thumbnail Do ants sometimes ruin your picnic? There are some chemical ant repellents you can spray to keep them away, but who wants to spray poison all over their food? In this science project you can investigate some less toxic solutions that may be around your home so that your next picnic will not become an ant buffet! Read more

thumbnail Have you ever dyed eggs? Turning eggshells from white into different, dazzling colors can be a lot of fun! To do this, most people buy dye tablets to make different colors in a liquid bath. They then dip the egg into the liquid and wait till it turns the desired color. You can dye eggs in many other ways, and one neat method uses silk ties. Sounds strange to use clothing to dye eggs, right? But it actually works really well! In this science project, you will dye eggs with old or used… Read more

Safety Adult supervision is recommended when using scissors and required for using the stove. A well-ventilated stove area, or dust masks, are needed to avoid breathing in vinegar and dye fumes. Do not eat the eggs after dyeing them.
Science Fair Project Idea
thumbnail Do you like making things with play dough or modeling clay? Wouldn't it be cool if you could add a bunch of lights to your creations? In this science project, you will make play dough that conducts electricity, and we will introduce you to some new types of circuits so you can add more lights to your artistic creations. This science project is the second in a three-part series on "squishy circuits," which can all be done with the same materials. We recommend doing the science projects in order. Read more

- Less Details
Time Required Average (6-10 days)
Prerequisites You should understand the Introduction material in Make Your Play Dough Light Up, Buzz, & Move!—the first science project in the "Electric Play Dough" series—before doing this science project.
Material Availability This science project requires a Squishy Circuits Kit and ingredients to make conductive and insulating play dough. See the Materials and Equipment list for details.
Cost Low ($20 - $50)
Safety Ask for an adult's help when using the stove to make the conductive play dough. Never connect the battery pack's terminals directly to each other; this is called a short circuit and can make the batteries and wires get very hot. Do not connect the LEDs directly to the battery pack without using play dough; this will burn out the LEDs.

Have you ever wanted to take a short cut? How about when doing your math homework? In this experiment you can learn how estimation can save you time doing math calculations. But beware, some estimations are better than others! Can you match this sample size with the best population? How accurate are your estimation skills? Read more

Science Fair Project Idea
Everybody's favorite card in UNO® is the wildcard—why? Because it can stand for any card you want! Your computer uses the same idea. A wildcard on your computer can stand for anything you want when you search. Do this science project to find out if using wildcards to conduct a search can help you find more of what you're looking for. Read more

Science Fair Project Idea
thumbnail Just one sheet of paper can lead to a whole lot of fun. How? Paper planes! All you have to know is how to fold and you can have a simple plane in a matter of minutes! But what design should you use to build the best plane? In this aerodynamics science project, you will change the basic design of a paper plane and see how this affects its flight. Specifically, you will increase how much drag the plane experiences and see if this changes how far the paper plane flies. There is a lot of cool… Read more

thumbnail Did you know that your body has a built-in cooler? And it might not be what you think! Sweat is produced when you are hot, but its purpose is actually to cool your body as the water in it evaporates from your skin. In this science fair project, you'll use the energy produced when water evaporates to cool down chocolate-covered candy so it doesn't melt. Read more
