Throughout our dinosaur theme, I think the volcanoes captured the boy’s {I currently have all boys enrolled, mostly 2 year olds!} attention most.
They loved making mini volcanoes. I gave them each three containers: one with colored vinegar, one with backing soda and one empty bowl. Each had a spoon and a water dropper. I showed them briefly how they could put a little baking soda into the empty bowl and then drop a little vinegar into it. I just let them discover they could scoop larger amounts or pour the whole container. 
We did this activity two days in a row. They all loved it, even the two who are just 18 mos. I helped them of course. It’s a bit science, a bit sensory. Completely fun though!
The small containers are from The Dollar Tree. I resisted buying them at first not knowing exactly what I’d use them for but since having them, we’ve used them a lot. This is a perfect activity to do on trays.

We reccently did baking soda right on the tray and let them use eye droppers to drop primary colored vinegar onto their baking soda letter. They loved it! Even Trent did it! :-P
