My tween found clutch of frog eggs in a soon to dry out puddle in the field next to our house. she saved them, what to do next, advice?

You can relocate the eggs to another puddle or you can bring them home and wait until they hatch before relocating them. Use pond water or bottled water only, but no tap water if you choose to bring them home. Or you can leave the eggs where they are. It is natural selection at work. If frogs do not place eggs where they are likely to survive, then the parent frogs don't leave their genes and only frogs that know where to lay eggs will leave their genes to future generations.

Scoop them up, along with as much of the puddle water as you can get. Keep them inside in good light. Eggs laid in puddles usually hatch quickly into little black tadpoles and a very few of them metamorphose into toads. One hint that you have toads - - the eggs will be in strings, rather than globs.

Put them back before it dries up.

Nature  will put them in hibernation, until the next season.

Throw them into the river
