This is a good time to direct your attention to my favorite professional organization: The Association for Biology Laboratory Education, or ABLE. I raved about ABLE in a previous post, and I won’t repeat my praise here. I just wanted … Continue reading
Every now and then I write a blog post about lab activities that worked in my nonmajors biology class. For example, I have written about reptilobirds (an activity combining meiosis and inheritance), staining banana cells to illustrate digestion in plants, … Continue reading
