To take one step, the body uses about 200 muscles. In the video, learners see the difference between the three types of muscles found in the human body—skeletal/striated, smooth, and cardiac. The instructor then explains, in detail, how myosin and actin work to contract a skeletal muscle in the presence of ATP and calcium, or the sliding filament theory.
- Place learners in pairs and pause video, asking pre-scripted questions about the filament theory and allow time for discussion
- This is the sixth video six in a series of 21
- Assumes learners have some understanding of ATP and its role in the body
- Video teaches concepts important in AP Biology and other higher level biology classes
- Uses high-quality images and diagrams
- Video is short, allowing time for follow-up activity to support the concepts taught
- Includes closed captioning for those learners who struggle with English or are hearing impaired
