Last week we did a fun activity focusing on absorption and color mixing. We used 3 cups, 2 paper towels, food coloring and water. We first talked about absorption and how we can use things like paper towels to absorb water. We demonstrated absorbing spilt water, and how we are able to remove water from paper towels. Next we set up our experiment. We lined up 3 cups, put water in the cups on the end and left the middle cup empty. I explained how we were going to put one end of the paper towel in a cup that has water and place the other end of the paper towel in the empty cup.
We decided to add food coloring to the water to make it easier to see the water being absorbed and to see if we could get the colors to mix.
Here is what our cups looked like after about 10 minutes.
Stay tuned for more color and rainbow activities!
