Nano Interactions

Tiny particles can provide big learning opportunities! Middle school scientists explore the world of nanoparticles through reading, discussion, and experiment. Collaborative groups first apply nanotechnology to determine water hardness. They then design a method to reduce the number of particles in suspension.

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
  • This resource is only available on an unencrypted HTTP website. It should be fine for general use, but don’t use it to share any personally identifiable information

  • 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

  • None
