One of the most interesting things you can do for special study is to collect some frogs’ eggs from the pond and watch them grow into tadpoles and on into frogs. There are glass vessels made particularly for such study (an ordinary glass jar will do). If you can afford a small glass aquarium, get one and with a few green water plants put in a few minnows, a snail or two, a young turtle, water-beetles, and frogs’ eggs, and watch them grow.
