Grade Two - California Science Standard:
2. Plants and animals have predictable life cycles. As a basis for understanding this concept:
b. Students know the sequential stages of life cycles are different for different animals, such as butterflies, frogs, and mice.
The frog is an amphibian creature that lives in areas that are moist. Frogs do not cause harm to anyone. Its favorite eatable treat are flies and small insects. They are green and covered in jellylike texture because of their overexposure to pond water and humid climate.
The life cycle of a frog begins with the egg or spawn (clump of eggs). They are laid big so that they are well protected from other animals who are trying to eat them. Next, the egg splits into two cells, in which split into another two pieces, etc. Each egg will end with many split cells inside of it. Then, the cells form an embryo, where the rest of the body parts are completing their development. The embryo will last for about twenty-one days. After those days are over, the embryo departures its egg shell and forms into a tadpole (baby frog) in the weeds of water. Tadpoles stay close to the weeds for around three weeks. The tadpole transforms into a froglet and continues to nitrate itself with what nature provides for it. After many weeks have passed when the froglet has been freed from its shell, it develops itself into a fully developed adult frog in nature. Therefore, the life cycle of the frog is complete.
