Symphony of Science – Quantum World
This Symphony of Science song is one of my favourites, which ties loosely to our new Grade 9 unit on Atoms.
Related to it is an update to the Powers of Ten video, from the IMAX Cosmic Voyage movie, narrated by Morgan Freeman. the start brings us in powers of ten, out into the universe. From 6:03, we start moving in – to cells, molecules and atoms.
Jump straight to the small bits here (6:03). Biology class will use it too, as we look into measurement and microscopy.
This is why we love Science.
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.
