Science Day with 2B

We created homemade lava lamps and talked a little about density. We stacked different liquids of different densities on top of one another in a bottle with different colours. 


We filled our bottle with water and oil. Then we placed a few drops

of food colouring in it (to see the “lava” better) and some glitter for fun. We discussed the density of oil hanging out on top of the water before we put in the Alka Seltzer. It was amazing watching the large bubbles rising and sinking.
