ONLINE FIELD GUIDE FOR MICROSCOPE SAFARI
ONLINE MUSEUM OF MICROSCOPIC THINGS - USE THE CATERGORIES AT THE LEFT SIDE OF SITE
Online smallest site on the internet
April 4, 2006
Today you need to answer the following questions:
Save your answers on a word document - you can even paste pictures into them - and then publish it on your RWLO account.
1. How is a cell like a city? Give an example of three cell organelles (parts) and what thing in the city does the same job.
2. What are two differences between plant and animal cells
3. Find a microbiology current event and write a 5-8 sentence summary of it. Microbiology events are usually in the HEALTH section of the news sites. They can be about diseases, stem cell research, genetics, cloning etc. Include a link to the story with your summary.
To learn about how cells are like a city, try this interactive site that allows you to point to an organelle in the cell and see what it is like in the city.
To see pictures of cells and to see an interactive model of a plant and animal cell, try this site. Use the sidebar menu to find the plant and animal cells.

Today we are going to begin a station lab activity. There are six stations - 5 with lap tops and microscopes and one with the digital microscope. You are to take notes in your lab notebooks following the same format we have used for our other activities - sample name, magnification, drawing of what you see, description of what you see - or facts about it. You will do 3 stations today and 3 stations on Monday.
Station 1 Digital Microscope - work with your group to capture a digital micro image and then turn it into a piece of art.
Station 2 Forensic Science Check out the different carpet fibers under the microscope , then go to the following website to learn more about Forensic science.
Station 3 Unwelcome Guests Use the tape to collect samples of dust from the room and tape it onto a glass slide. What kinds of debris do you see under the microscope?
Use the following websites to find out more about the things that live with us!
Station 4 We are going to be looking at Algae next week in class. Read about algae and microplants, then go to the following websites to see more
Station 5 We studied archaeology in class. Read about how archaeologists use microscopes to learn more about ancient life! Then go to this website to see more.
Station 6 Nanotechnology Scientists are creating micro robots, medicines and machines. Read about them, then go to the following websites to see more.
Friday March 24
Today we are going to take a field trip to the museum of microscopy. It has been created by the National High Magnetic Field Laboratory (NHMFL) at The Florida State University . You are going to have a chance to see some early microscopes and then use the virtual microscope to view common items that you have seen before in a new way.
Each of the microscope pictures is a hyperlink - click on them to find the info. that you need :)
Station 1: Find out who invented the first compound microscope.
_______________________________ invented the first compound microscope.
It could magnify objects in a range from _________ times to _________ times by sliding the tube in or out.
**When writing out magnification, scientists use “x” to mean “times” so if something is magnified 40 times it’s normal size, it would be written 40x.
Hooke was a British scientist who came up with the idea that living things were made from “cells” after looking at a piece of cork (which comes from tree bark) under the microscope.
His microscope is different from the other ones we have looked at. How is it different? ________________________________________________________________He wrote a famous book on microscopy called ___________________________
This microscope is small but powerful. Van Leeuwenhoek made his lenses by using tiny droplets of __________________ that he ground down. They had a magnifiying range of ____________x to ____________x.
He was the first scientist to view protozoans, which he called “wee beasties”.
Station 2: A virtual microscope to try
Click on “scanning electron microscope”. Once it has loaded you can select what you want to view and adjust the magnification levels, focus and brightness.
Have fun looking at some common things in a new way.
Station 3: How does a microscope work
A basic microscope or magnifying glass (lens) produces an image of the object upon which the microscope or magnifying glass is focused. Simple magnifier lenses are bi-convex, which means that they are thicker at the center than at the edge.
Go to the following site:
Click on the blue lens and try sliding it up and down to increase or decrease magnification. Notice that the closer the lens is to the subject, the higher the magnification is and the bigger image is. Also notice that even though the actual giraffe is right side up, the image of the giraffe is upside down.
Go to the following site:
· Under the picture is a button for “manual” click on this.
· Now you can increase or decrease the magnification of this picture.
Note that as you increase the magnification, you can see more detail, but you see less of the big picture
Next, Go to:
This is the online simulator for our computer microscope. The directions are below.
Follow the written directions
Using the special art effects:
1. Take a snap shot of the image
2. Click on the green arrow in the bottom left of the control screen
3. Select the paint button
4. The buttons on the left give you the paint options, including paint, text, and rubber stamp. The color and texture choices are in the boxes at the right of the image.
5. You can also select the F/X button. This will allow you to change the way the whole image looks.
6. To get back to the microscope, click the picture of the microscope in the bottom right corner of the control screen (it is in an oval not the big picture )
Follow the instructions listed below to operate the microscope. A detailed explanation follows the list.
· Place your mouse cursor over the green button on the Choose A Sample menu and select a sample. It will slowly appear in the Live View screen. The samples in menu #3 are default and automatically download with the applet. You can select different samples from menus #1 and #2.
· Use the mouse to adjust the focus of the sample with the blue focus knob.
· Make sure the proper illumination source (top or bottom lamp) is turned on. If the wrong source is chosen, the sample will appear very dark.
· Rotate the green magnification ring to choose the 10x (default), 60x, or 200x objective. A higher magnification view of the sample will appear in the Live View screen.
· You can simulate capturing a digital image by pressing either the Snapshot button on the screen menu or by clicking the mouse on the uppermost green button on the microscope.
· During periods of inactivity, the tutorial launches a screen saver that bounces the image from the Live View screen around the small computer monitor. The actual QX3 microscope software takes control of the computer video drivers and deactivates any screen savers during operation.
· Click on the green reverse arrow in the lower left hand corner to go to the Main menu. The last image captured by the software will appear in the large window of the Main menu. From the Main menu, you can exit the software to the Windows desktop by clicking on the stop sign icon in the upper right hand corner or return to the Live View menu by clicking on the QX3 icon in the lower right hand corner.
· When you finish playing with the microscope, use the mouse to click the monitor button to the off position.
Thursday March 9 - Thursday March 16
We are going to be deciding how to educate the public about toxins that have accumulated in Lake Erie. They need to know what the toxins are, how they are effecting the food web starting at the microscopic level with bacteria, protozoans and algae and how they are effecting us. They also need to know how they can help limit these toxins personally and through laws created by the national and local agencies.
I will give you handouts that you can use as resources. I also have created a list of website resources http://www.rwlo.org/refdesk.aspx?folder=144560
You can choose to create a power point, write a story, write a song, write a play, create a series of cartoons, or maybe you have your own idea. You are each to do this individually. You must decide who your audience is going to be - elementary age children, middle school/high school, adults, everyone. It is due on March 16.
You will have computer lab time to work on it on March 13.
