The ten-level path
Mix two colors, then three. Tap the sun for one water-cycle step, then all four: sun, cloud, rain, puddle. Predict float or sink, drag many objects, pick ingredients for a bubbly reaction, then a two-step and three-step guided experiment.
Play, then try it in the kitchen
The game is a rehearsal. After mixing virtual red and yellow, mix paint or food coloring for real. After sink or float, fill a tub. The screen should send kids back to water, ice, and questions.
