Life Cycle of a frog

The children are watching a video clip on the life cycle of a frog. Frogs do not fertilize their eggs internally like chicken. They fertilize them externally. First, the female frog will lay her eggs in a corner of the pond, among the stones. The male frog will find them and fertlize all the eggs together. The eggs are protected by a layer of jelly like substance and left on their own ! Hopefully, some of them survive...
