Image 3.1a
After reading p.102 and studying Figure 3.4, go to Slimber.com and draw your own version of a phagocyte “eating” a pathogen.

After reading p.105 and studying Figure 3.8, go to Slimber.com and draw and label a B cell and its antibodies.
**Section 3.2 Factors Affecting the Immune System**

====//A vaccination is the process of receiving a vaccine. A vaccine is a special version of an antigen that gives you immunity against a disease. You can think of a vaccine as a weakened form of a disease. Vaccines are usually given by needle or in liquid form. They work by stimulating your immune system to create antibodies against the disease.*//====

====(Just to make things a bit clearer, the immune system attacks antigens, pathogens and allergens to protect your health.) Go to Slimber.com and follow the instructions below to create two images on **one page**.====


 * ====Draw a "before" image where there are few antibodies.====


 * ====Draw an "after" image where there are more antibodies. In addition, draw the thing that caused the body to produce more antibodies. If you don't remember what that thing is, reread the passage above.====

====After reading p.114, go to Slimber.com and draw a simple version of Figure 3.15. It’s not necessary to draw details like the tiny beige and green shapes. Label what you think are the virus, the outer envelope and the proteins.====
