States of Matter 3D Lab: experiment guide

This browser-based 3d simulation helps you compare particle motion and spacing in solids, liquids, and gases. 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 Particles, phase change, temperature, pressure 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

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

For students, teachers, and independent study

A typical investigation takes 6–10 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.

Level: Beginner
