Big ideas

Learning Sequence

Show all resources
  1. Welcome students to the second lesson and encourage several new students to introduce themselves to the class. Review the big ideas of previous lesson on the historical development of optical microscopes and their uses.
  2. Investigation – Students view the YouTube clip on the operation of Atomic Force Microscopes (AFM). Resources
  3. Discussion – What are the limitations of light microscopes – magnification or resolution? How do these limitations affect our ability to visualise/resolve objects on the Nano-scale? What size objects can we resolve/not resolve? Students then view the YouTube clip on the Scanning Tunnelling Microscopes (STM). Resources
  4. Investigation – Students to investigate and discuss the scanning probe tutorial available at the Beckman Institute for Advanced Science and Technology. This to be preloaded on the studio computer for students. Resources

  5. Collaboration – Students to compare and post responses to the similarities and differences between these two types of microscopy? (5 mins). Request students to source some Magic Sand from their lab tech (also available at most toy shops) and bring it to the next class. Link to Padlet made available for students to post their comments of similarities and differences between the two types of microscopes to. Resources
