Reflecting both the NGSS and NSES standards, this lesson from the Essential Science series covers the following key concepts:

• There are many different kinds of ecosystems.

• All living things interact with their ecosystems in various ways.

• Scientists call a large, regional ecosystem a “biome”.

• When ecosystems change, creatures must adapt or move away in order to survive.

Note that every lesson in this series also offers multiple options for “hands-on” activities, and alternative assessments of varying difficulty.
