What's Going On Behind Those Puppy-Dog Eyes?

Science Fair Project Idea

Scientific Method

Have you ever wondered what goes on in your dog's mind? Even though humans have the benefit of language, trying to understand another person's thoughts can be hard enough sometimes. Your dog can't talk, so how can you find out what its brain is capable of? The obvious answer is to study its behavior. This project will show you some behavioral tests you can use to measure canine I.Q. Read more

Where There Is Charge, There Can Be Sparks!

Science Fair Project Idea

Scientific Method

Have you ever gotten a shock touching a doorknob after walking across a carpet? Static charge is responsible for that shock. Wouldn't it be cool to save up and store all of that charge in a homemade jar? It would almost be like storing lightning. This science project will show you how to do that. Read more

If you write with your right hand, you may also prefer to draw, throw a ball, or eat food with your right hand, but have you ever wondered if your right foot is also more dominant than your left foot? What about your right eye and ear — do you prefer to use them more than your left ones? In this activity, you will get to find out whether people have a sidedness — that is, whether they generally prefer to do activities with one side of their body — and what that might say… Read more

Asteroid Mining: Gold Rush in Space?

Science Fair Project Idea

Scientific Method

You've heard of gold mining and coal mining, but think outside the box...or the planet...what about asteroid mining? Scientists, engineers, and business people believe asteroid mining is feasible, and they are in the beginning stages of long-term plans to mine asteroids for valuable resources during space missions. You don't want to miss out on all the fun; in this science project, you will come up with your own scientific plan for an asteroid mining company. We will help get you started by… Read more

Blocking RFID Readers from Reading your ID Card

Science Fair Project Idea

Scientific Method

If you've ever watched an adult pay for something by simply touching their credit card to a machine at a store, or you've done the same with a bus pass, you've seen an RFID tag in action. An RFID (Radio-Frequency IDentification) tag allows a card to be read by a computer from a short distance away. This is very convenient, but it also allows criminals to steal information about you. For instance, on the subway or the bus, someone standing next to you can use an RFID reader to access the data on… Read more

If you have ever tried to make bubbles using plain water, you may have seen that it does not work. This is because the surface tension of water is too high. When detergent is added to water, it lowers the surface tension so that bubbles can form. Other things can be added to this mixture, such as corn syrup or glycerin, to make a solution that is even better for creating bubbles. In this science activity, you will find out which solution creates the best bubbles! Read more

Build a Solar-Powered Bristlebot

Science Fair Project Idea

Scientific Method

You have probably heard about using renewable energy sources like wind and solar power to provide electricity to homes and buildings, as well as hybrid or fully electric cars that use less (or zero) gasoline. But what about solar-powered robots? As robots become more common, it is increasingly important to use "green" energy sources to power them. In this project, you will build and test a popular robot called a bristlebot — a tiny robot made using toothbrushes—that can operate on… Read more

Can Biodegradable Materials Replace Plastic as Protective Food Packaging?

Science Fair Project Idea

Scientific Method

Many foods, such as fresh fruits, vegetables, or eggs, are packaged in plastic to protect them from damage during handling and transport. But is plastic the best choice? What if a more sustainable and biodegradable material could replace it? Researchers have begun exploring hydrogels—squishy materials that can hold a lot of water—as alternative packaging materials. In this science project, you will make your own hydrogels from gelatin and cornstarch and investigate what ratio of… Read more

Comparing Different Types of Irrigation Systems

Science Fair Project Idea

Scientific Method

With heat waves impacting the world globally, many gardeners, farmers, and scientists are turning to passive irrigation systems that reduce fossil fuel emissions while keeping plants well-watered and alive in the sweltering heat. In this science experiment, you will compare and contrast the effectiveness of passive irrigation systems compared to traditional surface irrigation systems and their impact on overall plant growth.

Cricket Wicket Knockdown Challenge

Science Fair Project Idea

Scientific Method

In this cricket-inspired engineering challenge, you will build a machine to launch a ball and knock down a target (called a wicket). How many times can you knock down the wicket in three minutes? Teachers, lesson plan versions of this challenge are also available. Read more
