Physical Science
Semester One
9/4/13
• Syllabus• Materials and Parent Signature due Monday
Sept 9• Cards – a little about you….• Room Tour
FRONT OF CARD
• FIRST AND LAST NAME• Period #
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?
9/4/13
• Extra Time:• Share info from cards with neighbor• Ice Breaker – 3 Truths and 1 Lie
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.
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
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
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
9/5/13
• Extra Time:• Check out brain rules:• http://www.brainrules.net/about-brain-rules
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
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.

CONVERTING with the Ladder Method
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.
4 km = _________ m
12
3
How many jumps does it take?
Starting Point Ending Point
4.1
__.2
__.3
__. = 4000 m
• 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
CONVERTING with Dimensional Analysis

Today’s Agenda – Part 2
• Follow and record answers in composition notebook for steps 2 in lab manual. STOP before step 3.
• Whole class – share and record data to complete data table “First Trial”
• Discuss
Whole Class – discuss…write answers in composition notebook
• Complete data table using data from each group for trial one.
• Do these results make sense? Why or why not? • What is the experimental or independent variable in this
lab? • List and explain the controlled variables we should have.
Why are these important for valid results? • What is the responding or dependent variable in this lab?• EXTRA TIME? Return to labs and complete Step 4 and 5.
Controlled Variables
• Check height of ramp – is each group in the correct (assigned) hole?
• Top c-clamp on top black mark• Photogates – A on 5th down from c-clamp (next black
mark)• Photogate B – 5 up from bottom c-clamp• Bottom c-clamp on bottom black mark. • Release – make sure round end against c-clamp and
pointy end of car down. Same operator and same release method.
9/23/13

• Why should you only change one variable at a time in a good investigation?
9/24/13
• Entry Task
• Look up the words ACCURACY and PRECISION in your book.
• What do those words mean? How are they different?
Whole Class – discuss…write answers in composition notebook
• Complete data table using data from each group for trial one.
• Do these results make sense? Why or why not? • What is the experimental or independent variable in this
lab? • What is the responding or dependent variable in this lab?• List and explain the controlled variables we should have.
Why are these important for valid results? • EXTRA TIME? Return to labs and complete Step 4 and 5.
Controlled Variables – per 6
• Top C-clamp at the top of the ramp – on first black mark.
• Bottom c-clamp at the bottom of the ramp – on last black mark.
• Photogate A – first black mark down from top c-clamp
• Photogate B – first black mark up from bottom c-clamp
• No pushing just let go of the car to release! With pointy end forward.
• Hypothesis: • If the height of the ramp is highest, • Then the time will be the least• Because the higher angle will cause more
gravity to act on the car.
Controlled Variables – per 4
• C-clamps: top c-clamp on top circle (black square around it)
• Photogate A – on 4th circle down from top c-clamp• Photogate B - 10 circles down from photogate A• No pushing the car – release method should be
same between groups – make sure car is backed up against c-clamp and let go of it.
• Each group have ramp in correct hole.
Controlled variables – per 3
• Release of car should be same between groups – no pushing
• C-clamps should be attached at the very top of the ramp and the very bottom (on top and bottom black circles)
• Photogate A – on 3rd empty circle down from top c-clamp
• Photogate B – on 4th circle down from top c-clamp• Make sure your group has the right hole.
Controlled Variables – per 2
• Distance between photogate A and B should be same across groups.
• Photogate A – on 3rd empty circle mark down from top c-clamp. • Photogate B - on 3rd empty circle mark up from bottom c-clamp• Top c-clamp should be up against top of ramp on first black
mark.• Bottom c-clamp should be down against botton of ramp on
bottom black mark. • Level out yellow bubble as best you can. • Push car up against c-clamp and release in same manner each
time.
Return to lab stations…
• Complete steps 4 and 5 and record answers in composition notebook
• Be sure your results are PRECISE (reproducible) before you share your data.
• Sit down and compile rest of data from all groups into data table for “Second Trial”.
