  1. The Water Cycle Introduction Lesson Quiz

  2. Introduction Hello everyone! Subject- Science Grade Level- 2nd Objective- students will be able to: • Recognize the steps of the water cycle • Name and explain what each step of the water cycle does Ohio Educational Content Standards- Earth and Space Sciences: • Water is present in the air • http://www.ode.state.oh.us/gd/templates/pages/ODE/ODEGoogleSearch.aspx?page=221&query=science%20content%20standards&start=0&OriginatingURL=/gd/template Ohio’s Academic Content Standards-Extended Science p.2

  3. Lesson This lesson will teach students parts of the Water Cycle and how they work together. Once students complete the lesson, they can go back and review the lesson again or go on and take the quiz. Students can either access the quiz from the homepage or use the arrows and go straight to the quiz from the lesson. Good luck!

  4. Introduction to Water Cycle Although water is all around us, there is only a limited amount of it on Earth. Water rotates through the air down to the Earth and back up to the air again by what we know as the “Water Cycle”. The water cycle is made up by a few steps: 1. Evaporation 2. Condensation 3. Precipitation 4. Collection

  5. Evaporation Have you ever noticed a boiling pot of water has “fog” or “clouds” hovering above it? Those “clouds” are what is known as water vapor or steam and is a function of evaporation. In nature, evaporation occurs when the sun warms up the water in rivers, lakes, oceans, or streams and causes the water to become so hot that the water that goes into the air is turned into water vapor or steam.

  6. Condensation When you look outside and see those big fluffy clouds, what do you think those clouds are made of? The clouds may look like big cotton balls or giant cotton candy, but they are actually made of water! Water vapor in the air gets cold, and when it does, this causes the gas form of water to turn back into liquid which forms those big clouds we see in the sky.

  7. Precipitation Do you ever wonder why it rains, snows, hails, or sleets? Whenever water has condensed so much that the air cannot hold it anymore, the water vapor filled clouds become heavy and water falls back to Earth in the form of rain, snow, hail, or sleet. This process is known as precipitation.

  8. Collection Now that the water has fallen back to Earth, where do you think it all goes? Precipitation can fall back into lakes, oceans, streams, rivers, or even on land. The water that falls on land soaks into the Earth and becomes “ground water” that plants and animals can use to drink. If the water overflows in the soil, it may fall back into bodies of water and the water cycle repeats ALL OVER AGAIN!
