 Unit 3: Earth's Crust Activity 7: Whether It Weathers - Chemically? (SI GLEs: 6, 7, 8, 11, 12, 19, 22, 23; ESS GLE: 14)
CC: Students are to let the beaker and the copper both stand undisturbed overnight. The next day, have students observe the beaker and the copper and record their observations in their table.
CC: To link Activities 6 and 7, have students complete a Venn diagram to compare and contrast mechanical weathering and chemical weathering. After completion, have students do a quick "round robin" where each student cites one similarity or one difference. Venn diagrams could be posted for display. |
