Frogspawn

We’ve spotted frogspawn in our local pond! It’s come very early this year, but the jelly-like substance is definitely being produced. Kids are fascinated by the stuff, and no wonder, it looks positively alien. Collect some if you have space outside to keep at home (follow the instructions here), or keep an eye on a batch in a park nearby. Perhaps you could track the spawn’s progress daily; watch as the little black dots grow bigger and bigger, eventually hatching into tadpoles. Then see the transformation from wiggler to little frog.
