2. “Today I, Professor Oxygen, am going to teach you about the ten concepts of water.” said Professor Oxygen happily to be teaching yet another class. “Awwwww!” said the class. They were very upset that they had to do another boring lesson in science. “Fine then I will take my friend Rex the raindrop to another excited class that will learn”, the Professor said angrily, “he wouldn’t like a class not interested in him!” “NO, NO! Wait we are sorry we are interested in the ten concepts of rain, now can we see Rex?” said the whole class ready to learn. “Ok, just let me get everything set up first.” he said getting very anxious about today’s lesson. He put his brief case on the table with a thud. He then pulls out a machine and sets it on the table. “There just a few seconds longer.” he said as he fumble around with the water proof camera. The class couldn’t reply back they were so shocked at what this Professor had pulled out of his bag. Just like a magician. He flipped a couple of switches on this giant machine and it clanked and sputtered out black smoke. He ran around the desk to the TV monitor in the back of the room and turned it on. It frizzled alive with bunches of static electricity. Again he quickly ran back to the front of the room grab a remote and pressed it. Suddenly he disappeared with a zap! Johnny stepped forward and asked, “Well, were did he go?” all of a sudden there was a faint sound of someone tapping on glass and asking if anyone was there. Everybody’s head turned to the back of the room were the TV monitor and they saw a tiny little with a mustache glasses and a bright red bow tie. “How did you get into the TV Professor”, the class asked shocked again “, and why are you a rain drop?” “That is a very simple question class. I have transformed into a raindrop by that big machine over there, in the front of the room. It is called a human transformer 2000. It will transform you into anything you want it to!” said the Professor boastfully. “How can we see you through the TV if you’re a raindrop?” asked Johnny “Remember my camera I took out, well I connect it to the TV so you could see everything that the camera sees.” said Professor. “But how can you...” Johnny stared to ask but was rudely interrupted by the Professor. “No more question we have to get on with the lesson for today class.” “What do we do then?” Johnny asked. “Sit back, relax, and take notes”, the Professor said “, here I go.” Suddenly the Professor disappeared into thin air but the camera view started to move. It started getting faster and faster, suddenly the view appeared in the clouds with bunches of other little raindrops. Then this huge rain drop comes forward and started to talk but was too far away so he got closer and closer. Then it says, “Hey! Professor, how’s it been? Long time no see.” “Yes, that's right. How are you doing, Rex.” replied the Professor. “What’s with the camera, doc.” Rex asked. “I'm substituting for a school class and I have to teach them about the ten concepts of water.” the Professor said.

3. “Oh well I don't know that much about that but I'll try.” said Rex. All of a sudden all the little rain drops started to fall down through the clouds. Then the Professor plot onto a string of grass and slid down it to the ground. But Rex wasn't so lucky he fell on the ground with a thud and his arm was missing! It was all stuck to a piece of grass that was hanging upside down! “Aww man, how did my arm do that?” Rex said. “What do you mean Rex? Ohhh that’s what you mean, well when water stick to another surface other than its self it is called adhesion. So when you fell and hit the ground your arm broke and sprayed every were. When it did that it got stuck to the grass which is called adhesion.” said the Professor. “Oh wow your smart doc. But I feel this really big urge to go get my arm back! Wow! Now my arm is back together and its even stronger than it was! What’s up doc why is this happening. ” Rex asked sacred and shocked at the same time. “Well Rex the extreme urge you had to get your arm back is called polarity. Polarity is when your body feels unbalanced and you feel that you need to balance it out so you go out and stick to anything that will give you that balanced out feeling, but you reconnected with your arm to get that balanced feeling back and your body stopped worrying about being unbalanced. Also when you noticed that your arm came back together again and it was just like new, that is called a hydrogen bond. All the little million water molecules that make you up has one big oxygen molecule with two little tiny hydrogen molecules attached to it and when polarity accurse, which we already talked about is the major feeling that your body is unbalanced and you need to connect with something to make it balanced again, the tiny hydrogen molecules came together and held hands to replace your arm back where it’s supposed to go. Last but not least when your came back together that is called cohesion. Cohesion is when water sticks to itself.” explained the Professor. Suddenly the ground felt like it was sliding out from under the Professor and Rex. “Uhhh! Hey doc,” shouted Rex over the howling wind, “if I’m correct I think the ground is moving out from under us.” “Now, Now don’t be silly Rex! That’s impossible, unless we are going down a slope, and even if that’s the case. The grounds not moving out from under us, we are rolling down the hill” said the Professor. “Oh yeah, A slope, right.” said Rex embarrassed.

