2 Vocabulary I should know: #2 1. Matter has mass and takes up space 2. Energy The ability to do work ; power that is gotten from some other process 3. Open System Matter and energy freely move in and out 4. Closed System Energy can move freely in and out of the system but matter cannot 5. Isolated System Neither matter or energy and can move in or out of system (these don t exist) 6. Element a substance that cannot be broken down into a simpler substance 7. Compound made of two or more elements chemically bonded together 8. Mixture made of two of more elements NOT chemically bonded together 9. Earths Internal Energy Earths energy that is found on the inside of the earth, of which there are two. 1. Radioactive material and 2. Heat leftover from earths formation (which was made by gravity) 10. Earth s External energy Earths energy that comes from outside the earth, which is the sun (fusion) 11. Water Cycle process by which water endlessly circulates through earths sphere 12. Carbon Cycle the process by which Carbon endlessly circulates through earths sphere 13. Biosphere all living things on earth 14. Atmosphere the mixture of gasses that surround our planet 15. Geosphere all of the solid rock on earth, from the surface down to the core 16. Hydrosphere all of the water on earth 17. Fossil Fuels coal, oil, and natural gas, formed from the remains of past living things 18. Decomposers an organism, like a mushroom or bacteria, that eats dead things. (They also return CO2 to the atmosphere and nitrogen to the soil) 19. Conservation of matter matter cannot be created or destroyed, it only changes form. (nuclear explosions are an exception) 20. Conservation of energy energy cannot be created or destroyed, it only changes form. (nuclear explosions are an exception)
3 #3 Energy in the Earth System LT 1.1: I can explain the difference between matter and energy and understand their role in earth systems.

5 Basics of Chemistry LT 1.1: I can explain the difference between matter and energy and understand their role in earth systems. Key chemistry words: atom, element, molecule, compound, mixture, physical change, chemical change. #5 1. A substance that cannot be broken down into a simpler substance =. 2. Simplest unit of matter is (not counting protons, quarks, bosons, etc.). 3. Two or more different elements bonded together make a. 4. Two or more different atoms bonded together. 5. Two or more elements not bonded together makes a. 6. Two or more compounds not bonded together make a. 7. Two or more elements and compounds not bonded together makes a. 8. A change that doesn t make a new substance. 9. A change that does make a new substance. 10. How are the words atom and element similar? How are they different? 11. How are the words molecule and compound similar? How are they different? 12. How are the words physical change and chemical change similar? How are they different? 13. What is the main difference between a compound and a mixture?
6 The spheres represent elements. The little sticks represent bonds between the elements. In order for compounds to be formed, all of the holes in the ball should be filled with bonds. Some Rules: #6 Every bonding place should be filled (and not just with a stick) Springs (double bonds) can be used if there are extra holes to be filled Most things don t like to bond with themselves if there is something else to bond with. Oxygen likes to get away from other oxygens if it can. Rings are really rare for most things (except carbon, they like 5 or 6 carbons in a ring) Carbon likes to bond with other carbons to make chains. Yellow: hydrogen (H) Red: Oxygen (O) Purple: Sodium (Na) Green: Chlorine (Cl) 1. Take a yellow ball. a. What substance is it? b. Is it an element, compound, or mixture? c. Take a yellow, red, purple, and green ball and hold it in your hand. Are you holding a compound, mixture, or element? 2. Make water (H 2O). Draw a picture of it. a. Is it an element, compound, or mixture? 3. Make salt (NaCl). Draw a picture of it. a. Is salt an element, compound, or mixture? 4. Make oxygen (O 2). Draw a picture of it. a. Is it an element, compound, or mixture? 5. Make a mixture of salt and water. Draw it. 6. Separate the mixture. Is this a chemical or physical change? 7. You can split water with electricity to make hydrogen (H 2) and oxygen (O 2). Take two water molecules and split them to make H 2 and O Was this a chemical change or a physical change? Why?
7 LT 1.1: I can explain the difference between matter and energy and understand their role in earth systems. 1. What color is carbon in the molecular models? 2. How many bonds does it need to make? Important Carbon Molecules #7 3. First off, carbon can exist by itself in nature. Can you think of an example of pure carbon that is commonly used? (hint: it s in your pencil) 4. Make and draw models of the following carbon molecules. They are all important in what we will be talking about the entire year. a. Methane (CH 4) b. Ethyl alcohol (C 2H 6O) c. Carbon Dioxide (CO 2) d. Glucose (C 6H 12O 6) 5. Which of the above molecules is a type of human food? 6. Which of the above molecules is a type of human waste? 7. Which are gases at room temperature? 8. Which are liquids at room temperature? 9. Which are solids at room temperature? 10. Which of the above are compounds? 11. Which of these do humans eat as food and which do we give off when we breath? 12. In the previous question, is this the same carbon or different carbon? 13. How can the carbon that is in the glucose in your GatorAde get into the air?
8 Important Nitrogen Molecules #8 1. What color is the nitrogen in the model kit? 2. How many bonds can it make? 3. Nitrogen can bond with itself to make N 2. Make it and draw it. This is the gas that is in the atmosphere. 4. Make and draw Nitrogen dioxide (NO 2). 5. Make and draw an Ammonia molecule (NH 3). 6. Both of the above are fertilizers. Plants need the nitrogen to make proteins. If you can make the model of the simplest protein, I will give your group a sticker. The formula is H 2NCHRCOOH. Draw it. 7. Nitrogen is also a main element in one of your wastes. Guess what waste it is. 8. Can other living things use your waste? Explain why or why not.
