These days, STEM learning is more important than ever. Science, technology, engineering, and math are the keys to many modern careers, so a good grounding in them from an early age is a must. The best STEM activities for kids are hands-on, leading students to cool innovations and real-world applications. Here are some of our favorites, with challenges and experiments that will really get kids thinking about how STEM plays a part in their everyday lives.

8. Engineer a helping prosthetic
Prosthetics are special devices that help people who are missing a body part, like an arm or a leg. They act like a replacement for the missing part, helping the person to move and do everyday activities. Engineer a paper hand to simulate how a hand moves and how a prosthetic might be designed and built for those who are in need of this tool.
9. Understand the importance of water
Learn how water moves and is recycled throughout the Earth with the water cycle. Teach students what the water cycle is using these Google Slides and worksheets we put together. Then, have students draw the cycle with permanent marker on a ziplock bag. Add water with a few drops of food color, hang in a window with sunlight, and make observations for a few days and notice how the water moves and changes.

11. Build a bottle rocket
Build a bottle rocket, and learn how molecules act under pressure when applied to launching a rocket. Connect this with Newton’s 3rd law of motion and how every action has an equal and opposite reaction. Connect with watching rockets being launched by NASA and how the same concept is applied as they are being sent up into space.
12. Understand how volcanoes erupt
Using volcanoes, learn more about Earth’s processes and how they change. Teach about the different types of volcanoes and where some are still active here on Earth (e.g., Hawaii, Italy, Indonesia).
