Materials you will need:

• Short clear plastic cups
• Food colouring
• Pitcher to hold water
• baster or dropper (if you have one)

Invite your child to pretend to be the concession stand worker at the zoo or movies. Have them fill plastic cups with different levels of “soda” (coloured water) and then arrange them in order from least full to most full and then reverse the order. Add a baster or eyedropper to change the water level.

*Tip:  Place a tray or cookie sheet under the cups to catch any spilt water.
