In this activity, learners make models representing bones on Earth and bones that have been in space. They discover what happens to bones without proper exercise and nutrition.

In this activity about engineering, nutrition, and physical activity, learners design and build a healthy bone model of a space explorer which is strong enough to withstand increasing amounts of weigh

In this activity (page 32 of PDF), learners investigate the nutritional needs of healthy bones and muscles.

This is an activity (located on page 3 of the PDF) about the mixture of materials in bone and how they affect its strength.

This is an activity (on page 2 of the PDF under Bone Regrowth Activity) about the two main components of bone - collagen and minerals (like calcium) - and how they each contribute to its flexibility a

Just like birds, some dinosaurs had air-filled (pneumatic) bones, which made the dinosaurs' skeletons lighter.

In this activity, learners will use cereal to conduct an experiment and investigate how decreased bone density is related to increased risk of bone fracture.

This activity features two connected hands-on activities about dinosaur bones.
