★ Modeling Muscles ★
Our Modeling Muscles kit includes an acurate 1-foot tall human skeleton on a stand along with red modeling clay. The right elbow contains a movable hinge to demonstrate a joint as well as muscle attachment points.
Students can see the elbow muscle in action using a rubber band or model each muscle with never-dry red modeling clay to explore the size, shape, and connection points of each muscle.
Free web-based augmented reality (AR) enhancements introduce additional concepts by overlaying digital visualizations directly onto the physical models, including:
- The movement of other joints
- 3D muscle modeling guide
- Modeling the circulatory system
- Modeling the nervous system
Sometimes the most mundane obvervations are the most amazing. . . if we slow down enough to ponder them.
Every ShoeBox Education kit includes a recommended observation or simple phenomenon as a way to introduce the topic and encourage curiosity. See our recommended approach to using physical models in the classroom for more.
Think of the most careful, delicate thing you've done recently. Maybe it was threading a needle or holding a baby or handling fragile glassware. Now think of the most intense or strenous thing you've done recently. Maybe it was splaying a sport or doing a chore or running from a man-eating tiger. How did your body move with such precision? How did it also move with such strength? What controls that movement? How does your whole body coordinate movement?

1.) Sorting and Findinging Patterns
Sort the bones by color and discuss any similarities or differences observed between them. Sort them by species, using the printed Species Cards to help if needed, and discuss any similarities or differences observed between them.
Do you think the four species are related? In what way? What might be the cause(s) of their relationship?

2.) Studying Complete Skeletons (using Augmented Reality)
Assemble the arm bones of the four species and place them on the printed Species Cards. Open the AR Webpage on any mobile device with a camera and scan each Species Card to display the full skeleton.
Are there similarities in the leg bones, like there are in the arm bones? Are the skulls similar? Are there differneces as well? Why are some parts of the skeletons more similar and others less?

3.) Exploring Muscles (using Augmented Reality)
Assemble the arm bones of the four species and place them on the printed Species Cards. Open the AR Webpage on any mobile device with a camera and scan each Species Card to display the arm muscles of that species.
Are there similarities in the muscles, like there are in the bones? Are some muslces larger or smaller in different species? Why are some parts of the muscular system more similar and others less?

4.) Skeletons to Scale (using Augmented Reality)
The physical models do not accurately capture scale. Open the 3D Webpage on any mobile device to display all four species’ skeletons at the same scale.
How do the sizes of the four species compare? How might their size relate to how the species behaves or what it can do? Why are some species large and others small?

5.) Survival of the Fittest
Start by forgetting that these are bones from four real species, and instead picture them simply as an assortment of bones with a range of diverse traits. Combine one hand, forearm, and humerus of your choice to build an arm of an imaginary species.
What advantages might the arm you constructed give your species? What disadvantages might it have? What habitat or conditions might allow it to survive? What habitat or conditions might not let it survive?
