Phase: | During/Explore/Explain |
Activity: | The students will watch an EdPuzzle video about Weathering. The teacher can share the link via Google Classroom if desired. The students will complete a weathering lab in the chemistry, biology, or physics lab or science classroom. Chalk is a type of limestone made of the shells of tiny organisms. When you write your name on the chalkboard or draw a picture on the driveway with a piece of chalk what happens to the chalk? It is mechanically weathered. This experiment will help you understand how chalk can be chemically weathered. |
Assessment Strategies: | The students will complete a 3-2-1 essay that includes three things they learned about weathering, two factors that affect the rate of weathering, and one example of weathering. |
Advanced Preparation: | The teacher will need to make copies of the handout. The teacher will need to create a free Edpuzzle and Google Classroom account. The teacher will need to reserve a science lab at their school if they can not complete the lab in the classroom. The teacher will need to purchase the materials needed to complete this lab. All labs should have a variety of beakers on hand. Materials

Variation Tips (optional): | The teacher may use any other Edpuzzle video related to weathering or may edit the video to insert questions related to the video. |
