How electricity is important to me

How Electricity Is Important to Me

  • Electricity is important to me because without it most people would have to do things the old fashioned way and kids aren't used to that.

  • Electricity is important because I use it everyday. Classrooms could not have light without electricity. So many things use electricity it would be hard to let them go.

  • Electricity is used for so many things and I am very grateful.
