  1. Warm-up 10/11/13 • Teach the Teacher: How was the test on a scale from 1-10? What is the best warm drink? • Review: What are things that are good for the brain and learning?

  2. Warm-up 10/18/13 • Teacher The Teacher: What was one of the hardest decisions you had to make? • Review: What did you think about the Uranium mining presentation?

  3. Warm-up 10/20/13 • Teach the Teacher: What is annoying about Facebook status updates? • Review: What is inside an atom?

  4. Warm-up 10/21/13 • Teach the Teacher: What is annoying about Facebook status updates? • Review: What is inside an atom?

  5. Warm-up 10/22/13 • Teach the Teacher: What is your soda of choice? • Review: Will evidence ever have an opinion in it? • Remind me to get a list of people that want to come on Thursday. • Also print powertech thank you

  6. Warm-up 10/23/13 • Teach the Teacher: What is the most creative Halloween costume you have ever heard of? • Review: Describe the states of matter.

  7. Warm-up 10/26/13 • Teach the Teacher: What did you think about the speaker yesterday? Review: What is uranium?

  8. Warm-Up 10/28/13 • Teach the Teacher: What is the best Haunted House thing to go to? • Review: What particles are positive in an atom?

  9. Binder Organization • Flash Card holder • Grade Sheet • Warm-ups • Orange Notes • Graded Assignments for orange notes (lab safety questions, etc) • Blue Notes • Graded Assignments for blue notes (sponge bob etc) • THINGS IN POCKETS: Chem Idol, evidence sheet, Guest speaker evidence reasoning, little evidence/reasoning matching sheet

  10. Warm-Up 10/29/13 • Teach the Teacher: What are you most excited about for becoming an adult? How do you know when you are an adult? • Review: What made the strip of paper fly upwards?

  11. Element Solid, Liquid, Gas, Plasma Words to Know Molecule Chemical Change/Properties Proton Atoms Bernoulli’s Principle Matter Electron Compound Conservation of Mass Kinetic (moving) Molecular Theory Neutron Chemical Reaction Physical Change/Properties

  12. Definition Poster • Vocab Word (large print) • Definition (large print) • Picture (large) • Description of how picture illustrates vocab word • Due Thursday, colored • Best Source: book, but can try looking it up online

  13. independent Variable • PART OF AN EXPERIMENT THAT CHANGES • Experiment: does drinking milk make teeth whiter, Independent variable: drinking milk compared to not drinking milk

  14. What is Uranium?

  15. What is matter? • Anything that has mass and takes up space.

  16. What makes up matter? • Atom=smallest unit of matter • (IT’S, REALLLLLLLY SMALL)! • magnifying the universe Structure of Matter

  17. What makes up an atom? • Protons=positive charge • Neutrons=neutral in a car=no charge • Electrons=electricity= “-” • Nucleus contains protons and neutrons • Quarks could make up protons and neutrons • Electrons orbit around nucleus (kinda like a fan)

  18. Size of atomic particles • Atomic Mass of particles: • 1 neutron about = 1 proton • 1,836 electrons = 1 proton • Lots of empty space in an atom • If bowling ball=proton/neutron • Golf ball= electron • Football field= space in-between addoms family

  19. How is One kind of matter different From Another kind?

  20. Element A substance that cannot be broken down by chemical means 90 naturally occurring elements found on Earth 20+ man made elements (nuclear bombardment) Elements are listed on the Periodic Table Have a different number of protons and electron FORMULA = Only one capital letter Elements vs. molecules vs. Compounds

  21. Molecules • Molecules are two or more atoms joined together of the same element… • Examples: O2, Cl2, etc.

  22. Compounds • Compound • Two or more elements bonded together. • Bond in ratios • Water = H2O it will always have 2 hydrogen atoms for every 1 oxygen atom. • Formula= more then one capitol letters

  23. Warm-up 10/30/13 • Teach the Teacher: What would be the most fun activity to do at a nursing home? • Review: What charge does a neutron have?

  24. Warm-UP 10/31/13 • Teach the Teacher: What is the worst thing anyone has ever gotten tricker-treating? • Review: What is the part of an explanation where you discuss how the evidence supports the claim?

  25. Warm-up 11/4/13 • Teach the Teacher: What was the best Halloween costume of 2013? • Review: What is the part of an experiment that you keep the same?

  26. What Does Matter Do?

  27. Physical Changes/Properties • Physical properties: describe what the element/compound is like just hanging out • Physical changes DO NOT alter the identity of the original substance • A change in size, shape, or state of matter is a physical change “3S”

  28. Chemical Properties/Change • Chemical properties: describe what will happen to an element/compound if something is done or added to it. • The change of one substance to another is a chemical change • 6 Clues that a chemical change has occurred • Color change • Bubbles (not boiling) • New odor • Heat or Cooling • Light • Sound

  29. Chemical Reaction • Chemical change happens during a chemical reaction • Never a change in the number of elements • Conservation of Matter: matter can never be destroyed or created • Energy is always taken in or given off

  30. What are the 4 states of matter? • Matter comes in 4 different states Solid Liquid Gas Plasma Atoms atoms family

  31. Plasma • Plasmas consist of freely moving charged particles • electrons & ions • Plasma is formed at high temperatures when electrons are stripped from neutral atoms • Examples: Sun, plasma Tv’s, Northern lights

  32. Kinetic(moving) Molecular Theory Molecules/atoms are always randomly moving! What happens in gasses Particles collide (but don’t lose energy, no friction) into each other or the walls of the container Particles are not attracted to each other Speed of the particles and number of collisions depends on the temperature of the gas • Solids= very little movement • Liquids= more movement • Gases= lots of movement

  33. Properties of Fluids Bernoulli’s Principle Increased speed of a fluid or gas=decreased pressure Look at picture A=fast moving air B= slow moving air A= less pressure B= more pressure, more pressure pushes on bottom of wing= flying A B

  34. So Uranium
