Materials
Several cardboard tubes – toilet paper rolls, paper towel rolls, gift wrap tubes, etc.
Tempera paint – we used blue and yellow
Paper plates
Large white construction paper
Tape
Directions
Tape the paper to the table. Pour a different color paint onto each paper plate. Invite your child to dip the cardboard tube into the paint and then make a circle print on the paper. Allow your child to continue exploring covering the paper with circles. Observe what happens when yellow circles are printed on top of blue circles. What new color circles can be seen? Display once the paint has dried.
