We have done a lot of Science activities this week to try to finish our Liquids/Solids unit before the break.
We made boats out of recycled materials. We thought back to previous experiments (e.g. float/sink, absorption, etc) to help with planning what materials to use. Some of my students got stuck on the fact that although the cardboard items DID float (some of them), they wouldn't be a good material for a boat over time.

(Testing the boat to make sure it floats!)
Then we made sparkle jars! We added oil and water to a plastic bottle (they remembered that oil and water do not mix, from one of our experiments). We also added small beads (float/sink experiment), food colouring, and sparkles!
I put hot glue around the bottle lid before sealing it to try to prevent the water bottles from leaking. These were a huge hit! The kids loved shaking them up and then watching everything settle in the bottle. It was really sunny outside today so some of them held their bottles up by the window to watch the sun shine through them :)
