Color Mixing Activity

I teach science at Sydney’s preschool once a month, which is a fun way to get to know her little friends and be involved in her school. This month, we talked about colors which is great at this time of year with all the fall leaves turning. This is such a fun activity that my big girls begged to have a turn doing it when they got home from school.

Materials

  • zip-top sandwich bags
  • white shaving cream (the cheap stuff)
  • red, blue, and yellow food coloring
  • tape: masking or packing (optional, but highly recommended)

Try it out

Squirt a good-size blob of shaving cream into a bunch of different bags–at least one bag for each child, or three for each if they want to try all the combinations. Aim for an amount about the size of two golf balls.

For green, drop three drops of yellow food coloring on one side of the shaving cream and one drop of blue on the other side.

For orange, use three drops of yellow and one drop of red.

For purple, use one drop of red and one drop of blue.

Try to keep the drops of food coloring separated, so your kids can see the clear difference between the starting colors.

Squeeze the excess air out of the bag and zip it up. Further seal the top of the bag with tape. The tape is really just to remind the kids not to open the bag, I don’t know how much it really keeps the bag closed.

Have your kids rub and squeeze the bags (gently!) until the colors mix and combine.

So fun!


Have you done any fun activities with your kids lately?
