A solid keeps its own shape. A stone, a spoon and a toy block stay the same shape wherever you put them.
A liquid can be poured. It takes the shape of whatever it is in: water in a glass looks like the glass, water in a bowl looks like the bowl.
A gas spreads out to fill all the space it can. Air is a gas: you cannot see it, but you can feel it when the wind blows, and it fills up a balloon.
Water can be all three! Freeze it and it becomes solid ice. Warm the ice and it melts back into water. And ice floats on water.
Experiment: The ice cube race
- Guess: where will the ice melt fastest?
- Put one ice cube on each plate and put the plates in different places. Hold one cube in your hand on a tissue.
- Every 10 minutes, look: which ice cube is smallest?
- When one has melted completely, write down where it was. Which one melted last?
| Where? | I guess (1st, 2nd…) | Order it melted |
|---|---|---|
| Sunny window | ||
| Shade | ||
| My hand | ||
| Warm place |
