Science boxes with five days’ worth of themed STEM activities and science experiments for kids delivered right to your front door!

COSI Connects Kits - Science boxes with five days’ worth of themed STEM activities and science experiments for kids delivered right to your front door!

Check out COSI’s CEO Dr. Frederic Bertley as he takes to the ice along with the Columbus Blue Jackets in the Science of Hockey edition of COSI's Science of Sports video series. These hockey-themed short videos and COSI Connects activities illustrate the intersections of science and hockey through topics such as the physics of a slap shot and the chemistry of how a Zamboni operates.


Newton's Third Law states that for every action, there is an equal and opposite reaction.

Isaac Newton probably would have been a fan of hockey. Why? COSI's CEO Dr. Frederic Bertley explains.

In the Connects activity, you will use that principle to make a balloon powered pinwheel!

Do you know how science helps keep the ice in a hockey rink nice and smooth?

COSI's CEO Dr. Frederic Bertley explains in this video featuring a Zamboni.

In this Connects activity, explore why frost forms. Then create your own frost using a solution of ice water and salt in a glass.

How exactly do the those thin skates glide across the ice?

COSI's CEO Dr. Frederic Bertley explains how friction and pressure causes the ice on a hockey rink to melt directly under the blade of a skate

In this Connects activity you'll explore liquids, solids, and physical changes while you make a sweet treat. It just takes a little bit of work and a little bit of science to make homemade ice cream!
