  1. Monday: Do Now • 2nd, 4th, 6th, 7th Hour • Copy the content and language objective • Answer the questions in complete sentences • When using a microscope, which knob do you use to get your slide “roughly” in focus? • What knob do you use to get your slide “finely” focused? • What is the total magnification if the eyepiece is 10X and the objective lens is 10X.

  2. Monday: Do now • 1st and 3rd hour • Put the proper heading on your lab paper. • Title your lab: Microscope Lab (L001) • Copy the content and language objectives at the top (in the “background” section) • Question: What does ______________________ look like under a microscope? • Hypothesis: I think it looks like ____________, because __________________ • Constants: Time, temperature, light • Materials: Microscopes, slides, cover slips, water 2nd, 4th, 6th, 7th

  3. Tuesday: Do Now • 1st and 3rd Hour • Copy the content and language objective • Answer the questions in complete sentences • When using a microscope, which knob do you use to get your slide “roughly” in focus? • What are two reasons we do not run in the lab? • What is the total magnification if the eyepiece is 10X and the objective lens is 40X?

  4. Tuesday: Do now • 2nd, 4th, 6th, 7th • Put the proper heading on your lab paper. • Title: Microscope Lab (L001) • Copy the content and language objectives at the top (in the “background” section) • Question: What does onion look like under a microscope? • Hypothesis: I think it looks like little holes and layers, because onions have layers, and you might be able to see layers. • Constants: Time, temperature, light • Materials: Microscopes, slides, cover slips, water

  5. Procedure: 1. Get a piece of onion. 2. Make a slide from your onion. 3. Focus your microscope, and make drawings under one magnification. • Data: 1 drawing • Conclusion: what did we learn?

  6. Drawing In Lab – Mini Lesson • Look, Draw, Dark Lines, Erase, Detail, Color • Practice on the back of your microscope notes – Each drawing needs magnification and a name below it.

  7. How to label drawings

  8. Leaf Drawing

  9. Euglena 400X

  10. Lab Partners

  11. Do Now: -copy the language and content objectives -answer the following in complete sentences: 1. write a hypothesis for the following question: what does mold look like under a microscope? (hint: i think _______ because ____________) 2. which knob do you use to get the microscope finely focused?when you finish, work on your study guide (s002)

  12. Cue words: helps link information in your head.Summary: Makes it into the smallest, most important piece of information

  13. How to put a heading on your papers? Your Number Your First and Last Name Due Date (31 Aug 2011) Hour Switzer

  14. How to put a heading on your papers?CBM Name: C002 (Microscope CBM) #523 Olive Skool 31 Aug 2011 5th Hour Switzer

  15. Test Tips: • Read the question, think of an answer before selecting a choice. • Read all answers carefully • Eliminate answers you KNOW are wrong • Go with your first “gut feeling” • Skip a question if you’re stuck, and return to it later • Double check your answers when you’re finished • Mark an answer for every question • If you have no idea, then choose the longest answer, or letter C

  16. Do Now: • Copy the content and language objectives • Answer in complete sentences: • Write a hypothesis for the following questions: Which has bigger cells, a human or an onion? • What do you know that is one foot long? One centimeter? When you finish, read the objectives on your “What is Life Science” packet. *Reminder: Progress Reports due today.

  17. Opening • Measure the width of your desk. How many hands does it take?

  18. Measurement • Why should the U.S. change to the metric system? Or not?

  19. Measurement The Mars Climate Orbiter (MCO) In one of the all time great engineering mistakes, NASA’s partner, Lockheed Martin, used English Standard units, not the metric units used by NASA. The probe eventually hit the Martian atmosphere at the wrong angle and burned up.

  20. Friday Do Now: • Copy the content and language objectives • Write your answers in complete sentences • What measuring system do scientists use when they communicate with each other? • When scientists want to talk about a certain species, how many names do they use? • What is the scientific name for humans? When you finish, get out your Cornell Notes.

  21. The metric system is based on 10!

  23. Metric Measurement: • Almost all science uses the Metric System. a. This system is based on multiples of 10.

  24. Metric Measurement: • Almost all science uses the Metric System. a. This system is based on multiples of 10. II. Length is measured in meters, decimeters, centimeters, and millimeters. a. One mm ≅ thickness of your fingernail b. One cm ≅ width of your pinky finger c. One dm ≅ width of your palm d. One m ≅ height of a doorknob III. Mass is measured in grams, decigrams, milligrams, etc. a. One gram ≅ one paper clip b. One milligram ≅ 1/1000 of a paperclip
