This is a simulation, not a quiz. You answer by trying things and watching what happens.
Our question
What can you investigate in Reaction Lab to distinguish an observable material change from a change in position or arrangement?
Getting the simulation ready…
- 1Change one thing
- 2Say what will happen, then run it
- 3Finish: say what you found
What counts as evidence- Build a claim and connect it to one result from your trial.