4. “Well at least there are no cracks that we can fall throughhhhhhhhhhh.” Rex said as he fell into a crack in a rock. The Professor looked at Rex with a giant frown on his face, “You had to open your big watery mouth!” “What just happened back there though?” asked Rex. “Capillary action.” the Professor explained. “What?” asked Rex. “Capillary...” the Professor began to say before Rex interrupted rudely. “No, No. I know what you said I was asking what that meant. ” explained Rex. “Ohhh, well. Capillary action is when falls into small openings such as the ones between grains of a rock. Which is the type of crack we are in.” the doctor explained. “Well what do we do now doc? We can’t climb out because the walls are too high. Wow wait what are you doing with that root? He asked Rex quite uncomforted “Well what do we now doc? We can't climb out because the walls are too high. Wow wait what are you doing with that root?” asked Rex quite uncomfortable that the Professor had a giant root in his hand “I'm going to get us out of here!” the Professor yelled as he took the root and fashioned it into a whip. “So what are you doing with this root?” Rex asked again nervously. “Well I saw this movie once and this treasure hunter did this so it’s worth a try, right.” the Professor explained while he whipped the whip back and then launched it forward. Luckily it caught on a stone. ”Okay, what happened next Mr. Movie Star.” asked Rex sarcastically. “Next they pulled themselves out.” the Professor said as he started up the wall. Without saying anything more Rex followed the Professor out of the crack in the rock. When they got out of the crack Rex asked, ”Anyways, what movie did you see that in?” “I think the movie was called Indian Jones and the Raiders of the Lost Ark.” the Professor said proudly that he knew something that saved their lives.” Image from http://downloadlink.org/indiana-jones-and-the-raiders-of-the-lost-ark-1981-dvdrip-axxo-3/

5. Suddenly this tiny lizard runs right across the lake, in front of them! “Wow, Professor that lizard just ran across the water. How did he do that?” Rex asked shocked. “Well Rex, the lizard didn't walk on water he used the water's surface tension to his advantage.” the Professor explained. “What does surface tension mean?” Rex asked. “Surface tension is cause by hydrogen bonds, which is when the hydrogen molecules and the water molecules hold hands to stick together forming water. When hydrogen bonds are created that creates cohesion, which is when water is sticking to water. When this happens there seems to be an “elastic film cover” around drops of water and over puddles, lakes, and ponds. That “elastic film cover” requires energy to break through. That is how the lizard is able to “run” across the lake. The lizard is taking his next steps before his foot has broken through the surface of the water or has broken through the surface tension. So it appears that the lizard is “running” across the water.” the explained the Professor. “Oh! Wow, I really thought that he was actually running on water. You must be the smartest guy in the world, doc!” said Rex. “Well Rex, that is very nice of you Rex but I don't know everything there is to know. That is impossible.” said the Professor honestly.

6. “Wow, look over there that sand is disappearing in that part of the lake how does it do that Professor?” asked Professor. “Well, water is a universal solvent and that means that when anything is put into water and stirred around it disappears and creates a mixture or a solution. It also means that water can dissolve more solutes than any other solvent.” explained the doctor. “OK,” said Rex, “If I push this part of sand into the lake it will mix with the water and become a solution?” “Exactly!” said the Professor. “But I wouldn't step on that because it looks very unstable and you might fall into the lake.” the Professor tried to explain to Rex, but Rex wouldn't listen and he fell into the lake just like the Professor said. The Professor tried to grab him to save him but he wasn't fast enough and fell in himself. “Well at least it is warmer in here than it was outside.” Rex said. “Awww, yes hold on just a second.” the Professor said as he pulled out a thermometer that measured in degrees Celsius. “mmmm, yes .” he mumbled as he took notes. “Wow, you have a pretty smart bunch of kids that Professor.” said Rex. “Yes I do, yes I do.” said the Professor happily. “But why is water's specific heat so important?” asked Rex. “Johnny?” the Professor asked. “Well it says here that because of this slow change in temperature protects marine life and Earth’s climate.” Johnny explained with pride. “I'm proud of you class.” the Professor said with tears of joy in his eyes. Suddenly that happy moment was interrupted by this giant Ice burg flouting its way to the top. “Wow! Hey watch it buddy I'm standing here. The nerve of some ice burgs! What how did he do that? I mean float to the top I can't even do that, but he can! Embarrassing!” said Rex. “Well that I can answer that. Because of water's density (which is how packed the matter in a substance is.) and water's specific heat they allow the ice to float to the top. Preventing the rest of the water from freezing. The ice burg final gets bigger and bigger till it is covering the whole lake in a frozen sheet of ice. This frozen sheet insulates (or keeps warm) the water below it from the harsh temperatures above the ice. Marine and freshwater plants and animals are protected from these harsh temperatures as a result.” the Professor explained. “But there is no full sheet of ice over us yet, doc” said Rex. “In time there will be. Oh look the suns out and it’s just about time for me to go back to class.” said the Professor. “NO! I want you to meet some of my friends. They are up in the clouds. But how will we ever get back up there.” asked Rex sadly.

