My parents gave Zeke a science kit for his birthday last month. It’s for kids older than him, but my dad had a plan.
He said he’d do the experiments with Zeke. I think it was mostly because he wanted to do them himself and grandfather-grandson bonding time was the perfect excuse.
The kit stays in my parents’ room and only comes out when they are going to do an experiment. They have a lot of fun together doing them. Best birthday gift ever!

We made a seismograph using a cup, string, box, and pen. Then we made “earthquakes” to see how it worked.
We put clay in one paper towel cover toilet paper tube and sand in another. Then we pushed into the clay and sand to try to push it through the paper towel. The clay pushed right through while the sand absorbed the pressure (that is until Adrian stuck his finger through the paper towel so he could see the sand all drain out).
Sand vs. Clay

We learned about the layers of the earth.
We demonstrated how waves travel through air vs. something solid and how that helps us know which layers of the earth are solid and which are liquid.
We used heat (from friction) to cause a top to “bounce” on a very cold bottle.
We used a hard-boiled egg to demonstrate the layers of the earth.
We used a hard-boiled egg and a raw egg to show how the earth wobbles as it spins like the raw egg does because of the liquid inside.

We learned how a Newton’s Cradle works and played with one.
More Newton’s Cradle
We dropped two balls, a small one on top of a big one, to demonstrate how the energy in the big ball (that hit the ground first) magnifies the energy in the small ball.
