Instructional Ideas
  • Preview video in order to scaffold information for learners 
  • Choose stopping points in the video and script questions and problems for learners to discuss and solve in pairs
  • Follow up with labs and activities to support complex concepts discussed in class
Classroom Considerations
  • 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
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
