Instructional Ideas
- Demonstrate the properties of ferrofluid to the class after viewing the presentation
- Bring examples of colloid and suspension solutions and incorporate them into the activity as an observation assignment
Classroom Considerations
- Create smaller working groups, as the activity is designed for stations
- Order the materials kit in plenty of time before planning to execute the lesson
Pros
- Grading is easy using the rubric in the teacher's guide; the guide also contains other printables
- Activity uses the real-world example of water hardness to help make nanoscience more relatable for younger learners
Cons
- None
