Instructions: Write two separate paragraphs (at least 6 sentences each – this does not mean you simply stop writing at 6 sentences) on two different examples of chemistry in everyday life. If you Google “Chemistry in Everyday Life” you will get lots of ideas to choose from or come up with your own. You may not use the topics discussed in your textbook.
Describe the example in your own words (do not copy it from the Internet). Include your thoughts, experiences, opinions on the subject and anything you would like to add. As well, discuss the actual chemicals involved – do a little research on what is happening, the processes, etc. For example, if you pick digestion, you would talk about the types of enzymes at work in your body, what happens to the nutrients, the acid in your stomach, etc. (You cannot use that one).
You will be graded on spelling/grammar so I would recommend having a fellow student or friend look it over before submitting it. Paragraphs should be double spaced, 12 point font and margins are to be 1 inch all the way around. Anything you read, look up on the Internet, etc. must be cited.
Talking about the fact that chemistry is in our lives and how it affects us in general is not a topic, nor does it “count” for your 5 sentences. Do a little research. I want you to LEARN something with this assignment.
You may not pick ice floating on water, hand/dishwashing/laundry soap or detergent, why onions make your eyes water, or why water boils. Be creative. Really THINK about the chemicals/chemistry going on around you everyday.
Put each paragraph on its own page. Your name should be up in the right hand corner.
Good example paragraph:
I have a saltwater aquarium and it requires a significant amount of work to keep the salt content, nutrients and dangerous molecules in the right balance. If the salt content is too high or too low it will cause the fish to suffer. These hypertonic and hypotonic solutions will result in the fish’s cells shrinking or swelling causing death. Other nutrients are important for fish and reef survival such as certain metal ions like calcium. Fish waste products include ammonia, nitrate and phosphate. These polyatomic ions are not dangerous in low concentrations however at high concentrations they will interfere with fish survival. To ensure proper survival of all the organisms in the tank, frequent water changes are performed to dilute out some of the harmful molecules. Unfortunately, the good molecules get diluted out as well so the keeper must be certain to supplement the tank to the appropriate levels. This example of chemistry in everyday life is easily performed by anyone willing to put in the effort to learn the hobby and does not require a chemist for an ultimate tank experience.
Very bad example paragraph:
Have you ever wondered why ice floats? It floats because it is lighter than liquid water. It’s a good thing too, because if ice was heavier than water it would sink to the bottom of lakes and oceans and kill the animals because they would freeze in it. Other things are heavier than ice, that is why they do not float. It all has to do with the density of water and of ice.
