Hope everyone had a great Thanksgiving break and that all our hunters practiced safety first. If you would like to post pictures of your vacation or you big buck, just make sure you have parent permission and that they are appropriate.

Thanks for working so hard to get all your work turned in prior to Thanksgiving break. I will have your class average upon return. We met our goal of 100% Work Turned In so our popcorn party is a go! Yeah…………

Homework assignments:

• How Small is Small? Microscope Vocabulary Test - Due: Dec 11th ---- Review on Podcast! Subscribe now at All you have to do is download and listen to review several times throughout the week and you should be able to ace the test.
  
• Cells and Things Word Search - Due: Dec. 14th
  
• Cross Section of Plant Cell - Due: Dec. 16th --- The sky is the limit on this assignment. Toss your idea out to me before starting. You must submit the image you will be reproducing. Images can come from the book or off the internet. Be sure to site the source whether book or website. You can make a module, decorate a cake, draw on poster board, etc. Just make sure you let me know what you plan to do prior to starting.

Thanks for all your hard work! I hope you all have a wonderful and safe weekend!

Microscope Scavenger Hunt

Microscope Scavenger Hunt

We have finally arrived to our How Small is Small? Module where will begin using the microscope. This scavenger hunt will allow us to learn a little about microscopes and its history.

A scavenger hunt is a way to look for answers using the internet instead of our textbook. You will need to print out the scavenger hunt blog and use the links provided to look up the answers. Write the answer on the printout to be turned in. You will have class time to work on the scavenger hunt but this assignment may require additional time in the computer lab or at home.

This scavenger hunt will count as two grades. The first assignment is the printed copy of the scavenger hunt with the answers inserted. This assignment is worth 100 points. The second assignment is to print off the completed microscope activity which is worth 100 points. As a bonus: you can leave a reply to the blog stating whether you liked this type of assignment as well as at least one thing you found interesting about the assignments. This post will allow you to add 10 points to your lowest test score.

This assignment is due on November 19th. Good luck and happy hunting.

1. What is the definition of a simple microscope? What are some examples?

2. Who was one of the first scientists to discover protozoa in water?

3. Using the same link as number 2, what four parts did his microscope consist of and what part did they play?

4. What did Anton Van Leeuwenhoek teach himself that played a huge part in his pioneering of the microscope?

5. In 1665, what did Hooke call the small units or compartments he saw in his specimen of cork?

6. Using the link below, we will take a look at the different magnifications of a moon rock. Select the sample Apollo 15 Moon Rock and then select each of the six powers of magnifications. Write a paragraph about your observations.

7. Drag the parts of the microscope by clicking the mouse and dragging the names to the correct location. You will receive two “lives” or tries and then you will have to start over. Once you have all the names in the correct place you will receive a “Well Done” notification. At that notification, select the print button or go to file and select print to print off the assignment. Print your name inside the Google box. Make sure the microscope shows under the “Well Done” notification. Below the Google box, write the names of the parts of the microscope and the use for each part. Failure to follow instruction will result in deduction of points. This printout is worth 100 points.

Answers to the Scavenger Hunt...

Answers to the Scavenger Hunt:

1. What is the definition of a simple microscope?
simple microscope - light microscope consisting of a single convex lens that is used to produce an enlarged image; "the magnifying glass was invented by Roger Bacon in 1250" A microscope having one lens or lens system, such as a magnifying glass or hand lens.

What are some examples?
Examples: magnifying glass, hand glass light microscope - microscope consisting of an optical instrument that magnifies the image of an object jeweler's loupe, loupe - small magnifying glass (usually set in an eyepiece) used by jewelers and horologists

2. Who was one of the first scientists to discover protozoa in water? Anton van Leeuwenhoek

3. What four parts did it consist of and what part did they play?
Leeuwenhoek's microscope consisted of:
A) a screw which was used to adjust the height of the object
B) a metal plate serving as a base
C) a skewer to home the object so it could be rotated
D) a lens to look through
4. What did Anton Van Leeuwenhoek teach himself that played a huge part in his pioneering of the microscope?

He taught himself new methods of grinding lenses so that he could get better magnification for grinding and polishing tiny lenses of great curvature which gave magnifications up to 270x diameters, the finest known at that time.

5. In 1665, what did Hooke call the small units or compartments he saw in his specimen of cork?

Cells
6. We will take a look at the different magnifications of a moon rock. Using the link below, select the sample Apollo 15 Moon Rock and then select each of the six powers of magnifications. Write a paragraph about your observations.
Open answer.

7. Drag the parts of the microscope by clicking the mouse and dragging the names to the correct location. You will receive two “lives” or tries and then you will have to start over. Once you have all the names in the correct place you will receive a “Well Done” notification. At that notification, select the print button or go to file and select print to print off the assignment.
