Journal:
Explain how to focus a microscope. Discuss which objective lenses should be focused first and last as well as which adjustment knobs to use with each objective lens.
I handed out new late passes and hall passes today so if you missed class, come see me to get them. We finished the Using a Microscope lab and turned it in today. For lab makeup, talk to me about coming after school to finish. We also made the onion slide for a new lab we'll finish on Monday: Cheek and Onion Cell lab.
HW: bring a specimen (living or once-living) to class by next Tuesday 2/2 to view under the microscope
