Lesson 1: Movement
What We're Going to Learn and Why it Matters
Wow! There is nothing like seeing a master gymnast at work. Check out Simone Biles at the Rio olympic games. (Fast forward to 1:50 to see her in slow motion.)
You're moving all the time. We all are, but scientists really didn't understand what enabled the human body to move until the 1950s! By the end, you should be able to use an understanding of gross muscular anatomy and the ideas of opposing muscle groups to explain movements of the human body. |
Predict
(3:00 minutes)
Let's start with something simple like the flexion and extension of your elbow. How do you think that happens?

Introducing a Model of Muscular Action
You live in a time when information about all kinds of scientific topics is easy to come by. But imagine if you weren't. Imagine you live in a time before anyone knew much about the working of the human body. There is no internet. There are few books to go to. The books that are out there are as full of hearsay and superstition as they are of information.
Turn and Talk: How would you go about answering questions about how the human body moves.
Here's a model of muscular movement that we'll use in today's lesson. Let's look at it together.

Small Group Investigation
(40:00 minutes)
We're going to start with a look at the gross anatomy of the arm to help us answer this question. Gross anatomy is not necessarily disgusting. (Though I'm not ruling that out.) Gross, in this sense, means macroscopic--stuff that we can see without magnification. Use the images attached to Google classroom as your only source to apply our model of muscle action to an elbow that flexes and extends. Make a well-labeled poster that addresses all the aspects of our model. Attach a photo to the assignment on Google Classroom.

Whole Group Consensus Discussion

Individual Summary
(4:00 minutes)
Take a moment to post individually on Google classroom and reflect on your learning in this lesson. You may do this in several ways.
Take a moment to post individually on Google classroom and reflect on your learning in this lesson. You may do this in several ways.
- Summarize what you've learned about gross muscular action in three or four key ideas.
- Speak briefly about how this learning has changed your understanding of how we move.
- Reflect on how this knowledge might be important.
- List questions or confusions about this that still remain.
- Any combination of the above.
