Brittle Bones: A Density Problem

$18.95 – $154.95

Three generations of a family learn how osteoporosis (low bone density) results in bones that are brittle and easily broken.

Design and assemble models of bones to represent bone densities at different ages.
Determine the density of each of the bone models.
Use the models along with graphs and data from research studies to correlate bone density with osteoporosis and bone fracture risk.

MS-PS1-1. Develop models to describe the atomic composition of simple molecules and extended structures.

Science & Engineering Practices
Developing and Using Models - Develop and use a model to describe phenomena.
Disciplinary Core Ideas
PS1.A: Structure and Properties of Matter - Chemical composition, temperature, and pressure affect such arrangements and motions of atoms, as well as the ways in which they interact. Under a given set of conditions, the state and some properties (e.g., density, elasticity, viscosity) are the same for different bulk quantities of a substance
Crosscutting Concepts
Structure and Function - Complex and microscopic structures and systems can be visualized, modeled, and used to describe how their function depends on the shapes, composition, and relationships among its parts, therefore complex natural structures/systems can be analyzed to determine how they function.
