Instructional Ideas
- Add a viewing of this video to a high school chemistry unit on acids and bases
- Create a worksheet/note-taking guide for students to complete as they watch the video
- Flip your chemistry classroom by assigning this video as homework, performing a lab in class the following day to reinforce the content
Classroom Considerations
- This video assumes the class is familiar with using ICE tables to calculate the equilibrium constant for chemical reactions
Pros
- A practice problem allows students to apply their learning at the end of the video
- Presenter writes as he speaks, helping to visually support the content being taught
Cons
- Video is a little dry and may not capture the engagement of all students
- The presenter's handwriting is a little sloppy, but still legible
