CuriosityCube

The Millipore Sigma Curiosity Cube visited the Cleveland area for three days. They spent a day at Benjamin Franklin Elementary and a day at Cuyahoga Heights Elementary, then rounded out their visit with a stop at the Holden Arboretum. The Cube is a STEM lab in a shipping container. They travel across North America and stop in places where they have offices/facilities to do some STEM lessons with schools and the community. They also have one in Europe. An education specialist travels with the cube and scientists from the local MS facility also help with the lessons. Here is their 2022 Tour schedule. They work on lessons and logistics from December to about February, then get back on the road.

As part of the Millipore Sigma  Employee & Community Engagement program, they have Curiosity Labs , where scientists and engineers give back to their community by bringing hands on, interactive science lessons into the classroom. All lessons are developed with Life Science employees and education experts, aligning to the Next Generation Science Standards. Their target audience is students ages 8-13, but can adjust that.

These are some of the recent in school experiments that they have done. 

They also have Curiosity Labs at Home , a website with some easy STEM experiments to do at home. 

All of these excellent STEM resources are free. The webpages of experiments are available to everyone. The Curiosity Cube and site visits by scientists are only available if you are near a Millipore Sigma facility.
