Popcorn Physics with my Pre-schoolers

As we were eating our bed time snack this evening, I started asking my kids about why popcorn pops.  My son said, " I don't know."  He was interested though, so I explained that the kernels had water inside of them.  I asked whether the energy was going in or coming out of the popcorn.  (It's going in.)  I explained that the energy going in changed the water from a liquid to a gas.  We examined a popped kernel to see where the seed coat ended up.

Then my son had a better idea.  


  1. We did another popcorn experiment, soaking the kernels in water and oil and it was interesting to see what happened to them for that.

    Thanks for linking up to Science Sunday!

    1. Oh, we will definitely have to try that too!
