Reaction Rate Lab: experiment guide

This browser-based kinetics lab helps you explain how temperature and concentration influence reaction speed. Designed for Grades 8–12, it turns an abstract idea into a model you can control, measure, reset, and test without signing up.

What you can investigate

Explore Temperature, activation energy, concentration, half-life by changing the available controls and comparing the model’s visual and numerical evidence. Try one variable at a time, then combine changes to test a stronger explanation.

How to use this simulation

  1. 1Read the mission and make a prediction before moving a control.
  2. 2Change one variable so its effect is easier to identify.
  3. 3Run the model and record a value, pattern, or visible change.
  4. 4Reset, test a different setup, and explain the result from evidence.

For students, teachers, and independent study

A typical investigation takes 7–12 min. Use it as a lesson demonstration, a guided inquiry activity, a homework experiment, or a quick review. The simulation runs in a modern web browser and does not require an account.
