Educating for Sustainability
UNIT: Wastewater Context for Matter and Its Interactions
LESSON: Molecular Structure of Water.
Part of a series of lessons in a unit called Wastewater Context for Matter and its interactions. Designed for middle school physical science, students will come to understand the uniqueness of water through the properties that emerge from its polarity.
Suitable for Grades
Satisfies Academic Standards:
MS-PS1-1 - Atomic Composition
Sustainable System Focus:
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.
- Matter is composed of elements and molecules whose properties are determined by their structure
- Water’s properties are determined by its molecular structure: water is polar
Time needed: .5 class period
- After the lesson activities are show the Powerpoint slides to explain polarity and how it affects the properties of water
- 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
- I have students draw the water molecule in their notebooks with the positive an negative charges on the appropriate ends of the molecule
