This blog hosts podcasts created by Mr. Jesse Craig at Arapahoe High School in Centennial, CO. The podcasts are designed to provide outside-of-class help to my 9th and 10th grade Biology students. The topics of each podcast as well as its levels are also listed as tags for the podcast to aid in searches. Rather than watching podcasts on this page, another option is to click the title to any podcast in order to download the podcast in mp4-video format, in order to watch on an iPod. You may also subscribe to this podcast in iTunes in order to sync to your iPod.
