Put Science to Work & Engineer Amazing Projects

Innovators have the power to change the world.

Innovator working on a Eureka STEM box

Our crates are designed to inspire kids (and kids at heart) to think about the design and engineering behind the objects around them. With that lens, they can understand and question why things are the way they are and how they might be made better.

Eureka Crate provides a hands-on lesson in the creative and purposeful application of science and engineering principles in order to solve a real-world problem. By connecting their project to the design history behind it, kids can see themselves as part of an ongoing story of invention — and build the creative confidence to write the next chapter.

Eureka Crates are absolutely amazing! Idea and execution are perfect. So far my daughter built ukulele and lock box and were impressed by quality of both projects. Eureka Crate is now her most desirable gift for any occasion. Highly recommend!

My 12 yr old LOVES them and usually makes something he can use. Sometimes kids are too easy - he put them together in 30 min.

The product is of good quality (not cheap plastic or flimsy). Easy enough for the kids to follow the instructions and put together themselves.
