 Immune response reading  Antibodies activity  Puttin’ them in order  Exit ticket

 This is complicated.  Work in partners and make sure you are keeping each other on task and focused.  You’ll need to have out your notes.

1. A T Cell recognizes an antigen on an antigen-presenting phagocyte. 2. The T Cell reproduces rapidly. 3. Some T Cells signal B Cells to make antibodies to fight the pathogen. 4. Antibodies attach to the antigens, marking the pathogens for destruction.

 Each student will be handed a lid. On the lid will be a different pathogen.  You will see plastic containers spread throughout the room.  There is one container in the room with the same label as your lid.  At the signal, find the plastic container with the pathogen that has the same label as your lid and wait for me to tell you to stop. 

 If you still haven’t found the matching container, your model pathogen has spread.  If your pathogen has spread, write its name on the board.

 What does the lid and container represent and why?  How do antibodies identify pathogens?  Why do you think it is important for your body to identify pathogens?

 On the back of your article is our next task.  In your partner’s, you’ll read your scenario and figure out what’s happening with the immune system.  If you have questions, raise your hand and I’ll come by and help!
