Guiding Activity~ Krista Miller

How do humans affect ecosystems?

Objectives assessed: The student(s) will be able to demonstrate understanding that: • Some changes to ecosystems occur rapidly over a period of a few years or less. • Most organisms in an ecosystem are adapted to seasonal changes. • Natural disasters such as a volcanic eruption are short-term changes that can damage an ecosystem. • Human activity causes many short-term changes in an ecosystem. • Changes may be harmful or helpful to the organisms living in an ecosystem. • Human changes to an ecosystem include changing land use and introducing pollutants.

- First, read through the glossary terms on the left of the page. This glossary is exciting because it’s interactive!

- Then, read Human Effects in Ecosystems (click on top left green box) You may read out loud, taking turns or silently to yourselves. As you read, use your Kidspiration O-W-L chart to take notes about what you observe, wonder and learn. You will use this document in a modified way.

Good luck! Next, to show your learning, use Glogster, voicethread, or kidspiration to draw or write about at least 3 changes that can happen in an ecosystem over one year.
