Spread the Soap, Not the Germs

Science Fair Project Idea

Scientific Method

Do you wash your hands? You should— it's the best way to prevent the spread of germs. But germs can be tricky; they find nooks and crannies to hide in, so it takes good hand-washing technique to get rid of them. In this science project, you'll investigate which parts of the hand are the most difficult to wash germs off of. Read more

Sprouting Sweet Potatoes Slips

Science Fair Project Idea

Scientific Method

Have you ever enjoyed eating a tasty sweet potato? They can be served as yummy mashed sweet potatoes with melted butter, turned into golden-brown sweet potato fries, or prepared in many other scrumptious ways. Did you know that you can make a sweet potato grow into a sweet potato plant, and grow several sweet potatoes this way? In this science project, you will grow your own sweet potato plants and investigate what part of the sweet potatoes is needed to grow the plants. Read more

Squirmy Wormy: Which Soil Type Do Earthworms Like Best?

Science Fair Project Idea

Scientific Method

Do you think worms are gross? Or that they are only good for birds or fish to eat? Well, in this zoology science project, you will find out that this lowly animal helps to put food on your table, too, by all the hard work that it does in the dirt. In this science project, you will discover in what kind of soil it likes to do its work. It is wiggly good fun! Read more

Squirrel Obstacle Course: How Far Can Squirrels Jump?

Science Fair Project Idea

Scientific Method

This project idea is inspired by former NASA engineer Mark Rober's "Squirrel Ninja Obstacle Course". You do not need to build a full obstacle course as intricate as Mark's (although you certainly can if you want to!) to make this into a fun science project. For example, how far can squirrels jump? You could test this question by building a mobile post and placing it next to a bird feeder. The bird feeder in Figure 1 is mounted on a metal pole. The pole is protected by a squirrel baffle, a… Read more

Squishy Robot Simulator

Science Fair Project Idea

Scientific Method

What do an octopus, an elephant's trunk, and an earthworm have in common? They are all squishy, bendable and flexible because they do not have any bones inside. You might not typically think of robots as "squishy," but scientists are increasingly trying to create soft robots that look and move like animals. In this project you will use a "soft robot simulator" to design and race your own squishy robots. Can you come up with the fastest design? Read more

Static Electricity Science: Weekly Science Project Idea and Home Science Activity Spotlight

Blog Post

In this week's spotlight: an electricity project and family activity that takes the zap out of static electricity. What causes the buildup of static electricity and may cause you to get "shocked" when wearing, rubbing up against, or touching certain materials or objects? What does what the object is made of have to do with static electricity? In this project, you and your family can build a cool tool, an electroscope, to detect electric charges and test to see how different materials… Read more

Have you ever noticed that some types of clothes are more susceptible to static cling than others? For example, a wooly sweater can have a lot of static cling, but clothing made out of cotton doesn’t get static cling nearly as much. How well do other materials around the house produce static electricity? In this science activity, you’ll explore this by making a simple, homemade electroscope and testing it out. The results may shock you! Read more
