Creation of Water: As I Remember Seventh Grade Science Class

Updated on June 1, 2016


In nature, we see the flash of lightning, we hear the thunder and we see the rain start to fall. Some people fear the sound of thunder. Some people make up stories to make themselves feel more secure. There are songs and rhymes. I'm sure you've heard the famous, "it's raining, it's pouring, the old man is snoring. Bumped his head when he went to bed and couldn't get up in the morning."

Some people tell themselves that the heavens is a big bowling alley and God just got himself a strike with the big crash of thunder.

In class, I remember the demonstration and the teacher preparing to physically show us how water is created. He may have even spit into the bottle.

He showed us the bottle and the elements that he forced into the bottle. He had two tanks by the bottle he was filling. The each tank was filled with its own element. One contained hydrogen and the other oxygen.

The year was 1974.

If you look it up, you read that regular hydrogen heavier than oxygen. Oxygen from a tank, is heavier than the photosynthesized oxygen we breathe from the plants that make it? Factually, it is a tenth heavier. Hydrogen is lighter than oxygen. But, water is heavier when the reaction takes place. So, you have the hydrogen sitting on top of the oxygen and then, as pressure is put to it and there is a slight spark, those two elements explode and make water. The water drops to the bottom since it is heavier than everything else in the bottom and there is gravity which pulls it downwards.

In nature, Oxygen is made by green plants. The chlorophyll in the leaves changes the carbon dioxide that we breathe out to the oxygen that we breathe in. There is oxygen being made by plants in the air and there is oxygen being made by plants in the water.

He was a good teacher. He looked at each student as they arrived that day. I think, as I remember, that he was probably noting which students showed some curiosity about the bottle that was sitting on the table.

It wasn't just the bottle, mind you. It was also the two tanks near by, and the rubber tubes, and the sparker. I recall that he had the valves adjusted for the amount that was coming out of the tanks.

For water, the chemical symbol is H2O. There is a reason they call it that. It's because the H stands for Hydrogen. The O stands for Oxygen. You need two parts of Hydrogen to one part of oxygen. Then, as they mix together in that proportion, there needs to be a certain amount of pressure and then, a small amount of fire - or a spark. The two elements when mixed together in this fashion, and ignited, blow up and cause water.

Simple as that.

The Bottle

The large bottle with small mouth. It has just occurred to me why this bottle that we keep coins in jars my memory sometimes. It's the same type of bottle. Heavy. Thick. I just walked over and felt the glass. It's at least a quarter inch thick, if not three-eighths thick.

My son pointed out that people make wine in those jugs. I don't know what it was originally used for, but it's the same type of bottle that was used for the demonstration.

Water is Old

Water has been around since the beginning of time. According to the Bible, we started with a pocket of water and the elements have been recreating it ever since.

Water Machine

In theory, you should be able to build a crankshaft, that moves a cam up and down in a cylinder. Similar to a car engine, but different.

You'd have to have three inlet valves to let in hydrogen and oxygen. You'd have to have a cam to create a lot of pressure. When the cam has the hydrogen and oxygen compressed, then it would have to be ignited. This explosion causes water and the valve at the bottom would open up and let the water drain out into a waiting reserve to be dispersed into a bottle, perhaps?

In Nature

I am not going to quote Wikopedia about the cycle of water. You can go there and read up on it by yourself.

It's raining today. It's been raining for hours. Everything is wet. I'm fairly certain that there was some lightning while I slept last night. The barometric pressure at the moment is 29. The temperature outside is 65 degrees.

It wasn't raining earlier when I walked outside. The grass was actually wet with condensation, so the temperature must have been a little cooler. I know that my tennis shoes are still soaked from walking in the grass.

Ever seen a glass mug when you take it out of the freezer and the warm air in your room hits it. It gets frost on it, and eventually will melt and leave a small puddle.

It's Raining Today

There has been enough rain to fill the wheelbarrow with water. There are droplets of water running down my glass door. So much that you can only see a distorted view of my wooden deck outside.

The timing of this is perfect. I needed water to fill up my strawberry stump and this suits me perfectly! I was going to paint today in my stairwell, but, it's too humid. Well. humid right now. Perhaps that's just an excuse. I intend to paint. I have the paint. I have to go to graduations today. Ah, yes. My list of excuses is never ending, but it will get done in the next day or two.

      Hi Char

      Sounds like you had a great teacher who was able to practically demonstrate an interesting process.

      Thanks for sharing
