Art Bot: Build a Wobbly Robot That Creates Art

Science Fair Project Idea

Scientific Method

Do you like drawing or painting? What if you could build a robot that creates its own art? In this project, you will create your own Art Bot, a robot with markers for "legs" that wobbles across a piece of paper, creating drawings as it moves. You can then customize your robot to change how it draws. This is a beginner-level project with no robotics experience necessary, so if you want to try building your own robot, this is a great place to start! Read more

The Bouba-Kiki Effect

Science Fair Project Idea

Scientific Method

Have you ever wondered if some shapes have certain "sounds" to people, even if they have different native languages? For example, does everyone match certain physical characteristics, like sharpness or roundness, with certain sounds? Are there certain human sounds with meanings that can cross the language barrier? In this science project you will investigate this by testing the Bouba-Kiki Effect—will it turn out that abstract visual properties can be linked to sound? Read more

Bubble-ology

Science Fair Project Idea

Scientific Method

Making your own bubble solution is fun, but sometimes the bubbles don't seem to work as well as the solutions you buy in the store. In this experiment you can test if adding corn syrup or glycerin to your bubble solution will make it just as good as the stuff you can buy. This experiment will have you blowing bubbles! Read more

Yeasty Beasties

Science Fair Project Idea

Scientific Method

While looking at a package of dry yeast it is hard to believe that the package has organisms in it that are alive. But add the right ingredients and presto, the mixture becomes a bubbly, oozing, mess of life! What are the right ingredients? What does that yeast need to become active? Do this science project and figure it out for yourself! Read more

Cabbage Chemistry

Science Fair Project Idea

Scientific Method

This experiment is for all the kids out there who love boiled cabbage! You say you do not like cabbage? Well maybe you will like this amazing color-changing liquid you can make with cabbage. Which solutions around your house can make the cabbage juice change color? Find out while you learn about acids and bases and how to test for them. Read more

Liver Stinks!

Science Fair Project Idea

Scientific Method

Sometimes science can be really messy or use pretty disgusting ingredients. That is what it takes to understand how the world works, even if the experiment isn't pretty. Do you like chemical reactions that stink and ooze foamy bubbles? Do you think it sounds fun to make a super gross liver smoothie? Then this is the experiment for you! Read more

Electric Play Dough Project 1: Make Your Play Dough Light Up & Buzz!

Science Fair Project Idea

Scientific Method

Do you like playing with play dough; or modeling clay? Wouldn't it be cool if you could add lights, sound, or even motion to your play dough creations? In this project, you will use play dough that conducts electricity, which will allow you to connect lights to your sculptures! This project is the first in a three-part series on play dough circuits, which can all be done with the same materials. We recommend doing the projects in order. Read more

Candy Snap

Science Fair Project Idea

Scientific Method

Have you ever broken a candy bar in half to share with someone? Some might snap in half quite cleanly, but others might be gooey and flexible. If you stick a candy bar in the freezer, will this change how the materials break? Try this sweet project to find out! Read more

Ow, My Tummy Hurts! The Biology and Chemistry of Gas Relief

Science Fair Project Idea

Scientific Method

Have you ever wondered why bubbles form when you mix soap and water? Is it possible to mix soap and water without making bubbles? Medical doctors actually study similar questions when they treat patients who have too much gas trapped in their digestive system, which can cause pain and bloating and also signal a serious medical problem. Some drugs, including one called simethicone, can help relieve extra gas in the digestive system. In this science project you will find out how simethicone… Read more
