  1. Thursday, October 25, 2012 Friday, October 26, 2012 Thursday, October 25, 2012 Friday, October 26, 2012 • Water Quality Indicators/Treatment Quick Check • Water Droplet Obituary Create your “Water Droplet Obituary” Warm Up: Take out the EOG Prep Book, place it between you and your should buddy and turn to page 157. Read Chapter 21 silently. Answer “Lesson Review” Questions 1-3 Also, answer the “Discussion Question” on page 160. *LAST SCIENCE CLASS OF THE 1st QUARTER!* • Water Droplet Obituary – Describes the series of locations, events and experiences that droplet had in its “lifetime”. • Possible Starting Points: • Headwaters of Catawba River Basin • Precipitation from a rain cloud into a forest • Puddle near a factory • Hydroelectric Power Plant at Lake Norman • Carowinds Water Park • Possible Ending Points: • Pfiesteria infested swamp • Hog waste lagoon • In a bottle from a drinking water treatment facility • Waste water treatment center • Puddle in front of JMR • Homework: • Create your Water Droplet Obituary • Be sure to include • A specific start point • Your path through the water cycle • A specific end point Page 41 Page 42

  2. Tuesday, October 30, 2012 Wednesday, October 31, 2012 Tuesday, October 30, 2012 Wednesday, October 31, 2012 • Intro to Chemistry and Atoms Read Section 1.1 of Unit D in Text Answer Q 1-3 Warm Up: Wait for video questions Chemistry – The study of matter and atoms and the changes they can undergo Atoms – The building block and basic unit of all matter - Consist of a small charged particles Subatomic Particles – Atoms contain charged particles NucleusElectron Cloud (rings) Positive – Protons Negative – Electrons Neutral – Neutrons Parts of an Atom : Electron Cloud • Homework: • 1. Read Section 1.1 of Unit D in Text Answer Q 1-3 Nucleus Page 43 Page 44

  3. Connection to the Periodic Table of Elements (p. 20 D) Atomic Number – Number of Protons - This is how elements are arranged on the periodic table Neutral Atom –Protons = the number of Electrons Atomic Mass Number – Number of Protons + Neutrons - The total mass of the nucleus 6 C Carbon 12.001 Atomic Number = # of Protons / Electrons Symbol = 1st letter always capital Atomic Mass = Protons + Neutrons

  4. Reading Atoms on the Periodic Table 16 S Sulfur 32.066 13 Al Aluminum 26.982 11 Na Sodium 22.990 Protons: Neutrons: Electrons: Protons: Neutrons: Electrons: Protons: Neutrons: Electrons: Page 46

  5. Atomic Structure Notes Continued Bohr Model - model that shows where particles are located in atoms. Valence electrons – outermost energy level Carbon: 6 Protons How many valence electrons? 6 Neutrons 6 Electrons Page 46

  6. Bohr Model Practice: Use the information to make a Bohr model Carbon: 6 Protons 6 Neutrons 6 Electrons Nitrogen: 7 Protons 7 Neutrons 7 Electrons Oxygen: 8 Protons 8 Neutrons 8 Electrons Page 46

  7. Practice: Determine Protons, Neutrons and Electrons, Draw a Bohr Diagram 12 Mg Magnesium 24.305 5 B Boron 10.811 10 Ne Neon 20.180 Page 46

  8. Thursday, November 1, 2012 Friday, November 2, 2012 Thursday, November 1, 2012 Friday, November 2, 2012 • Practice Bohr Models • Finish Pure Substances vs. Mixtures Graphic Organizer • Bohr Models • Pure Substances vs. Mixtures • Warm up: • Atoms of the same element are alike / different. • Protons are positive / neutral / negative. • Protons are inside / outside the nucleus. • Neutrons are positive / neutral / negative. • Neutrons are inside / outside the nucleus. • Electrons are inside / outside the nucleus. • The overall charge of the nucleus is positive / neutral / negative. Pure Substances – same composition throughout (atoms, elements, compounds) Mixtures – physical combinations • Homework: • Practice Bohr Models • Finish Pure Substances vs. Mixtures Graphic Organizer Page 45 Page 46

