...good sites where [I] can find videos or even a good podcast for cellular biology?
Cellular Biology recommendations were first made by Michelle Eckstein, Shaun Fletcher and Britt Gow. Here is my response to the excellent request:
Good recommendations from all. I have used the Cells Alive website which is excellent, as are the others.
I would like to recommend a science education portal BioInteractive. Their motto is, "Teach Ahead of the Textbook", and BioInteractive is part of a worldwide effort by research scientists to help more people learn about science. Their focus at BioInteractive is providing material and information for science educators and their students.
Research labs and universities provide excellent virtual labs, still images, "Holdiay Lectures" on a science topic, videos, podcasts and so much more. I have used various BioInteractive materials with 6th - 12th grade students. Many of the materials could be used with younger students.
You can sign up for the HHMI Bulletin. The May Issue
would be very helpful to teachers. Also, you can receive their newsletter and get science research and news updates that can be used as current events for science or professional development information.
