PTT:
1) Turn to p. 108 in your science notebook
2) Tape a new Table of Contents to this page - label the unit title as Cell Biology
3) Write "Cell Biology" in the center of p. 109 - this will be our cover page (homework is to decorate this page)
4) Turn to p. 110 and title it "Parts of a Microscope"
5) Record the goal question: How do I use a microscope?
6) Get a copy of the microscope diagram (Compound Microscope Part A) and tape it to p. 110
Task 1: 1) We've learned about lenses and how our eye uses one, but what else can they be used for? Check out this video to see some of the amazing images that were captured with a microscope (impossible without its convex/converging lenses). Don't forget to read the background from part A on the worksheet!
2) Now that you've seen some of what a microscope can show you, you will complete the notes in your notebook.
Go to Google Images and search for "parts of a microscope" or "parts of a compound microscope." Scan through the images to find one that looks most like the microscope shown in part B. Using the results you find (you may need to use more than one image!), label the important parts of a microscope.
3) Go on to task 2 when done.
If you finish this, work on drawing and decorating the unit cover page on p. 109
Week 27, Days 2-3
PTT:
Take 5 minutes to finish up yesterdays activity on the parts of the microscope and function of those parts. If you already finished then take the time to study these as if you were preparing for a quiz.
Task 1:
Here is the rubric/checklist for the "Microscope Practical Test".
Download this and save it to your desktop. Carefully read over the details of the practical test. You will have to compete this practical test for a skills grade by the end of the week.
Task 2:
Today you will have the oppertunity to look at different things under the microscope. You will start with the letter 'F' then move onto an onion cell then pond water. Along the way you will be making DETAILED drawings of what you see.
1) Take a copy of the Lab: Microscope Observations worksheet. Read over the background information.
2) Complete Parts 1 and 2 of the Microscope Observations Lab. Carefully answer the questions.
Task 3:
Follow the instructions on how to prepare a wet mount slide (Video below). Prepare your own wet mount slide using the skin of an onion. Draw what you see on your lab paper.
Task 4:
Watch the below on 'Hidden life of Pond Water. Now it's your turn to look at pond water and draw what you see. Are you seeing any of the creatures featured in the video? Draw what you see on your lab paper.
Video Description by creatorDaniel Stoupin
"We don't need to dive into the deep ocean to find the most unusual lifeforms. This short clip is a journey into a bizarre world of microscopic inhabitants of pond water.
You will see water fleas, bryozoans, water mites, mayfly nymphs, ostracods, and, of course, hydras. They jump, crawl, and float in a completely alien environment filled with mesmerizing algae and bushes of ciliates on stalks.
This video uses image that I made through a biological microscope and macro lenses. I believe that macro work added more depth and allows seeing whole animals in a more natural environment. The average size of the animals filmed was less than 1 mm." Visit my website for more images:microworldsphotography.com
Closure: Self-Assess - do you feel like you understand how a microscope works and how people observe cells under them?
Week 27, Day 1
Table of Contents
1) Turn to p. 108 in your science notebook
2) Tape a new Table of Contents to this page - label the unit title as Cell Biology

3) Go on to task 2 when done.
Task 2:
1) Now that you know the PARTS of a microscope, you need to know how they work! Tape the Part C paper onto p. 111 in your notebook.
2) Copy the names of each numbered part in order onto part C. The numbers in the chart/table should match the numbers on your diagram.
3) Then use the following one of the following links to record the function of each part
http://www.microscope-microscope.org/basic/microscope-parts.htm
http://www.microscopemaster.com/parts-of-a-compound-microscope.html
http://www.tutorvista.com/biology/microscope-parts-and-functions#
4) When done part C, read over the rules for using a microscope (part D). Highlight the most important rules.
Task 3:
1) Go to this site to check over the parts again. It doesn't look EXACTLY like our microscope worksheet, but the parts are all the same (just some in different spots).
2) Go through the quizzes and test your knowledge. No peeking at your notes!

Use the following steps to guide you through the application:
Alternatively, do me a favor and test this one out. Let me know what you think:
