Why does sugar disappear in water?
Sugar doesn't really vanish. It breaks into tiny bits too small to see!
Pip’s answer
- Sugar doesn't really vanish. It breaks into tiny bits too small to see!
- Busy water bits bump the sugar and pull its pieces away, one by one.
- The tiny sugar bits spread all through the water, hiding between water bits.
- Ooh, the sugar is still there, just too small for your eyes!
For grown-ups
Sugar dissolves: water molecules surround individual sugar molecules and pull them away from the crystal. The sugar spreads evenly through the water as molecules too small to see. It's still there, which is why the water tastes sweet. Warm water dissolves sugar faster.
Ask your child: How can we prove the sugar is still in the water?
