Scavenger Hunt
Topic: Electron Microscopes
Lesson Objective: To show the value of electron microscopy in understanding cell biology. To understand electron microscopes, how they work, the different variety of scans and to relate this all to how structure and function work together on the cellular and sub-cellular level.
California Content Standard: Cell Biology 1e & 1g, Genetics 2a & 2b
Subject Matter and Grade Level: Cell Biology and Genetics for 9-12th graders
Web sites to help answer the questions:
Overview of each type of microscope - Electron Microscope Types
Scanning Electron Microscope Demonstration - http://www.mos.org/sln/SEM/sem.mov
SEM Images - Check These Out
Transmission EM explaination - Animation
TEM Image Gallery - TEM Pics
Reflection Electron and Scanning Transmission Electron Microscope Overview and Drawing - Electron Overview
Questions:
In electron microscopy, what can we see and how can seeing those things help us relate structure to function?
1. What are the visualization limits for each type of EM?
2. What is the advantage of scanning?
3. What is the advantage of transmission?
4. What is the advantage of combining scanning and transmission?
5. How did the discovery of EM influence research as we know it today?
6. What would you like to see under a EM and why?
7. Name a cellular structure that you viewed an EM image of and relate the structure you saw to its function?
8. In reference to mitochondria, how does cellular respiration take place within the membranes of its structure?
9. In reference to the Golgi Apparatus combined with the Endoplasmic Reticulum, are there any concepts that now 'make sense' after seeing and EM image? Why?
10. What are some ways you think EM could be used in the future that aren't being done right now?
