Ms. Brittain’s 3rd Grade Class Science The Water Cycle Ms. Brittain’s 3rd Grade Class Science Forward

Introduction We are going to be learning about the water cycle! I will teach you about how water goes through the water cycle and the steps that it takes. We will also talk about its effects on the environment and how it affects us.

Navigation This slide will help you navigate through the power point. As you can see there is a previous and next button There is a main menu button Click on each of these to go through the presentation Also there is a main menu slide that you will need to click at the end of each lesson to learn more about it. There is also a test at the end! So pay attention! Good luck!

Sections: Water is Everywhere! Evaporation and condensation Water vapor in the air, humidity Clouds: cirrus, cumulus, stratus Precipitation and groundwater Test Review

Main Menu Remember: Go in sequential order for each lesson. Lesson 1 Testing Section

Lesson 1: Water is Everywhere Think about how much water you use a day, and where it comes from… Shower Washing hands Going to the bathroom Drinking water Cooking Helping plants Feeding pets

Water Cycle: The way in which water moves on and around the earth Check out this picture of a water cycle and go through it on the picture.

Is there more land or water covering the earth’s surface? Look at these maps to decide Water Land Land Water

These are the 4 major bodies of water You are Here These are the 4 major bodies of water Pacific Ocean Atlantic Ocean Indian Ocean Arctic Ocean

You are finished with lesson 1 please go on to the lesson 2. Water Land Most of the earth’s surface is covered with water. About 3/4 to be exact. Most of the water is found in oceans and glaciers. Only a very small percent is found in rivers, streams, and lakes.

Lesson 2: Evaporation and Condensation What happens when you boil water on the stove? Does it get colder and freeze or get warmer and turn into gas? This process of water changing from a liquid form to a gas form is called evaporation. It happens when water reaches a certain temperature. This gas is called water vapor. Droplets: tiny drops of water Water vapor

Water Evaporation in jars

EVAPORATION! Jar 1 was left open over night and jar 2 was covered. The difference between the two of them is that jar 1’s water level lowered over night while jar 2 stayed the same. The reason for this is EVAPORATION!

Condensation: when water vapors cool and turn back into water droplets When condensation happens, water vapor will rise and cool, and collect around bits of dust to form a cloud The picture to the right shows evaporation and condensation in the water cycle

Now that evaporation and condensation have occurred, the water is trapped in the clouds

You are finished with lesson 2 please go on to lesson 3. OPPOSITES! EVAPORATION VS. CONDENSATION When water vapor cools and turns from a gas form into water droplets When water changes from a liquid for to a gas form You are finished with lesson 2 please go on to lesson 3.

Lesson 3: Water Vapor in air, humidity Water vapor rises in the air to the clouds. If there is a lot of water droplets or water vapor in the air, we call that moisture. Humidity: the amount of moisture in the air

How can we tell when its humid out? When it feels sticky Sweating and hot There will be dew and water droplets on things outside like windows.

Places that AREN’T Humid Places that ARE Humid Places that AREN’T Humid Places that are Humid Beach After you get out of the shower Green room, butterfly room Places that aren’t humid Desert Dehumidifier You are finished with lesson 3 please go on to lesson 4.

Lesson 4: Clouds: cirrus, cumulus, stratus Clouds: clusters of water droplets all together 3 types of clouds Cirrus Cumulus Stratus

Cirrus cloud: High in the sky Indicates good weather Made of ice crystals

Cumulus cloud: Big, white puffy clouds Like cotton Good weather Low level

Stratus cloud: Storm clouds Gray in color Low level

Fog A cloud that touches the earth Ground level Can impact driving and getting around

You are finished with lesson 4 please go on to lesson 5. Clouds are made from a buildup of water droplets When the cloud gets too heavy to hold all of the water droplets, the precipitation falls back to the earth in different forms.

Lesson 5: Precipitation, Groundwater The falling of water from the sky in the form of rain, sleet, snow, or hail.

Groundwater: Water that is under the ground After precipitation occurs, the ground soaks up the water and stores it underground.

Rain: Precipitation in water droplet form

Hail: Precipitation in ice form

Sleet: Precipitation that is a mix of water and ice

You are finished with lesson 5 please go on to the testing section. Snow: Frozen precipitation, comes down in white flakes

Click on the answer you think is correct to find out the right answer. Question 1 What happens when a cloud gets too heavy to hold all of the water droplets? 1. The cloud turns to a grey color 2. The water falls back to the earth 3. Condensation occurs Click on the answer you think is correct to find out the right answer.

Not Quite… Clouds will turn grey when they have too much water in them, or if it’s about to storm. That type of cloud is called a stratus cloud. This does mean that precipitation will occur.

You’ve got it! Great job! The water falls back to the earth in some form like snow, sleet, hail, or rain. CORRECT!

Try Again Condensation is when water vapor cools and turns from a gas into water droplets. It’s not when the water droplets fall back to earth.

Question 2 What Ocean are we in Pennsylvania closest to? 1. Atlantic 2. Pacific 3. Indian

Great Job Wohoo! You got it right. The east side of the US borders the Atlantic Ocean.

So close… The pacific ocean does border the US, but it’s not on the east coast. It is on the west coast next to California

Maybe next time… The Indian ocean is in-between Africa and Australia

Question 3 Which type of cloud is big and puffy like cotton? It also means good weather and is low level? 1. Cirrus 2. Fog 3. Cumulus

Nice Try! A cirrus cloud is one that is high in the sky and is white but it is made up of ice crystals.

Not Quite… Fog is a cloud that is on ground level. This is the type of cloud that you can see right in front of you.

Woohoo! You got it! A cumulus cloud looks like cotton candy and is on a low level. It looks like cotton. CORRECT!
