Dust Across the Sky

Open to everyone until Friday, October 2

To keep it, print it while it is open.

A huge cloud of dust can block sunlight for many months. Without enough light, plants die, and animals that eat plants or other animals run out of food.

In the picture

  1. A thick dust cloud: it covers the sky and blocks most sunlight.
  2. A wilted fern: it droops because it cannot make enough food without light.
  3. A tree with shriveled leaves: its leaves dry out and fall as light fades.
  4. A large dinosaur: it searches a dim landscape for plants or prey as food becomes scarce.

Examples

  • After a big volcano, ash in the sky can make skies dim and cool for a while.
  • If a room plant is kept in a dark closet, its leaves turn yellow and it stops growing.
