Spring SAVY 2014, Week 4 – Where’s the Beach? (Kindergarten)
We had another great day in SAVY! The students learned more about erosion by conducting several experiments to simulate wind erosion, water erosion, and sand erosion. With the help of a hair dryer and a watering can, we were able to better understand the erosion process over time. We discussed how human actions contribute to the problems of erosion and brainstormed suggestions for combating.
We completed a systems diagram for erosion. We included the elements, inputs, outputs, interactions, and boundaries. The students showed good understanding of erosion as a system.
At the end of the session, we took an initial vote for the camp proposal. The council members were asked to vote “for”, “against”, or “undecided” and to explain their reasoning behind the vote. At this time, four members are “for”’, four members are “against”, and two are still undecided.
Next week, we will research different alternatives to assist in preventing erosion. We will also explain the effect of natural and man-made forces on coastlines. We will learn more about jetties, sandbars, beach renourishment, and bulkheads. Researching these solutions will assist us in making recommendations for the camp.
- Walk around your backyard, neighborhood, nearby forest, etc. Look for examples of naturally occurring erosion and erosion caused by human actions. Why do you think each type of erosion occurred? Should any steps be taken to prevent any of the erosion in your examples? Why or why not?
