Overall, I think the building process went well for my group. At first, I found it kind of hard to choose a structure to build, because the Immune System had so many diffenrent structures. But then we made a plan to make several different models of Different Lines of Defense, Antibody Antigen Reaction, Vaccinations and a Display of Different Organs and Structures of the Immune System. For the Lines of Defense, we made two simple models, one being how the skin acts like a sheild to keep pathogens out and what happens when you get a cut. We used scissors, beige colored paper, and a clay pathogen for this model. The other model we made showing lines of defense in the Immune System was one that showed how mucus in the nose traps pathogens that may come in your nose while inhaling. We used Elmer’s glue in green food coloring, clay pathogens, and an enlarged nose made from cardboard. To show an Antigen Antibody Reaction, we made a very simple model out of cardboard, magnets and tape. We cut out a carboard Antigen and Antibody that fit inside one another, and we taped magnets to them to make them bind together. To show vaccinations, we used beige paper, a syringe with green water and yellow clay and a cup with cotton balls in it. The paper represented the skin, and the green water and clay showed anitgens, and the cotton balls were white blood cells. When the ‘antigens’ were put into the cup, the cotton balls absorbed it, or ate it. But the clay shows that they remember how to make the antibodies for that specific antigen. We only decided to make a display later into the unit. We made a cardboard person, then we glued clay organs and structures onto it. We made structures and organs such as Tonsils and Adenoids, Lymph Nodes, Lymphatic Vessels, Thymus, Spleen, Appendix and Bone Marrow. Then we made labels with definitions on the back. Overall, I think my groups models are good,

Above are pictures of some of the models my group has made. I think we are doing pretty well. At first, we didn’t know what we were doing, but then we made a proper design and we were able to focus much better. We are planning to bring all four of our models into the BBT and on Thursday I am planning to come to introduce it.
