Instructional Ideas

• Encourage the class to research each of the products demonstrated prior to doing the activities with them

Classroom Considerations

• Pupils need to be familiar with nanotechnology and its applications
• You will need to gather the materials for the demonstrations and, in some cases, make them
• The third in a six-part series

Pros

• Includes background information about each of the nanotechnology materials used in the demonstrations
• The demonstration directions come with questions 

Cons

• None
