Crash Course videos are a great resource that can be found on YouTube for free. Hank Green takes Biology and puts a comedic spin on it that the students enjoy.
I have created a guide that goes in order of points that Hank makes throughout the video. This is a great way to reinforce important topics that you have already covered during notes, and goes along with the standards that Quality Core ask you to teach your students. I personally use this so students are actively learning and paying attention during the video as well as allow them to staple it to their notebook for an interactive notebook page.
I will be making more Crash Course Biology video guides as I go through the year, so if you like what you see, stay tuned for more!
