Does concentration affect the rate of a chemical reaction? Science scholars observe and control a chemical reaction in an interactive simulation. The resource allows pupils to add atoms to the reaction vessel and monitor the reaction's progress using a sidebar scale.

Instructional Ideas

• Ask the class to form a hypothesis that describes the outcome of the reaction using a certain number of atoms, then test that hypothesis in the interactive
• Assign the interactive as individual practice during the first few days of a chemical reactions unit

Classroom Considerations

• Learners should be familiar with the meanings of concentration and reaction rate; consider holding a brief discussion of both terms before launching the interactive

Pros

• Uses simple graphics, allowing students to better view the progress of the reaction
• The resource operates smoothly and is easy to control

Cons

• None
