Solids, Liquids, and Gases… Oh My!

We are in the homestretch – only 3 more days left until summer!

I’m gonna be real honest here. I did not have any lesson plans for this week. I had activities printed off and crafts prepped we could do, but I knew I needed something more engaging.

Since we’re a STEM school, I thought it would be fun to focus on a science topic we hadn’t gotten to cover this year – states of matter.

We began with this fun video from Harry’s Kindergarten on Youtube:

We also read this book together as a whole group and brainstormed through the writing portions:


{This wasn’t the best example of our brainstorming, but that’s ok!}

This is a freebie from Once Upon a Classroom.

And of course, it wouldn’t be right to end the morning without making oobleck!


To make your own oobleck:

  1. Add 1 part water to 1.5-2 parts cornstarch.
  2. Use your hands to mix them together. The subtance should feel like a solid, but begin to melt when in contact with the heat of your hand. If it does not melt, you may need more water. If it stays a very runny liquid, you may need more cornstarch.
  3. DO NOT pour this down the sink!!!! It WILL clog your drains. Thankfully, it scrapes off tables and bowls easily and turns into an almost-powder. Washing the excess off is finethen.

It was a big ol’ mess in our room, but a lot of fun! Not bad for some last minute planning.
