Hello, parents of curious-minded children!

At The Great Courses, we believe in lifelong learning. And, we believe this pursuit can (and should) start in childhood. To that end, we’ve developed a series of Science Experiments for Kids based on a STEM curriculum and designed to generate creative thinking in the fields of science, technology, engineering, and math. Our goal is to provide free resources that will help children gain hands-on experience in how these concepts relate to the real world.

We encourage you and your children to check back here on a regular basis as we will continuously add new science experiments, art projects, math riddles, and other fun projects.
