Elements, Compounds, Mixtures.

1. Elements, Compounds, Mixtures. Ms Bologna

2. Monday: Chickasaw Challenge 1. Brainstorm, what do you think that the difference between a compound and a mixture is? 2. Create a word web for compounds. 3. Set a goal for yourself this week

3. Assessment Reflection! • 1. Answer the assessment reflection questions: • What was your initial reaction to your score? • What did you do to get this score? • What actions are you going to take next time to improve this score? • What is all the numbers that you got wrong. • Use your graphs to track your data

4. Class Pledge • We Will… • Work Hard NOT because we have to but because we WANT to for our own success and future. • We Can… • Achieve excellence through hard work and motivation • We All… • Work together to reach our greatest potential • Our Future… • Is college bound!!!

5. Daily Objective SWBAT differentiate between elements and molecules. SPI 0807.9.3 Classify common substances as elements or compounds based on their symbols or formulas.

6. Rapid Review • Find Your Match!!!.. You will each get a word or a definition you will have 5 minutes to find your MATCH. • Expectations: • You have to walk only. • Must only be at a whisper • Spread your self around the room. • Sit with partner when you think you have found your match. • The room should have a BUZZ!! No louder • Best class will get 3 links on Tuesday.

8. Compounds • 1. Two or more differentelements arechemically joined

9. Compounds • 2. When they are chemically combined, new chemical bonds form between them.

10. Compounds • The characteristics (properties) of a compound are different than the characteristics (properties) of their component parts (of the elements that make them up)

11. Compounds • Compounds have a definiteratio. If I change the ratio, I completely change the properties of a compound. • CO2-Carbon Dioxide CO-Carbon monoxide

12. What Ways Might I have to Identify Compounds • Di= 2 • Mo=1 • Carbohydrate • Carbon dioxide • Sodium fluoride • Carbon monoxide Symbols??

13. Molecules Molecules are different than compounds. They are composed of 2 elements but they are the SAME element. Ex 02, C5,

14. Give one, Get One You have 20 Blanks on your board. You can use your book or notes. Using 8 of those squares I want you to provide 4 examples of molecules and 4 examples of compounds. Leave the rest of the space blank. Travel around the room and give and get examples of elements and compounds from your classmates.

15. Create an Interview or Movie Skit. • Create an interview or a Movie skit that explains to your audience the difference between elements, compounds, and molecules. • Groups of 3 • Must write down the script • 10 minutes total to complete and practice. • Must provide an example of each. • Record some people at the end.

16. Tuesday: Chickasaw Challenge • 15. Which of the following materials is composed of only one kind of atom? • A. Water • B. Helium • C. Air • D. Sugar • 2. Which of the following represents a compound? • A. H2 • B. NH3 • C. O3 • D. N2 • Answer each of the questions and explain why each answer choice (a,b,c,d) is correct or false. • 1. Out of all the families which are the most reactive? • Noble Gasses • Transition • Alkai earth • Alkali Metals.

17. Class Pledge • We Will… • Work Hard NOT because we have to but because we WANT to for our own success and future. • We Can… • Achieve excellence through hard work and motivation • We All… • Work together to reach our greatest potential • Our Future… • Is college bound!!!

21. What are some differences between

22. Mixtures • Two or more substancesare physically combined • The substances in a mixture retain (keep) the properties that they originally had

23. Mixtures • Physical properties can change, but there isnonew substance that is formed • No new chemical bonds are formed • Can beeasilyseparated into distinct parts

24. Examples of Mixtures • Salt water • Trail mix • Granite • Sand • Soil • Concrete • Salad dressing • Koolaid

25. Magic Rule Step 1: Ask Yourself: Can you do it yourself? Step 2: Was it formed by a chemical change? Step 3: Could I get the original parts back?

26. Compound or Mixture? • Guided Practice. Grab a card… and stand by the section of the ROOM silently if your card is an example of a mixture, element, or compound.

27. JuryDuty You decide!! Element, Mixture, or Compound

28. Rules • You must decide if the following are elements, compounds, or mixtures • Ms. Bologna is the judge and you are all the defendants. • Your lead attorney (speaker) will rotate every case! • This means that you must provide explanation and defense for your choice!—there may be one right answer?! • You will have 3 minutes to discuss among your jury and 30 seconds to defend your case! • Be prepared to be called on at any time!

29. Example Case • Good defense: • Acid rain is a compound because the rain is a new substance with new properties. This is evident by the fact that the acid rain is acid, but the sulfur dioxide and water that chemically combine to make it up are not. When acid rain is created, chemical bonds are created. Acid rain: which is formed from sulfur dioxide and water Bad defense: Compound that has been chemically combined

30. Case #1 • Our atmosphere is made up of mainly nitrogen (N2) and oxygen (O2) gases

31. Case #2 • Rust

32. Case #3 • The water in this swimming pool

33. Case #4 • Stainless steel: contains iron, carbon, chromium, and nickel. Carbon gives it its hardness. Chromium and nickel it give a silvery look.

34. Exit Ticker Cold Call Which of the Following is a Mixture. 2. Give one example of a mixture. Justify why it is a Mixture NOT a compound.

35. Wednesday: Chickasaw Challenge 1. Create a Tri-Venn Diagram comparing Elements, compounds, and mixtures. Be sure to provide examples of each

36. Class Pledge • We Will… • Work Hard NOT because we have to but because we WANT to for our own success and future. • We Can… • Achieve excellence through hard work and motivation • We All… • Work together to reach our greatest potential • Our Future… • Is college bound!!!

37. Daily Objective SWBAT differentiate between compounds and mixtures. SPI 0807.9.3 Classify common substances as elements or compounds based on their symbols or formulas.

38. Rapid Review Write an example of an element on one sticky note, compound on the next, mixture on the third. Check your examples with a partner and make sure they are correct. Place on the correct posters!

39. Types of Mixtures • Heterogeneous Homogeneous

40. Two Types of Mixtures • Heterogeneous Mixture • A mixture that does not appear the same throughout • Hetero=different • Examples: • Granite • Chex mix • Oil and water • Homogenous Mixture • A mixture that appears the same (uniform) throughout • Homo=same • Examples: • Salt water • Koolaid

41. Three Types of Homogenous Mixtures • Solution • Suspension • Colloid

42. Solutions • A solution is a mixture that appears to be a single substance.

43. Solutions In a solution, the solute is the substance that is dissolved. The solvent is the substance in which the solute is dissolved.

44. Examples of Solutions • Liquid solutions: soft drinks, gasoline, and tap water.

45. Homo

46. Suspensions • A suspension is a mixture in which particles of a material are dispersed throughout a liquid or a gas but are large enough that they settle out.

47. Colloids http://www.brainpop.com/science/matterandchemistry/compoundsandmixtures/preview.weml Brainpop Quiz!!

48. Compound or Mixture? • Peanut butter and jelly sandwich

49. Compound or Mixture? • Fructose, a fruit sugar found in many plants

50. Compound or Mixture? • Sulfur dioxide combines with water to form acid rain
