This lesson will be used as to assess student knowledge of size or SI prefixes and which equipment/tools you would need to view objects of particular sizes. The lesson can be used to see how much students know before teaching; to introduce them to the topic; or to assess what they have learned after teaching about size and SI prefixes. The concept of size and scale is important for students to learn so that they can understand how small the nanoscale is – objects between 1-100 nanometers.
