What is a Cycle?: An Explanation by 2nd Grade Scientists
A cycle is something that repeats over and over. An example of a cycle in nature is an animal’s lifecycle. A Monarch Butterfly lays its eggs on Milkweed leaves. The caterpillar hatches and eats the egg. Next, the caterpillar grows and grows. Then, it climbs on a steady leaf and forms a chrysalis. The Monarch Butterfly comes out of the chrysalis. Now this butterfly will lay eggs, so it all starts again.
Another kind of cycle is the water cycle. First, water goes up to the sky. This is called evaporation. Then it cools and makes clouds. This is called condensation. Finally, the cloud gets so filled with water the rain falls down. This is called precipitation. Then it starts all over. This makes it a cycle.
Nice job writing the facts about a water cycle and a lifecycle. We noticed your hard work. We are learning about this information in science, too! We like how you took the time to put it on our school website.
Thank you,
