Instructional Ideas
- Before the video, show pictures of worn headstones or statues and ask pairs to explain how these stones have been worn down over time
- After the video, have learners tweak their answers, incorporating more chemistry into their explanations
- Incorporate a PBL where learners research coal-burning power plants, their effects on the environment, their numbers in the U.S., their contribution to greenhouse gases, and their requirements in order to burn coal cleaner
Classroom Considerations
- Must have a computer, Internet access, and projection system
- This video is hosted on YouTube
Pros
- Video shows application of chemistry concepts through burning coal and acid rain formation
- Resource creates connections between math and science (both chemistry and environmental science)
- Video challenges students to do further math on their own
- Offers simple explanations with supporting examples learners can see in their everyday lives
Cons
- At 9:50 in the video, it poses a question and states, "The answer is in the comments below." There is inappropriate language within some of the comments so do not scroll through them in class; pull the answer from the comments and post in the room
