Select the liquid.

Chalk is a solid. You can easily break chalk into pieces. But each piece will still have a size and shape of its own.
Water droplets are a liquid. A liquid takes the shape of any container it is in. If you collect water droplets in a bucket, they will take the shape of the bucket. But the water droplets will still take up the same amount of space.
A spoon is a solid. You can bend a spoon. But it will still have a size and shape of its own.
A pair of dice is a solid. A solid has a size and shape of its own. When you roll a pair of dice, the dice have a shape of their own. They are still cubes when they stop rolling.
