Activity 9:
Seasonal Vegetation Changes
Level: Grade 5-8, but easily adaptable for older or younger students
Learning Objective: Students will compare vegetation maps in January
and July. They will see that some regions are green all year long,
but other regions (in the Southern Hemisphere) are greener in January,
and yet other regions (in the Northern hemisphere) are greener in
July. Some regions (deserts and polar ice regions) are green neither
time.
Specific Science Content Standards
- Changes in earth and sky
- Populations and ecosystems
- Structure and evolution of an earth system's history
- Geography: Using maps to acquire and process data
Earth Update: Biosphere
Introducing the activity:
Tell students that measuring the color of the Earth can be used from
space as a way to tell how healthy the Earth is. This can be done
both to help farmers grow crops and to observe how deforestation has
affected the Earth. As a follow-on, you can download the most recent
vegetation maps in the "latest images" section of the Biosphere module,
to compare today's data to an average January or July.
