Science
Rosalie watched a scientist shake a clear cube filled with many small white spheres, which moved inside as the cube was shaken. The demonstration used the spheres’ motion to represent how atoms can vibrate and how energy is connected to movement. Rosalie saw that shaking caused the particles to move, helping make an invisible scientific idea easier to picture. The activity introduced a simple model of particle motion and energy.
Tips
Tips To extend the idea, invite Rosalie to draw the cube before and during shaking, using arrows to show how the spheres moved. Compare gentle and stronger shaking with a safe container of large beads, then describe how the movement changed. Make a simple particle-motion model with paper dots and discuss how a model represents an idea without being the real thing. Finish by asking Rosalie to explain the demonstration in a few sentences or teach it to someone else.
