How to make snow
Mix together 3 cups baking soda and ½ cup hair conditioner, preferably white so that it looks like real snow.
Kneed it together and than you will have snow!
Antarctica small world
Children learn through active exploration. Set up some animals that live in the snow with some ice.
Lay out some books next to the play for the children to look through and investigate.
Ice
There are so many science experiments that include using ice. A good one that would follow nicely from snow is to make rain. To do this you need to heat some water until it is steaming. Pour the hot water into a jar so that it is about a third full. Put a plate on top of the jar. After a few minutes put some ice cubes on top of the plate and watch closely to see what is happening inside the jar.
