The Chemistry students learned about three different types of ionizing radiation: Alpha, Beta and Gamma radiation. We saw the 3 different sources in action, too. We saw how they were able (or unable) to penetrate cardboard, glass or lead. We also saw how activity levels decrease when the distance from the radioactive source increases.
The AP Biology students began a review of material in preparation of the Evolution Exam, which will be given on Thursday, February 12th.
