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
“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.

Hi Stephen, I thought you might also be interested in our Inquiry-2-Insight program. The Inquiry-to-Insight (I2I) project ( http://i2i.stanford.edu ) is a collaboration between Stanford University in California and the University of Gothenburg in Sweden and is designed to promote environmental science education through information and communications technology use in the high school classroom. Students in the I2I program collaborate across international borders via social networking and other Internet collaboration technologies to investigate and envision solutions to global environmental problems. Two biology or environmental science classes from two different countries are partnered and share inquiry-based investigations to explore environmental concerns. By sharing perspectives on how their respective communities view these environmental challenges, students transcend their parochial points-of-view, motivating them to envision solutions to the vast environmental problems and challenges of the 21st century. Please see the website at i2i.stanford.edu and let me know if you might want your class(es) to participate.
Cheers,
Pam Miller
