Water Cycle

  1. What is the water cycle? The water cycle is a cycle that water moves continuously from earth's surface to earth's atmosphere.
  2. Does the water cycle have a beginning or end? The water cycle does not have a beginning nor an end because the water is always getting evaporated and condensed the it turns to precipitation.
  3. Starting with a puddle on a sunny day, describe how water might move through the water cycle and eventually fall back as rain. From the puddle the water would probably be evaporated into the atmosphere. There it will be condensed and turned into precipitation. Then it rains and starts over.

Water Peny Lab

The steps to the procedure is you first make a prediction of how many drops you think the penny will hold. Then you get a penny, glass of water, and an medicine dropper. Put the penny on a flat surface and use the medicine dropper to put drops on the penny. My prediction was 15 drops of water. But I was surprised to find out that the penny can hold alot more. I think this is because there can be different sizes of drops that you put on the penny. The larger the drop the fewer you could get on the penny. The smaller the drop the more you can get on the penny. Also maybe if you held you dropper closer to the penny you can get more on the penny.
