The Water Cycle

Center Number 1

Spring 2004

Ms. Wall’s Fifth Grade Class

The Water Cycle

• Today we will be going on an adventure to find out more about the water cycle.

• Hold on to your hats boys and girls, it’s going to be a fun ride!

• Please follow all instructions presented in this center.

The Water Cycle

• Our adventure today is going on a virtual fieldtrip of sorts.

• This during this trip we will be using the internet.

• So please remember all of our computer rules!

The Water Cycle

• We have been talking about the water cycle in class for the past few days.

• Over the next few we will be using centers to do a bunch of different centers that are related to the water cycle.

The Water Cycle

• First stop on our trip is a case that needs to be investigated.

• Think about the case and try to answer the question presented.

• Be logical. Think about what you already know. We did the experiments on this stop yesterday.

• Good luck detectives!!!

The Water Cycle

• So how did you do detectives?

• On your paper tell me what you thought about while answering this question.

• Was your conclusion correct?

The Water Cycle

• Next we will be going to find out more about the water cycle.

• The water cycle is also called the Hydrologic Cycle.• http://ww2010.atmos.uiuc.edu/(Gh)/guides/mtr/hyd/bdgt.r

xml• Please notice how much water the oceans, atmosphere, and

land hold.

The Water Cycle

• Evaporation is the first stop on our trip today.

• Visit this site. Write down the answers to the questions and do the experiments on the tables behind you.

• All of the supplies are located there.

• Then continue with this center, as time allows.

The Water Cycle

• Evaporation is the change of state in a substance from a liquid to a gas.

• When water evaporates it goes into the air.

• For evaporation to take place, energy is required.

• The energy can come from any source; the sun, the atmosphere, the earth, or objects on the earth such as humans.

• Transpiration is another part of the water cycle.

• There is not an activity to do with this element, but you will need to know what happens in this process.

The Water Cycle

• Transpiration is the evaporation of water into the atmosphere from the leaves and stems of plants

• Plants absorb soil water through their roots and this water can originate from deep in the soil.

• Plants pump the water up from the soil to deliver nutrients to their leaves.

• Transpiration accounts for approximately 10% of all evaporating water.

• Let’s think about condensation next.

• Click on the link. Answer all of the questions and do the activity on the page.

• If you have further questions please ask.

The Water Cycle

• Condensation is the process whereby water vapor in the atmosphere is returned to its original liquid state.

• In the atmosphere, condensation may appear as clouds, fog, mist, dew or frost, depending upon the physical conditions of the atmosphere.

The Water Cycle

• Transport is the next element of the water system that we will be looking at.

• There is not an activity for this element. (You do, however, need to know what water does during this stage of the water cycle.)

The Water Cycle

• In the hydrologic cycle, transport is the movement of water through the atmosphere, specifically from over the oceans to over land.

• Some of the earth's moisture transport is visible as clouds, which themselves consist of ice crystals and/or tiny water droplets.

The Water Cycle

• Precipitation is the next stop we are going to make on our adventure.

• Make sure to answer all the questions and do the activity.

• http://www-k12.atmos.washington.edu/k12/pilot/water_cycle/precipitation.html

• Precipitation is when the water that is in the clouds falls to earth in various forms.

The Water Cycle

• Precipitation is the result when the tiny condensation particles grow too large and fall to the earth.

• It falls to the earth in the form of rain, hail, sleet, and/or snow.

The Water Cycle

• Saturation is the next stop on our adventure this week.

• Please answer the questions and do the activities.

• http://www-k12.atmos.washington.edu/k12/pilot/water_cycle/saturation.html

Bramer

The Water Cycle

• Runoff occurs when there is excessive precipitation and the ground is saturated (cannot absorb anymore water). This runoff flows into streams and rivers and eventually back into the sea.

• Evaporation of this runoff into the atmosphere begins the hydrologic cycle over again. Some of the water perculates into the soil and into the ground water only to be drawn into plants again for transpiration to take place.

• Let’s draw some connections with what we have learned.

• You have this worksheet in your packet.

• You may look back at the presentation if you wish.

• Sadly this is the last stop on our adventure.

• Please do the following questions and activities.

The Water Cycle

• Our field trip is over. I hope you all had fun!

• Make sure that all of your papers are in order in your folder and turn it in.

• After you are finished you may read silently.

• Our next adventure is coming soon!
