What you Breathe

Have you ever wondered about what you breathe? Sure, you know you breathe mainly oxygen, but how much do you really know about what you’re inhaling at this very moment? Now you can finally know!

Oxygen is a chemical element with the atomic number of eight. The symbol of oxygen is “O.” Humans breathe in oxygen in a process called cellular respiration, and plants use oxygen in a process called photosynthesis.  Oxygen is all around us, but we can’t see it.  It’s a bodiless gas that makes up 21% of the Earth’s atmosphere.  Oxygen was discovered in 1774 and comes from the Greek word ‘oxy genes’, meaning acid forming.

Oxygen is a precious resource because most organisms need to breathe it to survive. Oxygen is also used in cellular respiration, which is a vital process in organisms. As you may know, cellular respiration is the process in a cell that turns water and glucose into  carbon, water, and energy that the cell can use to work and live. Even high up in the Earth’s atmosphere, oxygen is present, along with another necessary element, carbon. Oxygen is one of the most important elements to sustain life, without it our health would suffer severely and we would possibly die. Oxygen is also very important because it helps destroy the harmful bacterias but doesn’t harm the good ones or the ones that we need.

The role of oxygen in photosynthesis is that oxygen is the product of photosynthesis. During the process of photosynthesis, plants take in carbon dioxide and H2O to provide food for themselves in order to grow, and emit oxygen which humans and many other organisms need to survive. Oxygen is very important in cellular respiration, because it helps generate energy. During cellular respiration in a plant, glucose and carbon dioxide are used to make food for the plant, the oxygen supplying the plant with energy to do so.

Astronauts on the ISS(International Space Station) get their oxygen from water.  This process is called electrolysis, which uses electric energy from solar panels, which they use to split the water into hydrogen and oxygen gas.

Oxygen is everywhere and we wouldn’t be here without it.  Do we really want to throw it all away by adding air pollution to the Earth? Think about this, you are slowly killing yourself by not trying to save the Earth.  Would you rather die or would you rather take simple steps in your everyday life to save the Earth?


Our project is all about being green, while still be a little formal. Our flower garden has bright flowers, such as Firecracker Ferns, & Eastern Purple flower. We have soft green Monkey Grass for ground cover. Our vegetable garden has plants like Looseleaf Lettuce & Cherry Tomatoes.

We want our garden to be a place where teachers want to hang out, a place that’s peaceful and relaxing. We will have spiders (non poisonous), Lacewings, Ladybugs, and Ground Beetles as our helpful bugs. We will have a contained Eastern Black Swallowtail for food for our helpful bugs, creating an ecosystem, because the caterpillars will eat, and will be eaten by the other bugs, which will eventually go back into the soil, making the soil rich.

We have a Wood and Wire compost bin, which will produce compost fast and well. It is one of the nicer looking bins, so it fits with our theme ( Green Formal). We have stone paths, and wooden benches so the teachers can sit and walk off of the grass.

We hope you like our ideas for the garden, and we’re still planning! If you have any ideas, please comment!



  1. Great job on this blog. It is important to be informed about this kind of stuff, just to see how much you really know about your environment.

    I like how you guys described what you are planting in the garden, and also whatelse we breathe in the air.

    This blog posts vaguely describes everything the 7th grade science class is learning right now. It is important to know what is going on in your environment, because whether we know or not, our environment is changing constantly so we must be prepared to know how it can effect us in a positive or negative way.

    I love oxygen, and i think we all should love it. Without it we would die, so i like that ya’ll did a blog on it. We really don’t see the importance of it. Thank you for the helpful information.

  5. Great connections between what we are learning inside the classroom to this project. You gave a pure and detailed description of what oxygen is. You left with a strong message at the end. You conveyed a good message about how important oxygen is. This blog at first seemed factual, but got more personal along the way. What are you doing to decrease the size of your carbon footprint?

    I never really thought about what I breathe, your design sounds very eco-friendly

    I like how you include your plan for your garden. This post has a pretty important message. It also makes oxygen even more important than it already is.
