Have you ever done the rainbow milk experiment before? It's really neat, even for adults! Forever ago, I worked at a school that had mini sessions on a wide variety of topics every Friday afternoon for a month. Students signed up for the course they wanted to take and went to see that teacher all four weeks. I worked with kinder and firsties in a session called Rainbow Magic. In my search for activities, I came across the milk experiment and have done it every year since!
Clearly, I can't just be making rainbow milk for no purpose and since I most recently taught second grade reading, I connected it to procedural text! It's a whole lot more fun to read procedural text when you actually get to follow the procedure right?
Super simple to do and you can even have the kids easily do it in groups. All you need is some milk, dish soap, food coloring, and a shallow container. I've found school cartons of white milk and cheap aluminum pie plates from the dollar store do the job.
Add some drops of different colored food coloring to the milk. They shouldn't be touching, but not super far apart either.
Add a couple drops of dish soap to the milk near the food coloring and the colors will start to spread and mix together like a rainbow. The kids always like to continue to shake it up, but be careful because it will quickly turn brown.
I thought I'd share this now because it would be a fun activity to do around St. Patrick's Day (rainbows!). Click on the image below to download the article with the procedure listed for students to follow.
