Instructional Ideas
- Have pupils describe what is happening in the solution when they see an increase in potential energy
- Expand the lesson to include the effects on kinetic energy within the system as a result of decreasing potential energy
Classroom Considerations
- A discussion of potential energy in chemical systems would help prepare the class to use the interactive
Pros
- Resource can show interactions between atoms and molecules, which allows for a more in-depth look into solution chemistry
- Water and solute particles are easy to identify and keep track of throughout the interactive
Cons
- None
