Grade 8-Cells Intro

Although scientists have studied living things for centuries, it was not  until the late 1600s, and the invention of the microscope, that humans  were able to see cells, the building blocks of all living things.
a) Who claimed to have invented the microscope? 
b) When did the microscope actually gain popularity and was first regularly used? 
c) Who was credited with the later development? 
-->There are two separate dates and centuries that I am looking for.

Today scientist still study cells, and are still attempting to learn more about  life through the function of cells and their parts.

You were given a number. Your topic is based on your number.

1. Cancer 2.  Alzheimer's Disease 3. Malaria 4. Cystic Fibrosis 5. Sickle­ Cell Disease 6. Diabetes

Individually, use the next five minutes to perform an internet search  for your assigned topic.  Scan the information, looking for references  to cells.  You will be discussing your information. Jot a few facts down.

Find your group and discuss your findings. You will be creating one power point slide with the information about your topic.  Do this in a group. Please send the slide to me. I will be creating a power point of these findings.

Grade 7-Chain of Events

This is a Murre (mer). It is a white-breasted North American Auk or seabird. In the summer, it breeds off the rocky coasts of Alaska, Canada, Greenland, Scandinavia, and Russia. But in winter, the thick-billed murre is at sea, off the edge of open ice southward towards Nova Scotia and northern British Columbia.

YOUR TASK
People have often thought about the impact of one tiny event on an entire chain of  events.  Sometimes the results can be surprising.
1. With a partner, read the following poem and discuss what it means.  If you  have any difficulty, invite other pairs of students to share their ideas. For want of a nail, the shoe was lost; 
For want of a shoe, the horse was lost; 
For want of a horse, the rider was lost; 
For want of the rider, the battle was lost; 
For want of the battle, the kingdom was lost. 
And all from the want of a horseshoe nail. 
2. Relate the ideas in the poem to the world around you and to the ways that living and non­living things depend on each other.
 3. Think about your "wants" — the basic things that you, as a living creature,  must have in order to live.  List the "wants" that are essential for your survival.
4. Make up your own chain of events starting with one small event.  Include at  least five events in your chain.  For example, you could start with the  following event: there was no milk left when you went to have breakfast this morning, so… Your homework for today is to complete your "For Want Of..." poem You can do this with a partner.
