Chart the Changes

In science class, you have been learning about ecosystems and how humans can change them. In this activity, you and your family members will create a poster that shows the ways humans can affect ecosystems.

Positive Changes Negative Changes



Ask an adult to help you create a two-column chart like the one above on a large sheet of posterboard. Label one column “Positive Changes” and the other column “Negative Changes.” Cut out pictures from old magazines that show some positive and negative changes that humans have made to ecosystems. If possible, describe how each negative change could be made into a positive change.


What could you do with your poster to make people aware of how human activities impact the ecosystem? How have human activities impacted the ecosystems in your town or city?
