Bioprinting: 3D Print with Living Cells! No 3D Printer Required.

Science Fair Project Idea

Scientific Method

Do you get excited about 3D printing technology? Do you like to think about other applications for this technology? 3D printing techniques can also be used with living cells, a method called 3D bioprinting. In this science project, you will explore 3D bioprinting a gelatinous substance with plant seeds. This process is similar to real 3D bioprinting techniques being explored to create tissues and organs. Read more

If you have ever watched a rocket launch on TV, you might have noticed that rockets have multiple stages. Some parts of the rocket fall off and burn up in the atmosphere whereas the rest of the rocket keeps going. Why does this happen? Try this activity to find out and build your own two-stage rocket using balloons! Read more

Build a Voice-Controlled Lamp

Science Fair Project Idea

Engineering Design Process

"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

Building the Tallest Tower

Science Fair Project Idea

Scientific Method

Skyscrapers are impressive structures. What does it take to design a building so tall? Engineers use strong materials and innovative design to push the limits of gravity. They use special tables to simulate earthquakes and test models of their buildings. In this project, you will build your own earthquake table and see how tall you can make a tower out of LEGO® bricks. You can even measure how hard your earthquake table shakes using the accelerometer of your smartphone and a sensor app. Read more

Can Plants Stop Soil Erosion?

Science Fair Project Idea

Scientific Method

Soil erosion can cost the world billions of dollars every year by washing pollutants into our streams and rivers and by causing the loss of farmland. What can you do about this problem? Help save the world (and some money!) with nothing more than a few plants! Read more

If you could choose to be an animal, would you rather be a predator or prey? For prey animals, survival in the wild means a daily struggle to escape potential predators. Predators, on the other hand, have to work very hard to make a catch. Some prey animals have evolved clever strategies to protect or defend themselves against predators. One common strategy is camouflage. Camouflage allows animals to blend into their surroundings so predators can't see them. Will this strategy increase an… Read more
