RAPS provided programs for pre- college education in Rochester and surrounding area. I designed the Saturday Morning Lecture series and mentoring pro- gram for children beginning in fifth grade, a teacher-for-a-day contest, and providing teacher-scientist ad- visory relationships. This program is still ongoing and is probably im- proved. My wife, a semi-retired school psychologist, and I have travelled with our congregation members to Cuba multiple times to bring sup- plies to the small but vibrant Jewish community there.We have been to multiple cities (not just Havana) and bring duffle bags full of medical sup- plies, diapers, pens and even soap! It is a very moving experience. Antioch taught me how to pack quickly (LOL), gave me a solid sci- ence training, an appreciation for diversity and passion for research. Professors like Ed Samuel and Stanley Garn inspired and chal- lenged me and allowed me to grow. Antioch taught me to care for others who are less fortunate. I am committed to Antioch’s re- birth as a viable residential college, was on the science advisory com- mittee and will continue to support Antioch. Maybe I can get an honor- ary bachelor’s degree! • Antibodies can only combine with two antigens since they have a “valence” of two, that is, two combining sites (see next item). Therefore, all students who are holding more than two balloons (under their arms, between their legs, etc.) are instructed to let go of them. • Students are reminded that this antibody combining region is represented by their hands, and so they must only hold onto the appropriate balloons with their hands. For example, students can be informed that a lobster might also represent an antibody molecule with the combining sites represented by the claws. • Students holding different colored balloons are then asked whether this is possible The teacher and/or audience should inform the students that an antibody combines with two antigens, but they are both identical (same color). An exchange of balloons can then occur at this point. • If the students have simply held onto only two balloons each at this time, they should be asked if any other kind of formation can occur. The teacher will then suggest that the individual antibodies might link up with a shared antigen. This is a slightly more complicated concept, but informs the students that an antigen may have repeating determinants and, therefore, two nearby antibodies can combine to crosslink a group of balloons (antigens). Then a group of students (for example, 3-4 students) might form a nice lattice, each holding one balloon, but connecting to another student holding the other side of that balloon. Thus, they form a human agglutination reaction!
