If you really want to learn the ins and outs of the connections between cell cycle and cancer, this article is fantastic for that. I use it for Honors classes who are learning the ideas of p53 and telemore shortening. Excellent resource for learning more detail.
I like this article because it makes the connection between the cell cycle and cancer and explains why this topic is important in emerging Biology. It also has links to other areas of the cell cycle if you are interested in learning more.
I like Bozeman videos in general because they really get into the details of the different topics. While this video is detailed, it really helps students grasp the concept of cell division really well which is why I give it to upper level Biology students to watch.
I use this lab with some of my classes to allow them to physically see that cells in fact spend 90% of their time in interphase. By counting the cells in the various stages, students can see it in person which helps them understand that important fact of the cell cycle.
I have used this in the past with students who were absent on the day of the traditional onion lab as it achieves the same ultimate results as the hands on labs. It can be used for classes where the materials are not available.
My students have said that the videos and subsequent handouts have really helped them understand some of the harder concepts better. I use these regularly and the videos are entertaining and informative and the handouts help the students focus in on the important concepts you want them to learn.
The Ameoba sister's videos are great for regular level Biology classes (or middle school level classes) as they describe the information in a way that students can really understand. I personally use their videos as review after I have taught a major concept that I feel the students need more information on. They also each come with video sheets that the students can fill in after they have watched the video.
