This week we had our very first experience with Four Winds! This program is brought to our class by parent volunteers and this year we're lucky to have two moms willing to visit each month! Thanks to Heather and Tammy for bringing the first workshop about erosion!
They began with a puppet show designed to teach the class about "agents of erosion"-air, water and gravity. Then we split the class into three groups for the three experiments. Heather had them pump air into a tray filled with beans, seeds and flour to see how even little puffs of air can move the items just like wind moves sand. Tammy had a tray with a little pile of flour and children took turns dropping straws filled with water over the flour to see how water can move and shape the land. My experiment had children shake a plastic jar with rocks and water as hard as they could! The shaking mimicked both gravity and water and their effects on rock. You'll see children looking into the bottom of the jar to see the tiny bits of rock they "broke" off when shaking! Thanks to Heather and Tammy and we look forward to future workshops!
