In this unit designed for kindergarten classrooms, children participate in activities about wet and dry materials. These experiments explore evaporation, texture and different solutions. Some of the experiments are done in stations.
Here is how a selection of these activities could become a week-long unit of study in a kindergarten classroom:
'Itsy-Bitsy Spider' is a great song for this unit!
'Make a Rainstorm' is a fun circle game. Start by having the children stand in a circle. The leader walks around the inside of the circle, doing a certain action. The children copy the action as the leader passes and continue doing it until another action comes along. To build up a 'rainstorm', do these actions: start by rubbing hands together, then gentle claps, then louder claps, then drum the knees, and finally stomp the floor. To make the rainstorm die down, reverse the order of the actions until it's just the leader walking quietly again!
Sample wet and dry snacks! Try different kinds of water (soda water, mineral water, bottled water, tap water). Can you tell the difference? Also try cookies or crackers dipped in milk or juice.
Definitions for kindergarteners:
dry - Not wet.
absorb - Soak up or "drink", like a cloth soaks up and holds water. When something absorbs water, it gets wet.
evaporate - When water seems to dry up or disappear and go into the air.
solution - A mixture or something dissolved or broken up in water or another liquid.
texture - How something physically feels, i.e. soft, bumpy, smooth, etc.
pressure - The act of pressing down on something, or how much pressing there is.
