Science Buddies' kindergarten science projects are the perfect way for kindergarten students to have fun exploring science, technology, engineering, and math (STEM). Our kindergarten projects are written and tested by scientists and are specifically created for use by students in kindergarten. Students can choose to follow the science experiment as written or put their own spin on the project.

For a personalized list of science projects, kindergarten students can use the Science Buddies Topic Selection Wizard. The wizard asks students to respond to a series of simple statements and then uses their answers to recommend age-appropriate projects that fit their interests.

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
