Last week the kids and I did a fun activity we have never tried before. I saw something similar on the internet, and tried to turn it into a simple science experiment for the kids.
I spread out a layer of old baking soda onto a cookie sheet and then filled mini muffin tins with a small amount of white vinegar. I added food coloring to the vinegar and made a few different colors. One drop for red, blue, yellow and green, and a half of a drop (done by using a tooth pick) of each color I used when I was mixing colors. We put on some of the kids play shirts, and went at it. When the vinegar is dropped onto the baking soda with a dropper it sizzles and bubbles.
Later, I offered to give the kids a little pile of flour and had them make hypotheses about what would happen. Would it sizzle and fizz like the baking soda?
They absolutely loved it and spent almost an hour playing quietly. I was having so much fun watching them that I did not realize how much video I had shot. Instead of editing it too much, I just decided to put it all up (thank you to Hubs for all the help). I am pretty sure most of you do not want to watch this much footage of the tots doing this activity, but I thought some other little ones would have fun watching along. I know my children LOVE to watch footage of other children doing anything.
