This week we have been diving deep into physical and chemical weathering. We are using experiments to lead our discussions and have utilized several sources to learn about diverse ways that physical and chemical weathering occurs. In one experiment, students mimicked abrasion by putting several rocks in a tub with water and shaking it. The stones hit one another and broke down to create clay, sand, and silt.
In another experiment we got pennies and exposed them to oxygen to create copper oxide. We also made the connection to the Statue of Liberty, which is green because the top layer is copper, which has been exposed to chemical weathering.
