A first look at the AST Pond

Today’s Key Question: How can microscopes help us learn more about life on Earth?

By the end of class, I should be able to:

  • safely handle a microscope
  • prepare and use a wet mount
  • determine the level of magnification that I am using when looking into a microscope.

Class Opening:
Please place your bags at your seat. You now have 20 minutes to complete the design of your wall blog. If it is your scheduled day to find class data, please do this before working on your wall blog.

Microscope Basics

  • Parts of a microscope


  • Safe handling & Care

Let’s go get water from the AST pond!

  • Preparing a wet mount. I need a cover slip, a slide, a pipet and a sample of the pond water.

  • With a partner, begin using a hand lens and a microscope to observe. Please pay attention to the level of magnification being used. Observe, draw, question.


Possible life forms


For Friday's class
1. Finish microscope lab questions
2. From today's drawings, chose your favorite and make it a "final draft" for posting on your blog. Please include the date, level of magnification, the awesome drawing and a caption that describes the drawing.
