Children will use tools to measure and record amounts of rainfall over a period of two weeks. Ask children whether it's possible to measure the amount of rain that has fallen.
Offer children a coffee can to collect rain samples.
Place the can on your playground, and on the day after a rainfall, bring it inside to measure how much rain fell. Stand the craft stick or ruler in the can, and ask children to think of different ways they might measure the rain. If they need help, suggest that they mark the top of the wet section of the stick or ruler with a marker. Now ask children how they can record the rain measurement. Or let the children cut a bar of the same height out of construction paper and paste it on the paper.
