• Introduce Entry/Exit procedures• My Expectations• Syllabus review• Classroom Tour• SAVE SAM activity• Set up notebooks (Finish Tuesday)

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 Sheet. You may help each other with the entry task. We will discuss and you should copy answers you did not have.

• 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” during Exit Task most Fridays. The grader’s signature verifies they graded honestly!

• Entry task and exit task are worth 20 points per week.• Turn in your entry/exit task answer sheet on FRIDAY each week. • If absent, look on my website to complete these tasks.

9/14/15

• Entry Task

• Find Ms. Maring’s expectations poster. Describe location.

• NOTE: during exit task time, I will be checking that you brought your supplies.

Classroom tour

• Blue lines• Emergency panel and fume hoods• Turn in trays• Crates with copies – best to check my website. • Lab Stations - #1-8• NO NAME baskets – add name, turn it in.• Eyewash and Fire extinguisher and exit door• Performance Expectations on board

Only You Can Help Save Sam!

Sam has been spending his summer boating on the great lakes. However, he’s not too bright (after all, the brains of worms are pretty small). He’s never learned how to swim, and he never wears his life preserver. The worst has happened! His boat has capsized and he’s stuck! Fortunately, his life preserver is in the boat, but unfortunately he does not know how to reach it without falling off and drowning.

Use the Scientific Method to solve the problem…

How can you and your partner save Sam using only 4 paper clips. You may not touch Sam, the boat, or the life preserver directly with your hands.

Saving Sam

• Materials:• Gummy Worm• Gummy “Life Saver” preserver• 1 Plastic Cup• 4 Paper Clips• Your task:

– Work with your partner and "Save Sam".– Follow the rules.

• Sam, the boat, the life preserver can be touched only with the paper clips. NO HANDS.

On a piece of notebook paper…

–Develop a data section that includes•Diagrams of how you saved Sam•A detailed procedure your steps to

success.–Analyze and conclude the experiment.

–Tell me about the difficulty of the task–what other strategies you and your partner

worked on before you succeeded– and what you think the critical steps were

for solving this problem.

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.

• When you have an answer written down, raise your hand and I will come stamp your paper.

• 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

9/14/15

Storage

• You may either keep the notebook with you or leave it in the cupboard for your class period

• If you take it home – don’t forget to bring back every day

• If you forget your notebook, please get a C-Notes paper (in the rack) before class starts and transfer or tape the notes into you notebook.

• If you store your notebook here, please respect other students’ property by leaving the other notebooks alone!

If you are absent…

• Class notes and activities are posted on Ms. M’s teacher page

• BE RESPONSIBLE and add the information to your notebook.

Safety HOMEWORK

• Rules #1-53 and Contract• Safety Cartoon – RIGHT SIDE– For each of the numbers on the cartoon, write

down the RULE # which was violated. LEFT SIDE– http://expedioscientiam.net/school/resources/wh

at_not_to_do_600.pdf

• REVIEW FOR QUIZ • Last 10 min SAFETY QUIZ.

9/16/15

• Exit Task

• NO exit task…we are taking a SAFETY QUIZ!

• SAFETY CONTRACTS DUE FRIDAY SEPT 18!!!

9/17/15

• Entry Task

• What is the unit of METRIC measurement for MASS? VOLUME? DISTANCE?

• How is metric different than the American system of measuring?

• Would anyone like to bring back the textbook and do the ONLINE version?

• Take out safety cartoon. Trade and Grade. If they have one rule # per cartoon # = 1 point.

Today’s Agenda

• Notes on Measuring and Metric• How to Graph using variables. • Make a graph using given data.

Metric System, Measuring and Graphing

Please take notes on the next RIGHT side page in your COMP BOOK

The International System of Measurement

• a.k.a The Metric System or SI• A system of measurement based on multiples

of 10• Measurements include a prefix and base unit• 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 (1 kilogram (kg) is about the mass of a

russet potato)• Hecto (h) = 100• Deka (dk) = 10• Base unit = 1 (1 gram (g) is about the mass of a paperclip)• Deci (d) = 1/10 or 0.1• Centi (c) = 1/100 or 0.01• Milli (m) = 1/1000 or 0.001 (1 milliliter of water would fill

a 1cmx1cmx1cm cube)• ---• Micro (µ) = 1/1,000,000 or 0.000001• ---• Nano (n) = 1/1,000,000,000 or 0.000000001

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

How many jumps does it take?

Common units of measurements (equipment to use)--

• Mass: g, kg (triple beam balance or scale)

• Distance: mm, cm, m, km (ruler or meter stick)

• Volume: ml, L, cm3 (graduated cylinder)

• Temperature: ºC, ºF, Kelvin (thermometer)

• Time: seconds, minutes, hours (stop watch)

= most common

• 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

• Your calculator answer should have the same number of places as the problem

256.15 g

124.465 g

52.6 ml

GRAPHS• Make a bar or line graph of your results.• MV – conditions become the X-axis• RV – results of the trials, usually the averages only

become the Y-axis.

Surviving Giardia Cysts”• MV labeled with words or numbers on axis.

Tops of bars labeled with “height” (y value)• Make it as big as possible
