Microscope Intro (Ecology Test Day)

Bellwork (8 minutes only) What makes this compound microscope different from the dissection microscopes we’ve used? Copy the labels onto your handout Organize 3 ring binder (all in order) & review for test

Before the test- Revisit the essential question for ecology How do the interactions of living things and the environment affect our world? _______(old answer)__________ ____________________________________________________________________________________ NEW & IMPROVED ANSWER: ____________________________________________________________________________________________________________________________________________

Ecology Unit Binder Check Notes Labs Assignments Tests -What is Life Notetaker -Energy Flow Notes -Trophic Levels & Rule of 10 Notes -Biome Poster Notes/Research Notes -Aquatic Macroinvertebrates & Water Quality -Population Notes Pull out the ecology Divider +2pts each assignment present Flip through notebook & score as Ms. D puts assignments on board Circle score at top (24 pts possible). Pass forward. -Cricket Mark & Recapture Lab -Aquatic Macroinvertebrates Lab -Jackrabbits & Coyotes Lab -Critter Outline -Overpopulation Article -What Is Life Quiz

Microscope Care & SAFETY Take only from appropriate cabinet Always carry with 2 hands (base & arm) ONLY use lens paper to clean Do NOT force knobs Keep away from table edge & keep objects clear of cords Store covered & w/ stage down aka “put it in park”

How to Focus Place slide on Microscope Use Stage Clips Click Nosepiece to the lowest (shortest) objective Look into Eyepiece Turn Coarse Adjustment (big knob) to focus; move slide if nessary Click to medium objective Use Coarse & Fine Adjustments (big & little knobs) to focus Give students a slide from the “common things” set, each student will practice focusing and changing objectives.

Using High Power 8. Click the nosepiece to the high power (longest) objective 9. Do NOT use the Coarse Focus Knob anymore 10. Use ONLY the Fine Focus Knob (little knob) to focus on high power Have students exchange slides so they can look at different things, walk them through using the high power objective to focus slides. Emphasize not using the coarse objective during this process, as it will crack the slides. What can you find on your slide?

After you finish the test, head to your NEW lab table and practice focusing on the slides!
