We started this activity by putting water in clear cups, and adding the primary food colors to each cup. We then worked together to mix the primary colors to make the secondary colors. Our green color didn't turn out great, but E loved seeing the transformation of the two colors into something new.
We then put the colored water into ice cube trays to freeze for the next activity. I tried to use the words "liquid," "solid," and "freeze" in this step.
The next day, we pulled one of each color of ice cube out of the tray to put back into the clear cups. We then took them to the bathtub to let the real fun begin!
In the bathtub, we focused on the ideas of "melting" and "liquid" once again as E played with the ice cubes. She loved chasing them around the bath until they disappeared completely. She also loved the sensory aspect of putting the ice cubes on her toes and feeling the hot and cold simultaneously.
