• 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?

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.

a.k.a The Metric System

Please take notes and keep them in your binder for Unit 1 – Science and

Measurement

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

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

Word Parts

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

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

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.

Controlled Variables – per 1

• 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.

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.
