Volcanoes are more exotic for me. #shouldalookedahead
I've never so much as even seen a volcano IRL. (Yes, I just said IRL in a blog post. And I'm 34. But, hey, I just learned what this stands for last week and I'm super proud of my hip self. Also, I might be going a little stir crazy this afternoon. #InRealLife)
The closest thing to an IRL volcano I've experienced is the baking soda and vinegar kind.
That activity never gets old for me. I love it every time. And so do the kids.
But for second graders, I wanted to "beef" up this activity some. Many kids start seeing this demonstration as preschoolers so I didn't want this to be the same ol' experience. But mainly, I wanted to make this more of an experiment and have something to test.
And since our focus during this landforms unit is to observe changes to landscapes and landforms, I wanted to tie the experiment in to that idea.

Volcano Set UpFor this experiment, you will need...
*empty water bottles with the bottom half cut off
*cups to pour
We used the top half of the water bottle as the volcano structure. We built a volcano mountain around the bottle with the play-doh. The volcano will sit on top of the paper plate.
Feel free to add "buildings" with brown M&Ms or lakes with blue M&Ms too if you like.
But most importantly, don't forget to sneak and eat a few M&Ms. Trust me, the experiment isn't as fun if you don't eat the treats! :)
Volcano Predictions & ObservationsOnce the volcanic landscape is built, we predicted the effects. We drew a picture of what would happen when the volcano erupted. Specifically, we talked about the forest. Would it survive?
Then, we put a spoonful of baking soda inside the water bottle...
and poured red vinegar into the water bottle slowly and observed the effects.
We recorded our observations.
Volcano EffectsThe fun thing about doing several volcanoes during your science block is that you can compare everyone's volcano effects. Give the students time to walk around and observe everyone's effects. Not everyone's forests will be destroyed. So, this makes a great conversation.
Why were some trees saved? Why were some forests completely destroyed?
After our discussion, we wrote down our conclusions about how and why our landscape changed.
You can find this science lab, plus much more science and STEM challenges in this landforms unit.
