Homework
Homework: Bring 3 ideas about how you think chemistry will be used in the future. Use complete sentences and future tense. (ask a parent or family member for ideas)
Week 7 In-Class Activity
- Part I
- In your science notebook, write the title: Future of Chemistry
- Click on the button below. Pick four (4) principles you think are the most important and in your owns words explain each principle in your notebook. (If you click on the blue title, you will have more information to help you)
2. Open Amazing Atom. You will find names of lots of countries and 3 main links about water supply, global health and world nutrition. Click on each of the “I” and read the information on why it is importance of atoms regarding each aspect. Take notes
3. Choose 1 country and take notes regarding each aspect cited above
4. As you are reading this information, think about ways to connect it with 1 or 2 of the 12 principles of green chemistry. Take notes, make sure they are clear. You can use a chart, or a table, but be clear.
5. Watch this image about Space and Chem elements. Read the information on the left of the graph. Notice that there are some elements taken into account in the graph.
What this meand is that...Asteroids are the most valuable real estate in the Solar System.
Why go to space to mine asteroids? Simple, many of Earth’s precious resources we depend on today originally came from asteroids. Isn’t it about time we went to the source?
Every new frontier that has ever flourished in the history of humanity did so by utilizing the local resources at hand. Space will be no different.
The asteroids we are targeting contain valuable materials such as iron, nickel, rare platinum group metals, and hydrogen and oxygen for rocket fuels. They are energetically much closer to Earth orbit than both the surface of Earth and the Moon. There is no better “local” source of resources to cultivate this frontier. (taken from http://www.planetaryresources.com/#home-asteroids)
Week 8- End of Term Project Instructions
You will research 3 elements. Start working and do a little each week. Organize your time during the next few weeks. You will have time in class to research, but if you know you need more time, make sure to dedicate some time at home. OR make sure to use your time in class wisely.
You will upload the document to your weebly page, so make sure you know where saved (USB, gmail, etc...)

Title: The future of chemistry
Where is chemistry going to and where on Earth (literally) are they going to fins new elements, or even those that we currently need since they are saying that they are all ending!
Watch the following video and answer the questions below: - Video No. 1 : easy water purification secret
http://www.universetoday.com/101552/earth-is-the-most-exotic-place-in-the-universe/
- What material is needed for this process of purification?
- Why is the sun important for this process?
- In which situations would you do this type of purification?
- What is WHO?
Read these texts and watch the video. Answer the question below
Proteins are organic compounds that contain the element nitrogen as well as carbon, hydrogen, and oxygen. Proteins are the most diverse group of biologically important substances and are often considered to be the central compound necessary for life. In fact, the translation from the Greek root word means “first place.” Skin and muscles are composed of proteins; antibodies and enzymes are proteins; some hormones are proteins; and some proteins are involved with digestion, respiration, reproduction, and even normal vision, just to mention a few.
Taken from: http://www.infoplease.com/cig/biology/proteins.html
Lipids are organic compounds that contain the same elements as carbohydrates: carbon, hydrogen, and oxygen. However, the hydrogen-to-oxygen ratio is always greater than 2:1. More important for biological systems, the carbon-to-hydrogen bonds are nonpolar covalent, which means that lipids are fat soluble and will not dissolve in water.
Taken from: http://www.infoplease.com/cig/biology/lipids.html
Carbohydrates consist of the elements carbon (C), hydrogen (H) and oxygen (O) with a ratio of hydrogen twice that of carbon and oxygen. Carbohydrates include sugars, starches, cellulose and many other compounds found in living organisms. In their basic form, carbohydrates are simple sugars or monosaccharides. These simple sugars can combine with each other to form more complex carbohydrates. The combination of two simple sugars is adisaccharide. Carbohydrates consisting of two to ten simple sugars are called oligosaccharides, and those with a larger number are called polysaccharides.

Read the following text and answer the question below:
Contributions made by chemistry
The contributions of chemistry to society are vast and almost numberless. An in-exhaustive list would include
An understanding of chemistry was also key to the development of modern food health and hygiene practices. By understanding the actions of microbes on the human body, these practices have helped eliminate other dread diseases in the Western world, such as dysentery and cholera, as well as many types of food poisoning.
Similarly, to Jenner's vaccines, understanding the chemistry of modern diseases is the key to the ongoing battle against conditions like cancer, AIDS and the common cold. By understanding the chemistry of how, say, cancer cells do what they do inside a human body, we have been able to devise treatments that can in some cases kill the disease, or at least provide an effective treatment regime. Diagnostic tools like dyes,that show up only certain times of tissue on ultrasound readers are also the result of chemical marking processes.
Chemistry was at the heart of understanding, that a chemical sludge pumped from underground had combustible properties that could drive an engine - so without an appreciation of chemistry, your car wouldn't start. Ironically, chemistry is also now at the forefront, of the search for alternative ways to drive car engines without leaving the ecologically harmful residues that current engines do.
From oil comes plastics - but only if you understand how to make them, which means, altering the chemical structure of the oil and processing it to synthesize the plastic out of which half of our modern world appears to be made. Likewise, synthetic fibers are called synthetic because they've been developed by chemists to behave in certain ways - without chemistry, there would be no lycra.
Also, in the modern age, as we have become more fastidious about cleanliness and our appearance, we have developed huge industries dedicated to the development of cosmetics and cleansers - all of which are mixtures of chemicals (either naturally or synthetically produced), that have been blended to give us the effects we want without causing us any harm. Likewise, our quest for cleanliness has led us to develop surface cleaners, which are mixtures of entirely different chemicals that will destroy bacteria - and again, our knowledge of chemistry has both advised us of the threat, and helped us master it.
This list is by no means complete - chemistry has had a part in practically every facet of the modern world - but without chemistry, it should be clear that the world we live in, would look very different.
- Which of the contributions named in the text do you consider are the most important? Explain your answer.
