Lesson Worksheet: Changing Environments Science

In this worksheet, we will practice describing measures humans can take to help them survive in their environment, how they can change their environment to meet their needs, and the effects this has on other organisms.

Q1:

Read the passage about caribou and warblers in Denali National Park and Preserve.

Denali National Park and Preserve is in Alaska, United States. There are glaciers in the park. The glaciers are melting earlier each spring because the climate is getting warmer. Humans have caused the climate to get warmer.

Melting Glacier

The melting glaciers make puddles. Mosquitoes like to lay their eggs in puddles. This means there are more mosquitoes.

Mosquito on water

Caribou also live in the park. The mosquitoes make them stressed. Because there are more mosquitoes, there are now fewer caribou in the park.

Caribou

Yellow-rumped warblers also live in the park. They eat mosquitoes. Because there are more mosquitoes, there are now more warblers in the park.

Yellow rumped warbler

Humans want to lower the number of mosquitoes in the park.

Fill in the blanks: This will make the number of caribou and the number of warblers .

  • Ago up, go down
  • Bgo down, go up
  • Cstay the same, go up
  • Dgo down, stay the same

Q2:

Antarctic Melting Glacier

The melting glaciers make puddles. Mosquitoes like to lay their eggs in puddles. This means there are more mosquitoes.
