  1. The town of Elm Ridge burns less coal and gas after adding solar panels. Which resource does this keep cleaner?

    • The air
    • The ocean
    • The soil

  2. The people of Maple Street share a garden, fix the playground together, and help out at each other's shops. What are the people of Maple Street?

    • One person acting alone
    • A community, because they live and work together
    • A nature reserve, because it has plants

  3. Trees soak up carbon dioxide from the air and give animals a home.

    Circle one:   True   False

  4. Solar panels help the environment because they:

    • Convert sunlight into electricity
    • Store rainwater for drinking
    • Filter dirty air using plants

  5. Look at the graph. Which community group planted the most trees?

    RiversidePark120Oak St.School85GreenValley150
    • Green Valley
    • Riverside Park
    • Oak St. School

  6. Look at the tree planting chart from the lesson. Green Valley planted 150 trees and Oak St. School planted 85. How many more trees did Green Valley plant?

    Answer: ______________

  7. Riding a bike instead of driving a car is one small action that helps protect the air.

    Circle one:   True   False

  8. Why do communities use science ideas when they choose a project to protect resources?

    • To make the project cost more
    • Because science ideas sound fancy
    • To figure out what will actually work

  9. Three community groups planted trees last spring: Riverside Park planted 120, Oak St. School planted 85, and Green Valley planted 150. How many trees did they plant in all?

    Answer: ______________

  10. If most families in a town ride bikes for short trips instead of driving, what is the most likely result?

    • The town runs out of bikes
    • Nothing changes at all

  1. The air · Burning less coal and gas means less smoke and pollution going into the air.
  2. A community, because they live and work together · A community is a group of people who live and work together, and the people of Maple Street do exactly that.
  3. True · That is right, and it is why tree planting projects help both the air and local wildlife.
  4. Convert sunlight into electricity · Solar panels turn sunlight into electricity, so less fossil fuel needs to be burned.
  5. Green Valley · Green Valley planted 150 trees, the tallest bar, so it planted the most.
  6. 65 · Subtract to find the difference: 150 - 85 = 65 more trees.
  7. True · Bikes burn no gas, so every car trip swapped for a bike trip puts a little less pollution into the air.
  8. To figure out what will actually work · Science ideas help the community test and choose plans that really protect water, forests, or air.
  9. 355 · Add all three groups: 120 + 85 + 150 = 355 trees planted by the community.
  10. Less gas is burned, so the air gets cleaner · Many small swaps add up: a whole town of bike trips instead of car trips means much less gas burned and cleaner air.
