    • Smart phone or iPad
    • Transfer pipette
    • Spatula
    • Sample cups
    • DI Water
    • Alcohol wipes
    • Diffuser
    • Natural samples (students will collect these)

    Procedures

    1. You will collect specimens in the sample cups. Look for:
      • -Soil
      • -Water
      • -Algae
      • -Lichen
      • -Other?
    2. If the sample is dry you will need to add a small amount of water to the sample cup.
    3. Reconvene with the class to view and image your samples.
      1. Turn on the scope.
      2. Place a very small amount of liquid on the lens.
      3. Take images/video.
      4. While observing and after imaging,attempt to ID the microbes that you see. Imaging tip: If you want a more magnified image or video, increase the magnification (zoom in) onyour phone prior to taking the image or video.
    4. Use the Protist handout to try and ID any Protists you may find. You may only be able to ID the Domain/Kingdom, but you may be able to ID it further.
    5. Fill out the following chart.
    6. Clean up the scope and return all parts neatly together. Use the wipes to GENTLY clean the lens.
    7. Post image/video on CANVAS. Send images to partners without iPhones.
