Our World: Where Do Crops Grow?
Have you ever wondered where food comes from? Learn how Dr. Catherine Nakalembe uses NASA satellite data to show the health and location of crops around Our World. Maps created from these data help people become more food secure. You can help, too. Using the GLOBE Observer App, you can help scientists validate satellite data by describing land covering through the Adopt a Pixel program.
Discussion and Writing Prompts
1. Plants need many things to survive whether on Earth or in space. Why is it important to think of a plant-growing system as a group of connected parts instead of focusing on just one part? What might happen if one part of the system stopped working and how would that affect the entire system?
2. Imagine you are part of a team preparing for a long mission to Mars. Why do you think growing plants on the spacecraft or on Mars is important for the astronauts' health and success? Write a journal entry from the perspective of an astronaut describing how caring for plants helps you live and work in space, including both practical and emotional benefits.
3. Growing plants in space is more challenging than growing them on Earth. What do you think is the biggest challenge astronauts face when growing food in space, and how could engineers design a solution to overcome it? Use evidence from the video and your own ideas to explain why the solution would be effective.
