Colored ice

Materials required:

- Ice cube tray

-Water

- Tray

- Spoon and eye dropper

The day before put water in your ice tray with a few drops of food coloring. Put it in the freezer until you are ready to play.

The next day, put some salt in a bowl, on a tray add the polar animals and the ice cube.

We used primary colors, red yellow and blue so we can the colors mixing when the ice melt and learn that blue and yellow makes green, red and blue makes purple and yellow and red makes orange.
