Fun science experiments to explore everything from kitchen chemistry to DIY mini drones. Easy to set up and perfect for home or school. Browse the collection and see what you want to try first!
Stop for a minute and try to imagine your world without electrical power and electronic gadgets. No convenient appliances in the kitchen, no electric lights. No computers, MP3 players, television, or video games. Your life would be completely different, wouldn't it? Electricity and electronics are so central to modern life that, paradoxically, they're easy to overlook.

| Build a Simple Electric Motor! Log in to add favorite More Menu
Science Fair Project Idea When you think of a motor, you may immediately think of a car, but you actually encounter other motors in your home every day. That's right, if you put on clean clothes from the washing machine, ate food from the fridge, or used a fan, you used an electric motor. In this electronics science project, you will make a simple electric motor with two magnets that "talk" to each other. As they interact, they will alternate between "liking" each other (pulling together), and "disliking" each other… Read more
Make an Automatic Pill Dispenser Log in to add favorite More Menu
Science Fair Project Idea Remembering to take medicine at the right time can be hard, especially if you need to take multiple medications at different times of day. It might not be a big deal if you forget to take your daily multivitamin, but for some people, forgetting to take medication at the right time can be dangerous. What if you had a device that could not only set off an alarm at the right time, but also automatically dispense the right pills for you? In this project, you will build an automatic medicine… Read more
Explore Optical Illusions: Build an Infinity Mirror Log in to add favorite More Menu
Science Fair Project Idea Do you want to trick friends and visitors with an amazing optical illusion? In this engineering design project you will learn how to build an infinity mirror,with built-in lights that make the mirror look like a deep tunnel with no end. But pick the mirror up and look behind it, and you will see that it is only a couple of inches thick! Read this project to find out not only how this illusion works, but how to design and build your very own infinity mirror from scratch. Read more
The Strength of an Electromagnet Log in to add favorite More Menu
Science Fair Project Idea You may be familiar with permanent magnets—the kind that hang on a refrigerator. But did you know that other magnets, called electromagnets, can be turned on and off? When turned on, electromagnets act just like permanent magnets, but if you turn them off, their magnetic properties disappear. Electromagnets are an important part of many electronic devices, like motors, loudspeakers, and hard drives. You can create an electromagnet with a simple coil of wire and a battery. In this project,… Read more

Is It Ripe Yet? Build a Circuit to Detect Ripe Produce Log in to add favorite More Menu
Science Fair Project Idea When you go to the supermarket, how do you pick out ripe fruits and vegetables? You might look at their size or color, or feel them for firmness. That might be easy to do when you pick out a half dozen apples, but imagine if you had to examine thousands of apples growing in a field, or strawberries coming down a conveyor belt getting ready for packaging. Suddenly, it is a lot harder to do yourself! What if a machine could pick and sort the produce for you? In this project, you will address part… Read more

STEM Activity 1 2 3 4 5 103 reviews What do you need to make a motor? Not much! In this quick activity, you will make a simple motor using nothing but a battery, magnet, and a piece of wire. Read more
Build Your Own Crystal Radio Log in to add favorite More Menu
Science Fair Project Idea Have you ever wondered how a radio can grab signals that are transmitted through the air and convert them into sound? In this science project, you will build your own AM radio receiver from scratch and use it to listen to AM radio broadcasts. With your crystal radio you will be able to experiment with the circuit and the antenna to get the best reception. Read more
Build a Voice-Controlled Lamp Log in to add favorite More Menu
Science Fair Project Idea "Alexa, turn on the lights!" Sometimes it is easy to take the technology around us for granted. But have you ever wondered how a smart speaker like an Amazon Echo® knows what you are saying and how it can control lights and appliances in your home? It can seem like magic if you buy a device that just works when you open the box.In this project, you will learn how it works. You will build your own smart home device to control an appliance with voice commands using an Arduino®. Get… Read more
Dealing with Diabetes: The Road to Developing an Artificial Pancreas Log in to add favorite More Menu
Science Fair Project Idea Imagine if you had to take medicine every time you ate, and you had to use a math formula to figure out how much medicine to take based on the nutritional makeup of the food, how you were feeling, and what activities you were planning to do. You might also need extra medicine throughout the day (even in the middle of the night) based on your blood glucose levels. People with diabetes who take insulin do this every day. They use finger sticks and blood glucose meters or a continuous glucose… Read more
