Teaching activities for use with the SEM

The scanning electron microscope lets us see the surface of three-dimensional objects in high resolution. The images that we see can be quite different to what we experience with light microscopes.

Use these teaching activities prior to the SEM’s arrival so that students become familiar with the types of images they are likely to see. Alternatively, use them to lead discussions or engage students during small-group rotations when using the SEM.

While observing the images, ask questions regarding the artefacts they see in the slideshow or matching activity. Encourage students to justify their answers using evidence.

• What is the artefact’s shape? How might this help you identify it?

• Does it have repeating patterns? How might this help you identify it?

• Is the sample two dimensional or three dimensional?

• Do you think the artefact was living or non-living? Why? What clues are you using?

• How might you group artefacts with common characteristics?
