1 1)Objective: I will learn about non- metals and their use in everyday life. 2) Essential Question: Can you explain the importance of non-metals in everyday life? 3) Warm-up: Create a circle web of the different categories of metals on the Periodic Table. 4) Vocabulary: halogen, noble gases, metalloids, law of conservation

2 1) Halogen= reactive elements found in group 17 of the periodic table. Halogen means “salt-forming.” 2) Noble gases= non- reactive Elements found in group 18 of the Periodic table, often used in glowing electric lights. 3) Metalloids= elements with properties of both metals and non-metals, found along the zigzag line of the Periodic table. (example: silicon) 4) Law of conservation= States that the combined mass of the substances in a reaction will be equal to the mass of the resulting substance in that reaction. (5 grams of X + 10 grams of Y= 15 grams XY)

7 Co ngratulations! You are about to have the grand opening for your first business. You have decided to open up a store of metals. It’s time to get to work so you can load the store full of customers for the grand opening. Think of the types of metals you will sell and what they might be useful for. You may refer to the list of metal objects you found in the scavenger hunt yesterday.

8 Steps for creating the store of metals 1) Identify 5 metals your store will sell. 2) Draw illustrations depicting what the metals you sell may be used for. 3) Come up with a name for your store of metals. Create a propaganda slogan to market your store to the public 4) Prepare a commercial to present to the class advertising your store.

9 1)Objective: I will learn how to tell the difference between a chemical change and a physical change. 2) Essential Question: How would I identify the difference between a chemical change and a physical change 3) Warm-up:. What property of aluminum allows for it to be rolled into thin sheets to make aluminum foil? 4) Vocabulary: chemical change, physical change, precipitate, endothermic reaction

10 1) Chemical change= a change in which substances combine or break apart to form new substances. (example: the rotting of a banana) 2) Physical change= a change in the form of a substance. (example: water turning into ice) 3) Precipitate= a solid that forms from a solution during a chemical reaction (often formed from the reaction of two clear liquids) 4) Endothermic reaction= a reaction that absorbs energy in the form of heat. (example: cooking an egg.)

11 Lab Zone Discover p. 628

12 1) In what state are most non-metals found at room temperature? 2) What properties of oxygen make it a non-metal? 3) Why do the non-metals in group 18 rarely react with other elements to form compounds? 4) What property do elements in mixed groups share? 5) Why are most nonmetals found as part of a compound

13 1) Most are gases, some are solids, only one is a liquid 2) It is a gas at room temperature and a poor conductor of electricity and heat 3) They do not readily lose or share electrons 4) They all gain, lose, or share the same number of electrons. 5) Non-metals are very reactive.

14 6) What causes the difference between the reactivity of halogens and noble gases? 7) What are some properties of metalloids? 8) What is the most useful property of metalloids? 9) What is a semiconductor? 10)What are semiconductors used for?

15 6) halogens easily gain or share one electron when reacting with other elements. Noble gases do not usually gain, lose, or share any electrons. 7) They are solids at room temperature. They are brittle, hard, and somewhat reactive. 8) Their varying ability to conduct electricity 9) A substance that conducts electricity under certain conditions 10) Computer chips, transmitters, lasers

16 Teacher Demo: Hydrogen Peroxide vs. Water

17 Paired Reading: Read p Take notes as you read.

18 Complete the LabZone Skills Activity on p. 652

19 Discussion of Teacher Demo

20 Write two paragraphs identifying the difference between chemical changes and physical changes. Give specific examples of each.

21 Codes:10277, 10278

22 1)Objective: I will learn how chemical reactions are described. 2) Essential Question: How would I describe and evaluate the different types of chemical reactions? 3) Warm-up: Math Analyzing Data questions p ) Vocabulary: exothermic reaction, synthesis, decomposition, replacement

23 1)Exothermic reaction= A reaction that releases energy in the form of heat. (Example: The expansion and movement of gases out of the engine of a vehicle.) 1) synthesis= the reactions of two or more elements to make complex substances. (Example: Hydrogen and oxygen combine to make water) 2) decomposition= the breaking down of compounds into simpler products (Example: Hydrogen Peroxide becomes water) 3) replacement= when elements trade places with one another, or when one element replaces another in a chemical reaction (Example:When heating copper oxide, carbon takes the place of copper)

27 Read p Take heading notes in your notebook as you read.

28 Create a quiz of ten questions from what you have read in p

29 1)Objective: I will apply the concepts I have learned this week through by using my inferencing skills to decipher context clues. 2) Essential Question: How well do I understand the vocabulary words I learned in class this week? 3) Warm-up: 5 minutes of study time for your vocabulary quiz 4) Vocabulary review: endothermic reaction, exothermic reaction

30 Tips for Success on Today’s Vocabulary Quiz 1) Think of each statement in the way it would be said by someone. 2) Think of the hints (underlined words) in the statement that give away the vocabulary word. 3) Read all of each statement first and match the statement with the word that best fits. 4) I believe in you. I know you will do well. Believe in yourself also and you will be amazed.

42 1) Radioactive dating= the process of measuring the amount of radioactivity over time in an atom in order to determine a rock’s age 2) Half-life= the length of time it takes for half of the atoms in a sample of a radioactive element to change from one unstable form to another form

43 1) Read p. A53 to A59. Take Cornell Notes on what you read

44 Complete the Date a Fossil Activity worksheet

45 Read p. A58 about the radioactive breakdown and dating of rock layers

46 1)Objective: I will take a vocabulary quiz on the words learned for the past two weeks. 2) Essential Question: Can you explain the different methods science use in dating materials such as rocks, trees, ice, etc. 3) Warm-up: Read p.
