The zero gravity environment onboard the International Space Station enables astronauts and researchers to better study health issues that impact people on Earth.
Alignment to NC Essential Standards
- 8.PCH.1.2 — Explain behavioral and environmental factors that contribute to major chronic diseases and the methods for reducing problems associated with common conditions.
At the end of the lesson students will:
- Describe the ways in which a zero gravity environment can impact bone density.
- Discuss the ways in which examining zero gravity effects on the human body can advance medical therapies for some chronic diseases.

- "How will the Mars Mission Physically Affect the Astronauts?" — Mars One.com
Test students’ understanding of the NC Science Now video Science Above North Carolina with the following questions:
- What is zero gravity?
- Describe the relationship between gravity and vital organs. Why is gravity necessary to keep these organs healthy and functioning?
- How much faster does bone loss occur in space than it does on Earth?
- Why might it be important to have pharmaceutical therapies available for astronauts traveling to Mars?