  9. Monday, November 5, 2012 Wednesday, November 7 2012 Monday, November 5, 2012 Wednesday, November 7, 2012 • Finish Periodic Table worksheet • Introduction, Organization and History of the Periodic Table Warm up: Determine what element this Bohr model is representing. How did you come to this conclusion? Draw a Bohr model for Helium and Neon – can you make any observations that make these two alike in any way? Make a t-chart and compare and contrast mixtures and pure substances. • Homework: • Finish Periodic Table Worksheet • - Parts 1 and 2 ONLY Page 47 Page 48

  10. Matter • Has mass or weight • Takes up space (volume) • Cannot occupy the same space as other matter at the same time • Pure Substances • Has the same composition throughout • Can Occur Naturally • Mixtures • Formed when two or more substances are physically combined • Parts can be physically separated • Substances in a mixture retain their original properties • Element • Cannot be broken down into simper substances • Compound • Chemical combination of two or more different elements • Cannot be physically separated • Properties are entirely different properties of each element alone • Homogeneous • Parts of the mixture are evenly distributed • Heterogeneous • Parts of the mixture are not evenly distributed

  11. Group or Family(All have same number of valence electrons) Non-Metals Nobel Gasses Period or Row(One proton is added from left to right) Metaloids Metals

  12. Chinese Periodic Table

  13. Chemistry Careers • Food Chemistry • Make up • Gatorade • Fireworks • Forensic Detectives • Pharmacist • Cologne/Perfume • Toothpaste/mouthwash/hand lotion, etc

  14. Thursday, November 8, 2012 Friday, November 9, 2012 Thursday, November 8, 2012 Friday, November 9, 2012 • Periodic Table Families – Part 3 • Metals, Non-Metals and MetalloidsPeriodic Table Basics Activity • Finish Periodic Table Basics Activity • Warm Up: • Identify each container as a beaker full of elements, compounds, heterogeneous mixture or homogeneous mixture. • Homework: • Finish Periodic Table Basics Activity Page 49 Page 50

  15. Families of Elements on the Periodic Table – Part 3

  16. Metalloids Properties of …. Non-metals • Most are gases • Solid non-metals are brittle • Not shiny, but dull • Poor conductors of electricity and heat • Tend to gain electrons in chemical reactions Metals • Most are solids • Can be shaped & pulled into wires • Shiny / lustrous • Good conductors ofelectricity/heat • Tend to lose electrons in chemical reactions • Most are Solids • Can be shiny or dull • Can be shaped & pulled into wires • Conductsbetter than nonmetals but not as well as metals

  17. Tuesday, November 13, 2012 Wednesday, November 14, 2012 Tuesday, November 13, 2012 Wednesday, November 14, 2012 • History of the Periodic Table • Periodic Eggs/Atomic Cube Activities • Study for Quiz • History of the Periodic Table • Dimitri Mendeleev (1834 – 1907) • Siberian • Founded the periodic table (1869) • Organized by Atomic Mass and properties • Could predict where new elements would go on the table • Henry Moseley (1887-1915) • Studied elements using x-rays • Was able to slightly reposition the periodic table because he could see protons • Killed in WWI at age of 28 • Britain made a policy that restricts scientists from fighting in wars • Warm Up: • What are some characteristics the “Carbon Family” shares? • Homework: • Study for Quiz on Atomic Structure, Periodic Table and Pure Substances/Mixtures next class Page 51 Page 52

  18. Mendeleev’s Original Periodic Table

  19. Moseley’s Modern Periodic Table

  20. Thursday, November 15, 2012 Friday, November 16, 2012 Thursday, November 15, 2012 Friday, November 16, 2012 • Nuts and Bolts Activity • Announced Chemistry Quiz • Reflect on 1st Quarter – Make a T-Chart • Warm Up: • Create a concept map that has the topic of Chemistry in the middle and branches out into Atoms, Periodic Table, History and Matter. Then expand on each topic. • See below for example: Periodic Table Atoms Chemistry History Types of Matter • Homework: • Reflect on 1st Quarter, especially your science grade, and crate a t-chart that lists things you did well with and things you need to improve.
