- Lesson assumes high schoolers already understand conservation of mass, chemical equations, and converting between units
- Must have a classroom computer, Internet access, and a projection system to use the lesson
- This video is hosted on YouTube
Pros
- Video relates stoichiometry to trying to determine how much sugar to put into a cup of tea to make sweet tea
- Relates complex concepts to high school students, keeping them engaged and cementing the material
Cons
- The video is very detailed, heavy with information, which might require you to explore and extend the lesson further in the lab and classroom
