What Makes Our Bones Strong?
So is that what you meant by rubber legs? The activity has pairs subject a chicken bone to vinegar and observe what happens over a period of days. Individuals then write up a lab report and document their observations and findings.

What Makes Bones Strong?
Students explore the function of bone, muscle, and skin. Pasta and rubber bands are used to model how minerals and collagen contribute to bone strength. The effects of the reduction of these substances are explored in chicken bones.

Anatomy of Living Bone
Students analyze and examine the anatomy of bones and bone conditions. In this bone anatomy lesson, students analyze and examine the structural properties of bones. They explain the relationship between osteoblasts and osteoclasts and...

Bones, Bones, and More Bones
Students describe the functions of bones in the human body. They describe the make up of a bone. They engage in a series of wonderful hands-on activitiies that reinforce learning of bones and the skeletal system.

Skeletal System
Third graders describe and identify the parts of the skeleton and how they support the body. They observe two chicken bones that have been soaked in vinegar for 5 - 7 days. They observe the bone's appearance after it has been removed...

Skeletal System
Learners discuss the need for humans to have a skeletal system and what would happen if we did not have bones. In this skeletal system lesson, students label each bone in the human skeletal system as a group, and then examine two...

Skeletal System
Seventh graders explore the functions of the skeletal system. They collaborate in small groups to determine the function of the skeletal system, the types of joints and movement, bone strength and growth, and bone injuries including...

Getting the Minerals Out
Students explore the tissues of the bone. They discuss bone composition and physiology. Students perform experiments to compare and contrast the decalcifying properties of several liquids.

Marine Habitats of Galveston Island
Four lessons introduce elementary ecologists to salt marsh and sandy beach habitats. In the first lesson plan, they place shells and other materials in vinegar to determine if they contain calcium carbonate. In the second lesson plan,...

Healthy Teeth: Hands-On Science Activities
Learners work in small groups to perform hands-on science activities that demonstrate the effect of certain foods on our teeth. They perform three different experiment with different foods in order to see the results.
