Students investigate how climate affects the rate of weathering. Students will be focusing their experiments on chemical weathering to see how temperature affects how quickly an alka seltzer will dissolve. Students will come up with 4 tests to determine how temperature affects the rate of dissolution.
Materials - (per group)
• 4 alka seltzers
• clear plastic cup or beaker
• waste container or access to sink
(For the class to have access to)
• Hot water
