7th graders recently used mice in their experiments in Biology Workshop—Animal and Medical Science. First, they learned the proper handling and restraint of mice. Then they carried out a maze test: the Morris water maze test, to test spatial memory and long-term memory. On June 1st, they learned the techniques of intravenous tail injections. First, the mouse was placed inside a restraint device. Then they identified the tail vein and gently inserted a needle into it. Those who did it successfully were very excited. They are very eager to learn the next technique—mice surgery!
