Blood typing has always been and important biology exercise introducing a variety of key areas including immunology. Mainly genetics, blood banking, and forensics. Concern over Aids along with a general trend away from invasive" laboratory work has, for many schools, resulted in the elimination of this vital exercise. The ABO Blood Simutype Kit solves all of these problems. Using artificial bloods and sera that simulate actual blood typing, students follow exactly the procedure that would be used to type a blood specimen and obtain results that closely approximate real blood typing. Each student determines the type of one blood sample, A,B,O, and AB types are all included. From their results, students use genetic consideration to settle paternity questions. They also determine possible blood doners for each blood type.

The Solar System as seen from earth. This model shows the five planets and moon as Ptolemy described them in his famous book, "The Almagest". It describes accurately all the naked eye phenomena of our Solar System. The fact that most of the motions described by this geocentric system are incorrect cannot detract from the fact that to the unaided human eye all these incorrectly described motions appear correct. The use of the Ptolemaic model together with the Copernican model improves student understanding of the motions of the heavenly bodies. 14" high x 20" long. With fully-illustrated instruction book.
