WELCOME TO YOUR SCIENCE WORKBENCH
Observe closely.
Let the evidence lead.
Explore matter, energy, and chemical reactions through interactive experiments. Pause, replay, and investigate at your own pace.

CHOOSE YOUR INVESTIGATION
Use the station named in your study guide or test.
Look inside matter. Compare properties, particles, and changes in a substance.
Follow the evidence as heat moves, temperatures change, and materials respond.
Examine chemical changes, track atoms, and investigate open and closed systems.
Working on your study guide? Open the numbered study models for questions 1–25. Run a trial, pause to inspect the evidence, then record your observations.
Bring the lab to life. Enable sound or raise the volume in a simulation. Use Test sound to check your speakers. Headphones work well in class.
