Sea Urchin Fertilization Laboratory
Vic Vacquier developed a handout for university students on how to observe sea urchin fertilization in a university lab class setting. All that is needed are sea urchin gametes, a microscope, a few solutions and this handout. The handout works well for both 1 or 2 three hour labs. The student reads through the handout, makes the simple observations, and does the simple, direct experiments to gain insight into the fascinating process of sperm-egg interaction and egg activation.


Ocean Life Class for K-5
