Water Cycle By Vanessa Rucker

 Water is a compound of two elements, hydrogen and oxygen. Each water molecule contains two hydrogen and one oxygen atoms. Water can be liquid, solid, or gas. It can evaporate into vapor or freeze into ice. Most of the Earth's surface is covered by water. The water cycle is the constant movement of this water. The water from rivers, lakes, and oceans evaporates into vapor. The vapor rises and forms clouds. The water then falls as rain, hail, or snow and the cycle begins again. What is Water?

Lyrics for the Water Cycle Jump You should know that it all starts with the sun Evaporated oceans and lakes We're here to tell you about Rain Rain The water cycle makes it Rain Rain Evaporation makes it Rain Rain Condensation makes it Rain Rain Sun heats the ocean, molecules go round and round Go much faster they begin to jump up and down Become water vapor flying up to the sky Get together, form a cloud My, oh my I'm talking about condensation You know it's fly Water from the earth evaporates to the sky And what consenses must come down just the same The Water Cycle Jump

When it comes down, it's riggida riggida riggida rain You know rain is precipitation Collects on stuff to evaporate in Then it starts all over and that's a fact That's the water cycle, you can believe that Rain Rain The water cycle makes it Rain Rain Evaporation makes it Rain Rain Condensation makes it Rain Rain Your brain is on vacation If you don't know about precipitation The water cycle never stops you see C-Y-C-L-E That's the cycle, and you know it's like that The Earth recycles water, you know it's not whack It's all natural, it's not coincidental Keep the water clean because that's environmental Rain Rain The water cycle makes it Rain Rain Evaporation makes it Rain Rain Condensation makes it Rain Rain Peace, I'm outta here The Water Cycle Jump

Water on Earth is always changing. Its repeating changes make a cycle. As water goes through its cycle, it can be a solid (ice), a liquid (water), or a gas (water vapor). Ice can change to become water or water vapor. Water can change to become ice or water vapor. Water vapor can change to become ice or water. The Water Cycle

In the water cycle, water from oceans, lakes, swamps, rivers, plants, and even you, can turn into water vapor. Water vapor condenses into millions of tiny droplets that form clouds. Clouds lose their water as rain or snow, which is called precipitation. Precipitation is either absorbed into the ground or runs off into rivers. Water that was absorbed into the ground is taken up by plants. Plants lose water from their surfaces as vapor back into the atmosphere. Water that runs off into rivers flows into ponds, lakes, or oceans where it evaporates back into the atmosphere. The Water Cycle

 Evaporation  Condensation  Precipitation The Three Forms of Water

 Evaporation is when the sun heats up water in rivers or lakes or the ocean and turns it into vapor or steam. The water vapor or steam leaves the river, lake or ocean and goes into the air. Evaporation

Do Now: Ask the students to draw a diagram and label the part of the water cycle on a blank sheet of paper. Lesson Plan - Evaporation

Island in a Bottle Water Cycle Experiment  In the morning (on a hot day), fill the soda bottles with about 2 cups of sand (small pebbles or aquarium rocks).  Fill the soda bottles with water, so that when tipped on the side the sand and rocks come to the surface, like a small island.  Secure the lid on the bottle.  Set the bottle in the sun and use 4 large rocks or pebbles to hold the bottle in place sideways.  Make a dot with a black permanent marker on the side of the bottle to show where the water level is.  Measure the water level and make a note in your science notebook. Activity

 Have the students make a hypothesis. What do they think will happen to the water in the bottle?  Each day, the students visit their water bottles (still in the sun), measure the water level and take note on any changes they see.  Results:  As long as the sun is directly on the bottles, students will observe evaporation (the amount water to measure with the ruler is decreasing), condensation (on the sides of the bottle) and possibly precipitation (the water dripping back down from the side of the bottle). The sand or pebbles are similar to what mountains do, holding water storage beneath the surface and in streams. Then, falling into the ocean. Activity

 Water vapor in the air gets cold and changes back into liquid, forming clouds. This is called condensation. Condensation

Today, we are going to complete an experiment where you will see water molecules condense into a cloud in the bottle. When you squeezed the bottle the air pressure in the bottle increased which raised the temperature. The warmer air caused the water in the bottle to evaporate (it became water vapor) and you could not see it. When you let the bottle pop out, the air pressure in the bottle decreased along with the temperature. This caused the water molecules to condense into a cloud. Lesson Plan

Precipitation Precipitation occurs when so much water has condensed that the air cannot hold it anymore. Water particles in the clouds may become too heavy to remain in the air, and are pulled to the earth's surface by gravity as precipitation. The main types of precipitation include rain, snow, hail, and sleet.

Lesson Plan  Objective: Identify the four types of precipitation.  Take out them following worksheet. In your own words, describe the four types of precipitation.

 Evaporation  Condensation  Precipitation  Infiltration  Runoff  Storage Six Stages of the Water Cycle – Find a picture of the 6 stages

Field Trip – Manhattan Adirondacks  Field trips are a great way to complete a unit. It allows the students to take the information they have learned in the unit and see it in action.  NYC is full of several parks.  The Central Park Conservancy offers a lot of opportunity for students to experience science through nature. They offer guided tours for several exhibits.  The tour that I feel will be the best to describe the water cycle is called “Manhattan Adirondacks” where Olmsted and Vaux designed the North Woods to replicate the forests of the Adirondack Mountains, with their crystal streams, tumbling cascades, rustic bridges and picturesque pools right in New York City’s backyard.

 I used the pictures to help the students learn new vocabulary words. The pictures helped them relate a new word to something they already knew or have experienced before. I used the video to hook the kids into the concept of the Water Cycle. The video leads to a song about the water cycle. The beat is catchy and it captured the students attention. How did I use this presentation?
