Grammar help for a 6-year-old — Frogs: 'Frogs live on land, but lay eggs in water that hatch into tadpoles'

Original sentence: Frogs live on land, but lay eggs in water that hatch into tadpoles.

Is it correct? Yes, it is mostly correct, but it can be clearer. Right now the phrase 'that hatch into tadpoles' could look like it is describing the water, and water does not hatch. We want it to be clear that the eggs hatch.

Clearer ways to say it:

1. Frogs live on land, but they lay their eggs in water. The eggs hatch into tadpoles.
2. Frogs live on land, but they lay their eggs in water, and the eggs hatch into tadpoles.
3. Frogs live on land but lay their eggs in water, which hatch into tadpoles.

Simple explanation for a 6-year-old: Say it in two short sentences: 'Frogs live on land. They lay eggs in water. The eggs hatch into tadpoles.' This makes it very clear that the eggs hatch.

If you want one sentence, the second option above is the clearest: 'Frogs live on land, but they lay their eggs in water, and the eggs hatch into tadpoles.'
