3. With your partner, plan for and construct a food web.  You may use Inspiration, Kidspiration, or the shape and arrow tools in MS Word to create the food web.

Check out the rubric so that you know what is expected.

Criteria for the food web include:

• There must be at least ten living things in your web.
• There must be at least two producers, two consumers, and one decomposer.
• All of the plants and animals  must be from the same habitat/biome.
• Your food web must contain pictures and names of each living thing.
• The arrows must point from the living thing being eaten to the living thing doing the eating to correctly represent the energy flow from one living thing to another. 

This MS Word template will help you with planning.  Download it and save it into your directory.  Make sure you save your changes.  Discuss your plan with Mrs. Dell before you begin constructing the food web.
