Virtual Urchin – Tutorials from Stanford

Here are some flash tutorials from the team at Hopkins Marine Station, Stanford. They make good use of the properties of the sea urchin’s gametes for studies and learning experiences:

Fertilisation and Development Lab

Fertilisation and Development

“Gametes of sea urchins yield exceptional experiences in the classroom; teachers and students alike are riveted by being able to observe fertilization, cell division and embryonic development. The gametes are easy to use, the developmental stages are readily seen with the microscope and the rapidity of fertilization and early cell divisions allows the student to ask questions and obtain answers within the bounds of a normal classroom schedule. The utility of urchins for inquiry-based science is unrivaled.”

Head on over there to have a go at some of their labs, including a neat microscope tutorial, practice with microscope measurements, fertilisation and development and a ocean acidification investigation.
