This Reaction Between Hydrogen and Oxygen Molecules interactive also includes:
When molecules of hydrogen and oxygen are combined, how does water form? Science scholars observe changes in kinetic and potential energy during a chemical reaction in an interactive. The resource features easy controls that allow users to add energy to the reaction vessel and observe molecular interactions at different points in the reaction. A handy graph of energy versus time records changes throughout the reaction.

Instructional Ideas
- Use the interactive to allow students to create a model that illustrates changes in energy within a chemical system
- Instruct the class to focus on moments where bonds form or break and have them record their observations on the energy graph
Classroom Considerations
- Schedule time in the computer lab for individuals to use the interactive
- Enable the legend to help pupils track changes in kinetic and potential energy
Pros
- The interactive has controls that allow users to search forward and backward during the reaction to view specific interactions between atoms and molecules
- Adding energy to the reaction helps learners understand and view how bonds break
Cons
- None
