This Water is a Polar Molecule lesson plan also includes:
A water strider is a bug that taps into the attraction between the positive and negative ends of water, allowing the bug to walk on water. Learners view short videos showing polar characteristics of water. Pairs then discuss what polar molecules are, analyze water molecule models, and complete a hands-on activity to develop their understanding of how polarity determines some characteristics of water. The first in a series of nine activities.

Instructional Ideas
- Place learners in pairs for the entire lesson in order to facilitate better discussion during video portion and efficiency during the hands-on activity
Classroom Considerations
- Needs include water molecules made of Styrofoam balls and toothpicks (from a previous activity); teachers can make these if previous activity was not completed
- Pairs mark the water molecule models with permanent marker so they cannot be re-used; consider asking helpers to make the models before/after school
Pros
- Includes pre-scripted questions for teachers to ask during videos
- Linked videos are short, engaging, and effective, especially for visual learners to help them fully understand the concepts
- Lesson is set up in the 5E model format
Cons
- None
