squishy human body

We have this squishy human body set and the boys love playing with all the organs! It can be a bit to tricky to put them all back into the body, though.

praying mantis kit

Grow Your Own Praying Mantis Kit:  We love doing butterflies and have even done ladybugs (which were a little on squeamish side for me). The thought of ants in my house, even if they’re contained, makes me squirm. But praying mantis’s take the cake for being the grossest insect to watch grow in your house. Blech.

  1. When I was a kid, when we did the egg experiment, we also put a chicken bone in each of the chemicals. By the end, we could literally bend the bone like rubber because all of the calcium leached out. It was a great explanation of why calcium is so important for our bones!
