How Long Does It Take to Train Your Pet?

Science Fair Project Idea

Scientific Method

Have you ever been to an animal show and seen a sea lion balance a ball on his nose, or a tiger jump through a hoop? Or maybe you've met dogs who can sit, fetch, shake, or beg on command. The range of tricks that you can teach animals is amazing, but how does animal training work, and how long does it take? Find out in this trick-and-treat filled science fair project! Read more

A Magnetic Primer Designer

Science Fair Project Idea

Scientific Method

How do scientists "copy" DNA? They use a process called the Polymerase Chain Reaction, or PCR. The key to making this process work is having a short piece of DNA, called a primer, that will stick to the larger piece of DNA you want to copy, called a template. In this science project, you will test how the number of matches and mismatches in a primer will affect its ability to stick, or anneal, to the DNA template during PCR. Read more

Can the Color of Your House Reduce Your Energy Footprint?

Science Fair Project Idea

Scientific Method

Did you know that the color of your house could save money? Do this experiment to see which colors regulate temperature best in different environments. Then convince your parents to paint the house and save some money on their energy bill. Maybe they will be so happy they will also increase your allowance! Read more

A Puzzling Parallax

Science Fair Project Idea

Scientific Method

Do you enjoy going stargazing? In a good location on a clear night, you can see a huge number of stars twinkling in the night's sky. Have you ever wondered how far those stars are from us? Ancient astronomers actually discovered a way figure this out, measuring the distance from Earth to faraway stars. How did they do it without modern technologies? In this astronomy science project you will find out by exploring the link between the distance of an object and perspective (also known as… Read more

A Solar-Powered Robot Bug

Science Fair Project Idea

Scientific Method

"How do you frighten a grasshopper? And what does that have to do with light?" These are a couple of questions you're probably asking yourself after reading the title. Well, The Frightened Grasshopper Solar-Powered Bug is actually a toy grasshopper that vibrates when it is placed in sunlight or near a lightbulb. It stores up the energy from light, and converts it into motion. You will use this fun toy to explore how the brightness of the light affects the motion of the solar-powered insect. 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

Building Beaches

Science Fair Project Idea

Scientific Method

A day at the beach is a wonderful way to spend time with your family and friends. You can swim, play games, and build sand castles. But have you ever thought about how all of that sand got there and wondered why the shoreline weaves in and out of the ocean? In this science project, you will investigate how ocean waves build beaches by making a model of the beach and shoreline. All you need is a tiny surfer and a beach volleyball court for your model, and you can imagine that you are in… Read more

Are There Bugs Under Your Feet?

Science Fair Project Idea

Scientific Method

Look out! When you walk on the grass, you are squishing millions of micro-invertebrates! Just kidding, these animals are too small to squish. Learn how to catch them by making a Berlese funnel in this fun project that will teach you about soil. Read more

Centripetal Force

Science Fair Project Idea

Scientific Method

What keeps you in your seat of a giant loop-de-loop roller coaster? Surprisingly, it is not the seatbelt but the seat! It works because of something called centripetal force and it does much more than make a great roller coaster. It keeps a satellite in orbit and you in your bicycle seat during a turn. How does it work? Read more
