December 9, 2013 Homework: • STEM Career due tomorrow • Mini- Quiz changed to in class Learning Reflections (I’ll explain) • Finish Section “Fill-in” notes AND Section review questions 1A, 1B, & 2A on pg 53 in textbook Complete on page 49 in notebook (If NOT Finished in class) Do Now: -Write down homework • Take out Text Book and turn to page 48 • Update TOC. (in Science nb) P.47/48 States and Changes of Matter • Take your Lab Notebook from your class bin and return to your seat and quietly wait for directions . Today I will… Demonstrate the phases of matter in a lab activity

2. Changes of State Using your textbook, read and review pages 48-53 to fill in the blanks for notes on p47, States and Changes of Matter. Once completed: Begin Section review questions 1A & 1B and 2 A

3. December 10, 2013 Homework: • Review “Fill- in” notes on Changes of State • Lab Data/ Results assigned Tomorrow: Due Friday Do Now: STEM Career due today! • Open notebooks to page 47/48 & 49: “Fill-in,” notes on the Changes of state Section assessment questions 1A, 1B,2A • Take Lab notebook from bin and take out data table

4. December 11, 2013 Homework: Work on Lab Data Analysis/ Results: Due Friday Do Now: -Write down Homework -Take out lab notebook from class bin- Take out Data Sheets -Staple Data Sheets to Data Analysis/ Results Sheet (I will hand this out)

5. December 12, 2013 • Homework: ***Lab Due Date Changed***Now Due Monday 12/16 • Discover the boiling point and melting point of Three (3) elements on the Periodic table: Write in Notebook pg 51 • Quiz on Thursday 12/19 • Do Now: • Write down Homework • Take out Science notebook: Update T.O.C: Pg 50: Thermal Energy & Phase Change of water, Pg 51: Discover the Bp. & Mp. HW

6. What is thermal energy? The total energy in all of the particles in an object. • The faster the particles move, the warmer the matter can get. • Matter Changes state when thermal energy is added (+) or removed(-) • Examples of thermal energy are stoves and matches.

12. Sample Graph: Phase Change

13. December 16, 2013 • Homework: Study for Quiz: Use class notes, textbook and Study guide. • Complete any missing assignments by Friday • Do Now: • Write down homework • Open Science notebooks to p. 51 • Take out Phase Change Lab • Take Lab notebook from bin and quietly go back to your seat

16. December 17, 2013 • Homework: Study for Quiz: Thursday 12/19: Use class notes, textbook and Study guide. • Complete any missing assignments by Friday • Take Letter Home to Parents • Do Now: • Write down homework • Open Science notebooks to p. 51 • Update TOC: p 52: A Few Review Notes

17. The States of Matter: Warm-upFill in the Chart with :”YES” or “NO” on pg 52

18. At what point do particles of a solid break free from their fixed position?

19. Phase Change • Write your responses in your nb. P 51. • Looking at your elements Boiling point and Melting point. If room temperature is 20⁰ C: Are the elements Solids, Liquids or gases at room temperatures?:

20. December 18, 2013 • Homework: STUDY for quiz Tomorrow 12/19 • May use Venn Diagram to compare and contrast Solids, Liquids, and gases and there change of phase • Bring Textbook/Notebook to class tomorrow • State of Matter: Poem, Song…. Due Friday • Do Now: • Write down Homework • Take Out Notebook , Open to page 51 • Tape, staple, or Glue Hand out in Notebook on page 52 • (I will hand this out)

21. What does our Table Tell Us? • That all substances have a boiling point and a melting point. • All matter can change state (not just water) by adding (+) or removing(-) Thermal Energy. • Adding (+) Thermal Energy causes molecules to speed up. • Removing(-) Thermal Energy cause molecules to slow down. • Every substance has a different melting point and boiling point

22. Melting Point & Boiling Points of different Elements • Why do you think different substances have different melting points and boiling points? • Brainstorm ideas with a partner in your notebook on pg 51 • They all have a different arrangement of molecules that react differently to added thermal energy

23. Phase Change Wrap-up ??: Answer on pg. 52 1) The _melting pointis when the particles of a solid break free from their fixed positions. 2) The phase change from a liquid to a gas is called vaporization, the two ways a liquid can vaporize are __Evaporation_ and _boiling___. 3)_Evaporation__ occurs when only surface particles vaporize (change into a gas). 4) _Boiling__ occurs when vaporized water molecules form bubbles below the surface and rise (occurs at the surface and in the liquid).
