Objective: To observe the microbes and pathogens we have been learning about under the microscope

Lesson:

1. Bellwork:
   Pick THREE parts of the Microscope and describe their function.
   Escoge tres partes del microscopio y describir su función.
2. Students will look at different microbes/pathogens under the microscope and draw what they observe for each one (done on their own paper- no worksheet provided).
   Microbes looked at:
   

• Bacillus Bacteria (Can cause Tetanus, Tuberculosis, and Leprosy)
• Hookworm (Parasite- attaches to small intestine)
• Liver Fluke (Parasite that can live in your liver)
• Plasmodium (Parasite that causes Malaria)
• Mite (Parasite that can cause Scabies and Mange)
• Blood Infected with Tuberculosis (Bacterial infection, destroys lungs)
• Malaria
• Blood Infected with Influenza (Virus, can lead to death)
• Cross section of Tapeworm (Parasite- lives in intestines.  Can grow to feet long)
• Pinworm (Parasite, Lives in Anus)
• Ascaris Larvae (parasitic worm)
• Streptococcus (Bacteria that causes Strep Throat)
• Tick (Vector for Lyme disease)
• Bed Bug
• Head Louse (Causes Lice)

3. Follow up questions (answered on students own paper):
1.Is it possible that microbes exist that are smaller than those you observed?  Explain how you might try to collect evidence to prove or disprove your idea.

2.Develop three rules you will use the next time you do microscopy drawings

3.As a scientist you are asked to describe two of the microbes that you saw to someone who has never looked through a microscope.  Write a short paragraph describing the microbes you observed.

4.Imagine that you are a researcher studying microbes.  Would you choose to study a disease-causing microbe or one that does not cause disease?  Explain.
