Instructional Ideas
- Tally each group's hypothesis on the board; after the activity, have each group explain why their hypothesis was or was not correct
Classroom Considerations
- Activity assumes scholars have an understanding of pH and conductivity
- Video link in resources is incorrect; the correct link is: www.youtube.com/watch?v=N9S3oC7Oui8
- Activity best fits middle school or lower level high school classes
- Resource requires pH and conductivity meters
Pros
- Activity provides simple lab worksheets
- Classes may complete the lab by either watching the video (link found in classroom considerations) demo or completing it in class
Cons
- None
