Pitfalls to Learning
Learn the pitfalls you encounter when learning a difficult subject like chemistry.

Pitfalls of Learning Chemistry Tutorial (2/1)

NEW >> How to Create a Sapling Learning Account (2/3)

Chemistry in a New Light
Your instructor has created a way to tie all areas of chemistry together and at the same time make it easier to comprehend. All chemistry topics are a mixture of building blocks, force/energy, and math.

Scientific Skepticism:
The next two tutorials develop your skills at scientific skepticism and help you understand why societies make poor choices.

PROBLEM WITH AUDIENCES

Audiences come to enjoy a performance. Their frame of mind is to be entertained. Not much interest is given to what happened in preparation of the performance or what happens after the performance. This makes them uninformed to the full depth of what the performance really should mean to them. As citizens and consumers we often have the same shallow insight as audiences. We are focused just on the product, results, performance, or solution. This makes us rather gullible and vulnerable.

CHEMISTRY AND SOCIETY IN THE NEWS (This webpage is used for various assignments)
Our Society had three problems which we solved using chemistry; however, in doing so, we created new problems with negative consequences.
Society Problem #1: We want a multitude of products that are cheap and readily available.
Society's Solution: Mass Production with global distribution of products.
Positive consequences: We are all materially very wealthy. Owning many more things than our ancestors ever dreamed of. Because of mass production of food products, we also have access to more food than our ancestors ever dreamed of.

Society Problem #2: Find raw materials that allow easier and faster production of manufactured goods. (This problem is related to problem 1) This material should be cheap, lightweight, waterproof, inert, and moldable.
Society's Solution: Polymers: Chaining together simple molecules allows the creation of a variety of materials known as polymers or plastics. These simple molecules primarily come from petroleum.
Positive impact on society: Plastics contribute to our material wealth because they are cheaper to manufacture. Cars are lighter in weight and therefore produce less pollution. Our clothes are warmer, last longer, and are easier to care for. Things are cheap enough to be disposed of; eliminating cleaning and use of water and soap. Plastics are waterproof and are durable in all weather conditions. Plastic containers or bags take up less space at home or in the landfill. Some plastics can replace body parts.
Negative consequences: • Because of plastics' durability, they do not decompose easily in landfills or as litter. • Some plastic holders for beverage bottles have strangled marine animals. • Plastics are made from petroleum which is a limited resource.
Tutorial #H1: What are Polymers? How are they used? The consequences of using polymers. (4/15) (Reading assignments from textbook will be added to supplement the below tutorials) Quiz on Polymers is here. Send answers via email. Score will be recorded in Sapling Learning(4/18) Exercise H2 (extra credit): Visit http://H2No.org/PlasticCodes.asp and Find plastic items around the house that has these codes and report what polymer code is printed on them. Give at least three (If above link doesn't work, do a Google search for "plastic codes".) Send answers via email. (12/1)

Society Problem #3: For refrigeration, we need a gas that upon compression will turn to liquid at room temperatures. It also cannot be flammable and should be cheap to make.
Society's Solution: Combine a few chlorine atoms, fluorine atoms, and carbon atoms to make a variety of compounds called chlorofluorocarbons.
Positive Impact on Society: The comfort of refrigeration was enjoyed in homes, cars, businesses, and elsewhere. This gas was also used to make refrigerators and freezers. Chlorofluorocarbons were useful in spray cans, the making of Styrofoam and other foam-like plastics, fire extinguishers, cleaning solvents, and other products. It had a huge positive impact on society, which is why accepting its negative consequences was difficult.
Negative consequence: The chlorofluorocarbons worked their way into the upper stratosphere and destroyed ozone, which blocks the sun's high energy ultraviolet light. Excess ultraviolet light damages skin, breaks DNA, causes skin cancer, damages eyes, kills plants, and causes many more problems. Life on Earth will cease to exist if too much UV light gets through the atmosphere. A hole in the ozone layer around the south pole has grown to 10 million square miles (twice the size of United Sates). People in Antarctica and southern tip of South America are now warned to wear thicker clothing for protection. The ozone level over the whole Earth has also dropped.

This makes them uninformed to the full depth of what the performance really should mean to them. As citizens and consumers we often have the same shallow insight as audiences. We are focused just on the product, results, performance, or solution. This makes us rather gullible and vulnerable. A1: Read tutorial about the Problem with Audiences. (2/12)
WHAT HAPPENS BEHIND THE SCENES To gain the ability to see through tricks and to totally evaluate what is being presented, we need to step behind the scenes. This is true whether it's a card trick, a chemistry trick, or anything in between. A2: Read tutorial about What Happens Behind the Scenes. (2/15) Quiz on both "Problem with Audiences" and "What Happens Behind the Scenes" at Sapling Learning (2/18)
VIDEOS REAL OR FAKE? In this exercise you will try to determine if the 9 videos listed are fake or not. These are listed in Sapling Learning. First try to search the web or see if you find information on whether if they are fake or real. If you can't find out, then use your judgement to explain why you think the videos are real or fake. I'm more interested in what our observations or reasoning behind your decision rather than being accurate if it is real or not. In other words, this is practice on using critical thinking and scientific skepticism. (2/21)
