This article is a great extension to a body systems unit - health issues affecting the body systems. When students apply their understanding, the knowledge becomes deeper and more meaningful. The article is about Osteoporosis, which affects the Skeletal System. The article is written in friendly and engaging language and includes a diagram. The article is a little more than a page long and includes standards-aligned comprehension and analyses questions. I use the article in my body systems unit (7th-grade essential standards). The article can be used for literacy groups, individual DEAR or homework reinforcement.
