Cómo se juega
- Heat and cool: set the heater from deep freeze to high and press Start or Pause. The thermometer, graph, pot and particles change together. Press New block of ice to start again.
- Water cycle: set the sunshine, tick Cold weather and press Start to watch evaporation, clouds, rain or snow and rivers; the amounts always add up to the same total.
- Levels: three states, changes of state, thermometers and temperatures, water in daily life, and the order of the water cycle.
Unidad del currículo
Primary science, grade 3: where water goes, boiling, freezing, melting and the three states of water, extended to the water cycle (Jiaoke science, grade 3 volume 1, unit 1).
Para padres y docentes
Heat uses real values (specific heats of ice, water and vapour, 334 J/g to melt, 2260 J/g to boil at normal pressure), which is why the boiling step is much longer than the melting step. Mistakes are grouped by states, visible steam vs vapour, names of changes, thermometer reading, 0 °C and 100 °C, daily life and the cycle order.
Preguntas frecuentes
Is the white “steam” from a kettle water vapour?
No. Water vapour is an invisible gas. The white cloud is lots of tiny liquid droplets that formed when the vapour met cooler air.
Why does melting ice not get warmer while you heat it?
All the heat goes into turning ice into water, so the mixture stays at 0 °C until the ice has melted. Boiling water stays at 100 °C for the same reason.
How does the water cycle work?
The Sun makes water in seas and lakes evaporate. The vapour rises, cools and condenses into droplets that make clouds. Bigger drops fall as rain or snow and flow back to the sea in rivers. The total amount of water stays about the same.
