Little Scientists

Is there anything better than seeing a child's eyes light up as they figure out the solution to a vexing problem? We make it fun, but hard, and the challenge is what keeps them coming back for more.

Real Experience

Engaging young students in science encourages them to think logically through their problem solving. Early childhood science truly helps in developing an inquisitive mind.

Motivated Learners

The best method of extending a child's boundaries of knowledge is to allow them to pursue their passion and for you to support their interests.

Increased Vocabularies

We don't just read words to read words, but to go to magic lands, learn history, and investigate mysteries. Kids learn language when they are engaged in authentic learning, like scientific inquiry.

Math Geniuses

Engaging students through a blend of science, technology, engineering, art, and math yields the ultimate learning experience. Concepts are grasped faster, easier and more completely

Empowered Learners

We know science can be hard to teach, but we've provided you the tools: activity sheets, in depth labs and step-by-step video instructions to make it as easy for you as it is fun for them.

Inspired Science!

"Solid research based science activities to inspire the next generation of scientists"
