We talked a lot about colors and rainbows during our St. Patrick's Day theme, especially green. A fun science activity is showing the kids how to make green by mixing yellow and blue, and a delicious way to do this it with food! It's a pretty similar activity we did with our squish bags, but much tastier!
This is an idea that I borrowed from a great blog called Little Fingers Big Dreams!
Basic concepts- full/empty, more/same
First, we gathered our tasty ingredients-vanilla frosting, food coloring, graham crackers, plus 2 clear bowls, a spoon.
Next, we made some yellow frosting by putting food coloring in (we even snuck in a quick counting task by counting out 5 drops!)
Same with making the blue frosting.
Then the students requested a plate ("I want a plate") and a graham cracker ("I want a cracker"). [And, what shape is a graham cracker?--a rectangle! sneaky way to talk about shapes ;)].
More requesting--"I want blue" "I want yellow" "I want a spoon"
Then, we all got to mixing--yellow + blue = green!
The best part--eating the green!
