I took a Ziploc bag and put blue finger paint on one side and yellow paint on the other side. I sealed it good and gave H a Q~tip to move the paint around. She used her hand as well. We talked about what we thought would happen to the colors when they mixed. Once it was mixed she started to use her fingers and Q~tip to draw and to write letters. she loved practicing writing letters in the bag. We made hand prints and pictures in the bag. Then we talked about if you could see through the bag and if it was translucent, transparent or opaque.Then we talked about examples of things that were all of the different types. She has asked me to do this project over and over.
