You move your body so much in the course of your daily life, but how often to you really stop to think, “How does this whole apparatus work?” We Wonder Grounders decided to take a closer look our own human bodies in motion in order to understand how our muscles do their work.
Activity 1: We began the session by flexing our muscles, bending our knees, and doing chair sits against a wall. As we went through these movements, we discussed how it felt, and closely examined the illustrations from David Macaulay’s The Way We Work to better understand what was happening under our skin.
Our stalwart Wonder Ground mascot Boneita Phalanges lent a hand–actually a whole arm–to give us a close-up, naked view of how the humerus, ulna and radius fit together.
Activity 2: Next, I challenged the Wonder Grounders to make a model of the human arm using common craft items.
Then I asked them three questions to help develop their designs:
- What will you use to represent your arm’s bones?
- How many bones will you include in your model?
- How will you attach the bones of your model to each other?
Then they got to work. Here are just a few of the models they made:
