Learning Sequence

Show all resources
  1. Teachers welcome students and introduce themselves. Ensure that student microphones and cameras are operational. Encourage several of the students to introduce themselves to the class.
  2. Introduce the features of WebEx – how to raise a virtual hand, ask a questions, display emotions using the GUI. Encourage students who have already done an NVSES subject requested to give some advice to those new to the course. Students are introduced to the suite of NVSES Google applications. Resources
  3. Provide a quick review of the Nanotechnology unit as a whole, including an overview of the topics. Reference should be made to the assessment tasks and major project (which is introduced in lesson 4.1 and due in lesson 7.2) and the 2nd hand data assessment task to be performed in lesson 5.2.
  4. Discussion – How is microscopy beneficial? Why it can be helpful to visualise things that are too small to see with the naked eye? How can this change our understanding of the world? Information gathered on whether students have used microscopes in their studies. What makes one microscope better than another? Introduce an understanding the terms magnification and resolution. Resources
  5. Investigation – History of microscopes (focus on light microscopes), and the sizes of the objects that they are optimised for. Use Whipple website and the interactive microscope webpage. Resources

  7. Reflection – Now that you know about several different key types of light microscope, which types have you used or seen? Q - What do you think have been the biggest advances in microscopy? Q – How have microscopes changed what we know about microbes and the nature of matter? Q – How has this knowledge enabled us to do that we couldn’t do before?

Home Learning

  1. The following URL’s are made available from the NVSES website for students to explore. The first two sites from the NZ Learning Hub recap on the key points of lesson 1.1 and the remaining site provides a wealth of information for the students to explore the use of microscopes and their applications using examples of image grabs from iPads and specimen preparation for investigation.
