Baking Soda and Vinegar

This is a top ten science activity with my Kinders. It's super easy and there are lots of options and variations you can do with it. 

Supplies: vinegar, baking soda, food colouring, eye droppers, small containers, large tray or dish

First, pour the baking soda into the dish. You want to have a good layer of it, 3-4 cm at least. Next, put vinegar in the small containers and add a few drops of food colouring. Monkey chose blue and green. 

Now the fun part! Use the eye droppers to drop some vinegar into the dish of baking soda. The chemical reaction makes a fizzy noise and lots of bubbles! (It's actually forming carbonic acid which immediately breaks apart into water and carbon dioxide.)

Monkey loved this, but he needed a lot of help with the eye droppers. They are tiny even for his little hands and require a lot of concentration. Great fine motor practice! But it was easy to keep him at it because of the awesome reaction once he dropped the vinegar into the dish. 

Here is our final product, I love how it turned out - it reminds me of the Earth!

This is another great activity that can be thrown together in just a few minutes. We'll be pulling it out again for sure.
