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

• All organisms have basic needs.

• Basic needs may include air, water, food, and light.

• Earth has many different environments which support many different types of life.

• Organisms can only survive when environments support their basic needs.

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