Expository Writing: Hit the Lights!
Expository writing presents, describes, and explains facts, ideas, and
concepts.
It can be very easy to waste energy. But it can be just as simple to
conserve energy.
Before you begin writing, think about all the things that use electricity
in your school and home.
Now, write a paragraph to tell how energy can be conserved at both
home and school.
Hit the Lights!
There are many ways to conserve energy at school and at home. Saving
electricity is one of the best ways.___________________ ___________
