Procedure
1. Take one ice cube and place it in the saucepan. Observe
the colour of the ice and press it with your fingers. Does it
deform?

2. Take another ice cube, place it in the saucepan, and
observe its shape. Transfer the ice to the jug and observe
its shape over a short period. Did the shape and size of the
ice change after being placed in the jug?
3. Light the stove, then place a saucepan with another piece
of ice on the stove. What do you observe?
4. Place another piece of ice from the ice box in the melted
water. What did you notice?
5. Record the results of your observations for each step.
6. Take a piece of ice from the ice box and place it on a flat
surface, such as a tray. Gently tilt the surface and note the
observation. Does the ice flow like liquid water?
Results
Water in its solid state (ice) is colourless, firm when pressed,
maintains its shape regardless of the container it is placed
in, and does not flow like liquid water. Solid ice floats in liquid
water, and when exposed to warmer conditions, it melts into
liquid water.
Conclusion
The experiment confirmed that water in its solid state is firm,
retains a definite shape and volume, and does not flow like
liquid water.
