  1. Physical Science Semester One

  2. 9/4/13 • Syllabus • Materials and Parent Signature due Monday Sept 9 • Cards – a little about you…. • Room Tour

  3. FRONT OF CARD BACK OF CARD What do you love about science? What scares you in science? What grade do you hope to achieve? Name one of your strengths Name one of your challenges If you could have a superpower, what would it be? • FIRST AND LAST NAME • Period #

  4. 9/4/13 • Extra Time: • Share info from cards with neighbor • Ice Breaker – 3 Truths and 1 Lie

  5. Daily Entry and Exit Tasks– to learn and assess your progress towards standards: • Enter quietly, gather your supplies, and be seated before the bell rings. • Answer the question(s) from the board on your Entry Task Answer Sheet. • You may help each other with the entry task but not the exit task. • Entry task and exit task are worth 20 points per week. • Last 5 minutes for exit task. You may not help each other or ask me. This is to assess how well you understood the material of the day. • You will “trade and grade” at the end of class each day. The grader’s signature verifies they graded honestly! • You will tell me your score each day. Turn in your entry/exit task answer sheet on FRIDAY each week. • If absent, look on my website to complete these tasks.

  6. Week of 9/4-9/69/5/13 • Entry Task • How many points a week are the entry/exit tasks worth? • When are your syllabus signature and materials due? • NOTE – you can buy a comp book for $1.00 from ASB

  7. Today’s Agenda • Rules and Expectations – (2nd period also go over student handbook) • Hall Passes • Brains are wired differently! (Dr. John Medina) • Multiple Intelligences Survey – turn in bar graph and reflection- http://surfaquarium.com/MI/inventory.pdf (Dr. Howard Gardner) • Look at website for deeper explanations of how you might use this information to be most successful in your learning! • http://surfaquarium.com/MI/profiles/index.htm

  8. Key: • Section 1 – This reflects your Naturalist strength • Section 2 – This suggests your Musical strength • Section 3 – This indicates your Logical strength • Section 4 – This illustrates your Existential strength • Section 5 – This shows your Interpersonal strength • Section 6 – This tells your Kinesthetic strength • Section 7 – This indicates your Verbal strength • Section 8 – This reflects your Intrapersonal strength • Section 9 – This suggests your Visual strength • Remember: • Everyone has all the intelligences! • You can strengthen any intelligence! • This inventory is meant as a snapshot in time – it can change! • M.I. is meant to empower, not label people

  9. 9/5/13 • Extra Time: • Check out brain rules: • http://www.brainrules.net/about-brain-rules

  10. Exit Task Instructions • Last 5 minutes for exit task. You may not help each other or ask me. This is to assess how well you understood the material of the day. • You will “trade and grade” at the end of class each day. The grader’s signature verifies they graded honestly! • You will show me your EXIT score each day as you exit. Turn in your entry/exit task answer sheet on FRIDAY each week. • If absent, look on my website to complete these tasks. • OUR FIRST EXIT TASK is very low stakes – you cannot get it wrong unless you refuse to do it • All the rest will be based on the standards you will be meeting this year

  11. Integrity • Exit – The grader’s signature verifies that they have graded honestly. The exit tasks will be completed individually without help from anyone. A zero for the week will be given to any grader or student assisting in cheating on the exit task. It is expected that we help one another and share answers on the ENTRY task but not the EXIT task.

  12. 9/5/13 • Exit Task • How might you use the information you gained from the MI survey to help you succeed in this class or other classes?

  26. The International System of Measurement a.k.a The Metric System Please take notes and keep them in your binder for Unit 1 – Science and Measurement

  27. The Power of 10 • A system of measurement based on multiples of 10 • Measurements include a base unit and a prefix • Base units in the SI system include: • Length in meters • volume in liters • mass in grams • The prefix refers to a multiple of ten

  28. Prefixes • Kilo (k) = 1000 • Hecto (h) = 100 • Deka (dk) = 10 • Base unit = 1 • Deci (d) = 1/10 or 0.1 • Centi (c) = 1/100 or 0.01 • Milli (m) = 1/1000 or 0.001 • --- • Micro (µ) = 1/1,000,000 or 0.000001 • --- • Nano (n) = 1/1,000,000,000 or 0.000000001

  29. Word Parts • What would a KILO – METER be? • Answer 1000 meters. • How about a CENTI – METER? • Answer 1/100 of a meter.

  30. 1 2 3 MetersLitersGrams How do you use the “ladder” method? 1st – Determine your starting point. 2nd – Count the “jumps” to your ending point. 3rd – Move the decimal the same number of jumps in the same direction. Starting Point Ending Point __. __. __. 2 3 1 CONVERTING with the Ladder Method KILO1000Units HECTO100Units DEKA10Units DECI0.1Unit CENTI0.01Unit MILLI0.001Unit 4 km = _________ m How many jumps does it take? 4. = 4000 m

  31. CONVERTING with Dimensional Analysis • Start with what you are given. • Multiply by conversion factors until you have changed it to the unit you want. • Example: • Problem: 1 day = ? seconds • 1 day x 24 hours x 60 minutes x 60 seconds= 1 day 1 hour 1 minute • Cross out all labels that cancel and do the math. 1 day = 86,400 seconds

  32. 9/11/13 • Exit Task • You know a sample is 2500 grams (g). How many kilograms is it? • Remember your homework! It is due on Thursday 9/12/13, start of class. HOMEWORK: Read pages 5-10 and 17-22. Answer Q 1,2,3, 4a, 4b, 5, 6 on page 23.

  33. 9/12/13 • Entry Task • Using the ladder method or dimensional analysis, please convert:1. 250 g = ? kg 2. 35 cm = ? m • Review how to find online textbook. • Please get out your textbook HOMEWORK. • Trade and Grade. Graders sign on top. Turn in.

  35. best answer is around 2.63 cm • to a scientist this number means “between 2.60 and 2.70 cm.” • the last digit, 3, representing the smallest amount, is uncertain, but it is still significant • always “push it” one more decimal place by estimating

  47. 9/16/13Week of 9/16 to 9/20 • Entry Task • If an object was 75 cm in height, how many meters would that be? • Please get out your practice sheets “Conversion Challenge” and “Dimensional Analyses” • Trade and Grade. Graders sign at the top. • across the number means “Correct!” • around the number means “Incorrect”

  48. Today’s Agenda • Remaining safety contracts!? Turn them in!! • Finish measuring lab. • I will be grading your participation as you work. • When finished, answer the Measuring Focus Questions – due tomorrow.

  49. Measuring Focus Questions – ON PAPER YOU CAN TURN IN!! • When measuring, for which digit do scientists expect uncertainty? Explain why it is still significant and should be reported. • Why would you zero a balance before each use? • Why would you zero the weighing dish before placing the substance in it? • When you used 2 different technologies to measure mass or temperature, did the measurements match exactly? Why might they have been different? • List and explain 3 safety rules you followed in this lab.

  50. 9/16/13 • Exit Task • What is the length of this object in cm? • What is the length in m?
