Instructional Ideas
- Extend the lesson by having learners calculate sample dilution problems or in lab
- Support vocabulary by placing new words on a word wall with definitions and examples
- Stop video frequently to discuss new words, concepts, and ideas; place learners with a partner or in small groups for discussion purposes
- Soak dirty clothing in soap in a beaker and have learners explain how laundry soap removes stains
- After the video, have learners explain why some stain removers have the prefix oxi- in their names
- To assist English learners, post Spanish cognates on word wall, on front board, or in their notebooks
Classroom Considerations
- Requires access to the Internet, a computer, and projection system
- Learners must use newly acquired vocabulary in their discussions, in their notes, in their labs, and when sharing with the class
- This video is hosted on YouTube
Pros
- Video explains how and why solutions mix (or don't) and how stains are removed from clothes
- The resource explains why sports drinks are called electrolytes — something most pupils recognize and likely drink
Cons
- Video moves quickly through some major concepts — solutions, dilutions, electrolytes, molarity, and molality; some pupils may have a hard time keeping up
