Blood Typing

Video on Blood Types

Blood Reading - Reading on Blood and Lymph p. 94-96 Blood Types

Blood Types are determined by one factor:
The antigens found on the red blood cell (A, B, and Rh).  These antigens determine the type (A, B, AB, or if not present at all O) and whether it is positive or negative (Rh factor).

Whether you can receive or donate blood safely brings in a third factor of the antibodies found in the plasma.  

If antigens and antibodies of the same type come into contact clotting can occur.

Example Blood Type Card
You will create your own set of Blood Type Cards (8 total)
Side 1 (Front)  - Picture of the red blood cell on it with the correct antigens, antibodies, and Rh Factor.
Side 2 (Back) - List what blood types it can receive safely and which it can not.

Blood Drive

We will also begin work on our Blood Drive projects in preparation for the HMS annual Blood Drive on December 15th

You can start to make a list of 10 people you will ask to donate blood in hopes that one will say "yes".  Think of neighbors, family, friends who live close to Yarmouth.  

Here is an example of a sample donor letter to send to your selected 10 donors.

Prep for Maine Biotech Day - Wed, Nov 9th

Click here to access the Google Document to Guide your Work Today

Link to Biotechnology Current Event Document

Bioscience of Maine (BAM) is hosting Maine Biotech Day
Wednesday, November 9th here at HMS.
We will welcome Dr. Norman Moore from Alere to our 7th grade Science Classes.

“We are establishing Maine BioScience Day to create lasting interaction and cooperation between
industry, researchers, teachers, and students. The Bioscience Association of Maine and our member
companies are one helping hand to nurture our students and create awareness about the incredible
opportunities for future careers that are waiting for them as soon as they graduate high school or
college. The “jobs of tomorrow” are already here and waiting for them, and we hope to help show our
students how the science they learn in school prepares them for a very rewarding career, whether it is
as a scientist, engineer, accountant, software programmer, or graphic designer” said Bryan Bozsik, President of BAM’s Board of Directors.

Steps to use a compound microscope:
(when viewing and sketching at low power)

1. Plug it into the outlet, already placed between table
2. Make sure stage is down, on x40 (scanning)
3. Choose slide/ specimen
4. Turn on microscope, center slide over light
5. Adjust diaphragm if needed
6. View specimen, slowly turn course knob to focus
7. When focused, switch to low power
8. ONLY use fine adjustment, if problem finding specimen or focusing go back to scanning.
9. Once in focus, sketch on provided sheet.
10. When done switch to scanning, lower stage, take out slide.
11. Turn off, unplug, coil up and put away.

    Systems Worksheet...A _________ is a system

    Today we talked about how systems are made up of subsystems with outputs, inputs and boundaries.

    Here is the example of the one we completed in class on the hot pot/water heater.  The students have the challenge to come up with their own system they are familiar with.