7. “Wow, you have a pretty smart bunch of kids that Professor.” said Rex. “Yes I do, yes I do.” said the Professor happily. “But why is water's specific heat so important?” asked Rex. “Johnny?” the Professor asked. “Well it says here that because of this slow change in temperature protects marine life and Earth’s climate.” Johnny explained with pride. “I'm proud of you class.” the Professor said with tears of joy in his eyes.

But how will we ever get back up there.” asked Rex sadly. “Well, we are just about done with the Water Cycle we will be up there shortly.” said the Professor. “Yeah but how?” asked Rex again.

Image from http://www.learnforestry.com/lessons/nfw/2009/water_cycle.shtml “Well we were first rained out by the clouds and did our thing here on Earth now it's time to go back up into the clouds by evaporation, and that what will finish the water cycle.” said Professor. As soon as the Professor finished saying that the camera view suddenly moved with a whoosh and appeared above a cloud. “You are amazing doc. Anyways come over here I want you to meet my friends.” said Rex very excited. “Hey guys come over here and meet one of the smartest guys I know.” Rex said boastfully as his walked over to them. “This is Bob, Kristen, Hayden, Campbell, and The Fact guy. Don't let his name fool you his real name is Larry. He thinks that one day Aliens are going to abduct him and ask him many question about the many facts that water has, and if he doesn’t answer them all he will lose his brain forever. So he might think you’re an alien at first it's best just not to say anything and let him tell you as many facts as he wants.” Rex informed the Professor. “Hey doc!” they all said in harmony expect for Larry.

9. “AHHHHHH! Alien! Roughly 70 percent of an humans body is made up of water. When you are born water accounts for approximately 80 percent of a human infant’s body weight. A person can drink about three gallons (48 cups) of water a day. Caffeine can act as a mild diuretic, preventing water from traveling to the place were your body needs. Between 70 and 75 percent of the earth’s surface is covered with water. More fresh water is stored under the ground in aquifers than on the earth’s surface. The same water that existed on the earth millions of years ago is still here today. The total amount of water on the earth is about 326 million cubic miles of water. The United States uses about 346,000 million gallons of fresh water every day. The United States uses nearly 80 percent of its water for irrigation and thermoelectric power.” said Larry. “Will he ever stop?” the Professor asked Rex quietly. “Soon, he is almost done.” Rex answered. “The average person in the United States uses anywhere from 80-100 gallons of water per day. Flushing the toilet actually takes up the largest amount of this water. By the time a person feels thirsty, his or her body has lost over 1 percent of its total water amount. Did I do good? You won't take my brain away will you?” Larry asked nervously staring at the Professor. But he didn't know what to do until Rex nudge him in the back. I AM Made of 70% of water!  70-75% Images from www.internetmonk.com/archive/whats-in-a-name-3 and Microsoft clip art.

10. Finally the Professor said, “You did fine and no I will not take your brain away.” “Phew!” Larry said in relief. “Well Rex it was nice meeting you, bon voyage!” said the Professor as he hug Rex goodbye. “See you later Pal!” as tears came to Rex's eyes. Then the Professor pulled up his sleeve and pushed a shiny red button on his watch. Within seconds he was back in the class room in his regular form, a human. The class cheered and clapped for him, for he was the greatest substitute in the world. “Oh, wow! Look at the time 20 min left. Just enough time for a pop quiz!” said the Professor as the class laughed and complained at the same time.
