- Focus:
A number of changes occur in our bones as we grow and develop. As we age, some of these changes can compromise our independence and abilities late in life. Some of the most devastating complications are due to loss of bone mass in the disease osteoporosis.

Introduction
Lesson 5, "A Look at Osteoporosis" builds on the previous four lessons by giving students an opportunity to explore risk factors and health habits related to bone mass across the life span. In the first activity, students create a flipbook that demonstrates bone resorption. The second activity graphs bone mass against age. Students use coordinates of age (x) and bone mass (y) to plot bone mass from childhood to old age. The third activity is a board game called "Os Costs ® ." As players move through life, they have choices related to their bone health. These choices are reflected in their diet (e.g., calcium-rich foods ) and activities (e.g., weight bearing exercises ). For each of their choices, players accumulate or lose bone mass (" Osteo-coins "). Occasionally fate plays a hand in whether or not bone mass is increased or decreased (e.g., men have higher bone mass than women and get extra "Osteo-coins" for this ). The types of choices and values change at different stages in life. Players track their choices and fates and record the values of their moves onto the "OsCosts ® Game Log." The object of the game is to reach old age with enough bone mass (" Osteo-coins ") to be above the fracture threshold. Players with bone mass above the fracture threshold are less likely to suffer fractures and other conditions associated with osteoporosis. This activity has students working together and actively discussing their current habits, health habits that effect their bones and future lives.

Objectives
Students will be able to:
- Sequence illustrations depicting loss of connectivity, then compile the scenes into a "flipbook" to "animate" bone loss.
- Utilize a graph to plot bone mass in terms of "grams of calcium" and "age" to determine their relationship to the "fracture threshold."
- Construct an understanding of basic bone biology and osteoporosis by participating in the Os Costs ® Game.
