Field notes
The homepage lays out a repeatable sequence: invite a prediction, demonstrate, then compare one change. The nine labs range from bridge triangles and balloon-car motion to distinguishing an egg’s cushioning from slowing its fall. The parent section also connects the screen exercise to a short activity at home, with notes about the limits of the computer model.
