Slide 2 Classification of Matter A Self Guided Lesson Slide 3 Types of Matter Heterogeneous Mixtures Homogeneous Mixtures Compounds Elements When youre ready Quiz Yourself References & Resources Meet the Author Slide 4 Who Helped? Addison Wesley Chemistry (p. 8-15) Free Clipart Junction http://www.cksinfo.com/index2.html Google.com image search Heath Chemistry (p. 39-49) Microsoft Office Online http://office.microsoft.com/clipart/default.a spx?lc=en-us Online resources Slide 5 Resources Summary and Practice http://www.fordhamprep.org/gcurran/sho/sho/les sons/lesson14.htm http://www.fordhamprep.org/gcurran/sho/sho/les sons/lesson14.htm Review and Practice http://teacherbridge.cs.vt.edu/public/bhs/teachers /Dana/Matter.html http://teacherbridge.cs.vt.edu/public/bhs/teachers /Dana/Matter.html Alternative Classification Scheme http://nobel.scas.bcit.ca/chem0010/unit2/2.4_clas sMatter_scheme.htm http://nobel.scas.bcit.ca/chem0010/unit2/2.4_clas sMatter_scheme.htm Quiz Slide 6 Who Am I? Chemistry Teacher Forensics Teacher Son Older Brother (8, 18, 24) Baseball Coach Science Fair Advisor Chemistry Club Sponsor Slide 7 Heterogeneous Mixtures Type of matter consisting of at least two parts physically combined Visible parts Varying composition Impure Physically separable Slide 8 Heterogeneous Mixture Examples DirtHeterogeneous mixtures have more than one visible part ConcreteCar Slide 9 How to Decide Do you see only one part? (YES/NO) NOYES Heterogeneous Mixtures Homogeneous Mixtures Compounds Elements Slide 10 Homogeneous Mixtures Matter that is uniform throughout Referred to as a Solution 1 visible part (uniform distribution) Constant composition Even distribution of particles Slide 11 Solution (Homogeneous Mixture) Examples Salt waterBrass GlassSolutions appear to be one part, but are actually just mixed very well Slide 12 How to Decide Is the matter pure? (YES/NO) NO YES Heterogeneous Mixtures Homogeneous Mixtures Compounds Elements Slide 13 Compounds Homogeneous matter that is made of more than one type of atom Constant composition Fixed ratio Pure 2+ elements in formula SUGAR Pure water Slide 14 Compound Examples Table Salt (NaCl)Compounds are pure matter that consists of two or more elements chemically combined Carbon Dioxide (CO2)Silver Nitrate (AgNO3) Slide 15 How to Decide Is there only 1 type of element? (YES/NO) NOYES Heterogeneous Mixtures Homogeneous Mixtures Compounds Elements Slide 16 Homogeneous matter that consists of only 1 type of atom Constant composition Pure Only 1 element in formula Slide 17 Element Examples CarbonOxygen Elements are pure matter consisting of only one type of atom Uranium Slide 18 How to Decide NOYES Is there only 1 type of element? (YES/NO) Heterogeneous Mixtures Homogeneous Mixtures Compounds Elements Slide 19 The Big Picture Is there only 1 type of element? Is the matter pure? Do you see only one part? NO YES Heterogeneous Mixtures Homogeneous Mixtures Compounds Elements Quiz Slide 20 Answers Slide 21 Im Ready Ill Practice More
