Have you ever wondered why a water strider can walk on water? Or how detergent can clean your dishes? If you look around you carefully, you can find dozens of similarly interesting phenomena that are all linked to the surface tension of water. In this science activity, you will make a little toy raft that is actually powered by surface tension, and use your vessel to investigate how surface tension works!

The Mars Curiosity and Perseverance rovers use scientific instruments, nicknamed ChemCam (Figure 1) and SuperCam respectively, to help them analyze the composition of rocks and soil on Mars. You can learn more about these cameras from the resources in the Bibliography, and more about why scientists want to analyze rocks on Mars from the video on this page.
Figure 1. The two main parts of the ChemCam instrument on the Mars Curiosity rover.

Radio-controlled (RC) robots can explore places that are difficult or dangerous for humans to get to, like collapsed buildings after a natural disaster. They can use cameras and a variety of other sensors to gather information about their environment, like the presence of toxic gases or other hazardous materials. The robots can even use grippers and robotic arms to collect and safely dispose of some materials. You can build your own RC robot using the Science Buddies Bluebot kit, Electronics…

Motors are used in many things you find around your house, like your refrigerator, coffee maker, and even a lawn mower. In this electronics science fair project, you will get to build a simple motor, using a kit, and then test how the number of batteries (amount of voltage) used to power the motor affects its performance.

Light sensors are part of many devices that we use every day. For example, they help your phone know when to automatically brighten or dim the screen based on ambient light levels. They can also be used to help solar panels track the sun, which helps the panels generate more power. Many spacecraft and planetary rovers are solar-powered. In this project you will build and program your own solar-tracking robot. Optionally, you can add solar panels and rechargeable batteries. Can your robot keep…

Astronauts on Mars missions must be protected from hazardous environments, like steep cliffs, rocky terrain, and extreme temperature variations. How can geofencing help? In this project, you will design a system that uses geofencing technology coupled with biosensors to ensure astronaut safety. The system will create a virtual boundary around astronauts, providing alerts if they approach dangerous areas or leave designated safe zones, or if their vital signs fall below a certain threshold. Can…
