Going along with the anatomy lesson we did yesterday, today's Pinterest activity was a cerebrospinal science experiment.
The boys really liked this one! The 9 year old and 6 year old were both really interested in it and enjoyed trying different ways to shake around the unprotected "brain". They tried doing jumping jacks with it, skipping, "acting crazy", and then dropping it from different heights to simulate a fall. We weren't able to break, or even crack, the egg but I also didn't let them drop it from higher than 4 feet since the cover wasn't super secure and I didn't feel like cleaning up splattered egg today. But there was a lot of brain rolling around and knocking into the sides of the skull so they got a good general idea.
They were quite amazed by how well Mr. Egghead was protected by the water being added. They tried all of their same activities and were literally open mouthed with how different it was with the water there to cushion the jostling around. We talked about what it would be like if we didn't have cerebrospinal fluid to protect our brains during activities like wrestling with their dad, playing football, exercising, or falling.
This one was a hit!
