Content Connection

Once students are familiar with molecules and compounds this lesson focuses on the unique properties of water that are the result of it molecular structure.


Scientific Principle(s)

  1. Matter is composed of elements and molecules whose properties are determined by their structure


  1. Water’s properties are determined by its molecular structure: water is polar

Lesson Plan



  1. Powerpoint slides



  1. Notebooks


The Plan

Time needed: .5 class period

  1. After the lesson activities are show the Powerpoint slides to explain polarity and how it affects the properties of water

  2. It may also be a good time to re-show the properties of water video. Students will see it with a whole different perspective now

  3. I have students draw the water molecule in their notebooks with the positive an negative charges on the appropriate ends of the molecule
