Science Fair Project Idea
Did you ever have a favorite toy like an action figure or doll that could light up, make noise, or move? This project will show you how to make your own interactive toy using the Science Buddies . Check out the video to see what this simple, but fun, project looks like. The version you make does not have to be a robot; it can be any shape and have any sound effects you want. This project uses a tiny computer called a Raspberry Pi and is fun and easy for even complete… Read more

Science Fair Project Idea
Water is a valuable resource, and water shortages are a serious problem in many parts of the world. The problem can be made worse by people who waste water; for example, by watering a garden or using sprinklers on their lawn (or a farmer taking care of an entire field) when it has rained recently or the soil is already moist. How can you help conserve water and prevent such waste? One way is to build an electronic soil moisture sensor. This project will show you how to build a circuit that… Read more

A nice hot cup of tea sure can wake and warm you up in the morning. In this project, you will investigate the chemistry of tea. The longer you steep a tea bag in hot water, the stronger the tea will be. But how does the strength of the tea change with longer brewing time? In this project you will make a very simple electronic device to measure the strength of tea. The device will determine how strong the tea is by measuring the amount of light the tea absorbs.

You have probably read all about forms of alternative energy like solar and wind power. But what about human power? With the aid of a coil of wire and some magnets, you can generate electricity with nothing more than a flick of your wrist. In this project, you will build a small hand-powered electrical generator that can power a series of tiny lights. Get ready to save the planet and get some exercise at the same time! Read more

Safety

Neodymium magnets are very strong and can pinch your fingers when they come together. You should keep them away from pets and small children because they can cause serious harm if ingested. As with any magnet, you should keep them away from computers, cell phones, and credit cards.

Adult supervision is required when using a hobby knife.

Science Fair Project Idea
What do pizza, milk shakes, and ice cream sundaes have in common, besides being delicious and loaded with calories? You might be surprised to learn that these foods, because they contain dairy products, cannot be eaten by the majority of people around the world. Dairy products contain the sugar molecule lactose, and the majority of people on the planet slowly begin to lose the ability to digest lactose after the age of 2. In this human biology and health science fair project, you will… Read more

Science Fair Project Idea
What can you do with a bucket of soil? You could use it to grow some beautiful plants and vegetables—or you could use it to produce electricity! Surprised about that? You actually can power electric devices with just mud! Are you curious about how this works? You need some little helpers in the soil—bacteria—that are able to turn their food sources within the soil into electricity in a device called a microbial fuel cell. But is this possible with any soil and does the soil… Read more

You may have seen movies or read books where armies in medieval times catapulted large rocks or other objects at castles (or each other!). These armies used different types of catapults to accomplish different goals — for example, launching things over or into castle walls to knock them down. In this experiment, you will use a ping-pong ball catapult to lay siege to a "castle" and find the right settings to hit your targets. Read more
