Today, the grade 7s were learning about different scientific properties and they were seeing what happens when dry ice and water are mixed together in a closed container (spoiler: the pressure builds until the container explodes). We went outside to watch, from a safe distance of course!
The top picture shows the plastic water bottle that is about to explode (not easy to see in the photo).
Here we are watching
another bottle
Then we moved to another section and watched what happened when another bottle was submersed in water. It was difficult to take a photo, but I did take a video. I have posted it below but I'm not sure it will work here (?)
