Elements, Compounds, Mixtures.

Elements, Compounds, Mixtures. Ms BolognaMonday: Chickasaw Challenge1. 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 weekExmaple of a word web. 2Assessment 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 dataClass PledgeWe WillWork Hard NOT because we have to but because we WANT to for our own success and future.We CanAchieve excellence through hard work and motivationWe AllWork together to reach our greatest potential Our FutureIs college bound!!!

Why do we say the pledge every morning so that we are learning to become independent learers. 4SWBAT differentiate between elements and molecules. SPI 0807.9.3 Classify common substances as elements or compounds based on their symbols or formulas.Daily Objective

Why did I choose the picture on the right..

Think, pair, share.. What is similar different Etc. 5Rapid ReviewFind 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 whisperSpread your self around the room. Sit with partner when you think you have found your match. The room should have a BUZZ!! No louderBest class will get 3 links on Tuesday.

7Explain to me.. Where do you think that we are going next.

Molecular Compounds1. Two or more different elements are chemically joined

8Compounds2. When they are chemically combined, new chemical bonds form between them.

9CompoundsThe characteristics (properties) of a compound are different than the characteristics (properties) of their component parts (of the elements that make them up)

10CompoundsCompounds have a definite ratio. If I change the ratio, I completely change the properties of a compound.

CO2-Carbon Dioxide CO-Carbon monoxide

11Carbon dioxide is a natural waste product of the process of respiration in living cells and so it tolerated to some extent in the body. It is a waste product and it is excreted when we breathe out. In contrastcarbon monoxide is a poison that forms a stable compound with haemoglobin in the blood and prevents oxygen getting to the body. It kills within minutes in high concentrationsWhat Ways Might I have to Identify CompoundsSymbols??Di= 2Mo=1CarbohydrateCarbon dioxideSodium fluorideCarbon monoxide

MoleculesMolecules are different than compounds. They are composed of 2 elements but they are the SAME element.

Ex 02, C5,

Think , pair, share: turn around to your partner and explain in detail what a compound is. Check your partners defintions. Add something if you need to and delete something else if you need to.

Partner 2: Explain the differenece between a compound and a molecule. 13Give one, Get OneYou 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. Expectations:CoachingOne partner at a timeEntire board should be filled. 14Create 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 3Must write down the script10 minutes total to complete and practice. Must provide an example of each. Record some people at the end. Tuesday: Chickasaw Challenge1. Out of all the families which are the most reactive?Noble GassesTransitionAlkai earthAlkali Metals.

2. Which of the following represents a compound?A. H2 B. NH3C. O3 D. N215. Which of the following materials is composed of only one kind of atom?A. WaterB. Helium C. Air D. SugarAnswer each of the questions and explain why each answer choice (a,b,c,d) is correct or false.

20What are some differences between

21ON the sticky note write 3 observation that you think differentiate between mixtures and compounds based on these pictrues

Share your sticky note with partner behind youMixturesTwo or more substances are physically combined

The substances in a mixture retain (keep) the properties that they originally had

22MixturesPhysical properties can change, but there is no new substance that is formed

No new chemical bonds are formed

Can be easily separated into distinct parts

Examples of MixturesSalt waterTrail mixGraniteSandSoilConcreteSalad dressingKoolaid

24Magic RuleStep 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?

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.

26Jury DutyYou decide!!Element, Mixture, or Compound

27RulesYou must decide if the following are elements, compounds, or mixturesMs. 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!

28Example CaseGood 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

29Think, pair, share.. What is in a good case? Bad case??Case #1Our atmosphere is made up of mainly nitrogen (N2) and oxygen (O2) gases

30Case #2Rust

31Case #3The water in this swimming pool

32Case #4Stainless steel: contains iron, carbon, chromium, and nickel. Carbon gives it its hardness. Chromium and nickel it give a silvery look.

33Exit Ticker Cold Call

Which of the Following is a Mixture. 2. Give one example of amixture. Justify why it is a MixtureNOT a compound.34Wednesday: Chickasaw Challenge1. Create a Tri-Venn Diagram comparing Elements, compounds, and mixtures. Be sure to provide examples of eachClass PledgeWe WillWork Hard NOT because we have to but because we WANT to for our own success and future.We CanAchieve excellence through hard work and motivationWe AllWork together to reach our greatest potential Our FutureIs college bound!!!

Check your examples with a partner and make sure they are correct.

Place on the correct posters! Types of MixturesHeterogeneousHomogeneous

39What does the word hetro mean? Think of another word. What does the word homo mean think of another wordTwo Types of MixturesHeterogeneous MixtureA mixture that does not appear the same throughoutHetero=differentExamples:GraniteChex mixOil and waterHomogenous MixtureA mixture that appears the same (uniform) throughoutHomo=sameExamples:Salt waterKoolaid

40Three Types of Homogenous MixturesSolutionSuspensionColloid

41SolutionsA solution is a mixture that appears to be a single substance.

42SolutionsIn a solution, the solute is the substance that is dissolved. The solvent is the substance in which the solute is dissolved.

43Examples of SolutionsLiquid solutions: soft drinks, gasoline, and tap water.

44HomoSuspensionsA 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.

48Compound or Mixture?Fructose, a fruit sugar found in many plants

49How did you know?Compound or Mixture?Sulfur dioxide combines with water to form acid rain

50Compound or Mixture?Oil and water

51MEach of you will have a card decide if you think that it is a compound or not and be prepared to explain why!
