Weathering is the process of disintegration (physical) and decomposition (chemical) of rocks. Weathering is a process of breaking down rocks into small particles such as sand, clay, gravel and other fragments. There are two types of weathering: mechanical weathering and chemical weathering. This activity will allow learners to differentiate physical changes from chemical changes. Learners will follow the following instructions: 1. Prepare the needed materials: two pieces of paper and match. 2. Tear one paper, observe, and record your answer. 3. Burn the other paper (with teacher supervision), observe, and record your answer. 4. Based on your observation, differentiate the changes after tearing and burning.​
