Physical Science Unit 1 – Safety, Inquiry and Application/Engineering Design

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.

9/8/14 Entry Task Describe 3 important safety procedures in the science lab. Turn in your signed Syllabus! Please take out your materials for the class. 3 points if you have: comp book, calculator, 3 ring binder with dividers.

Safety Rules #1-53 and Contract Safety Cartoon – For each of the numbers on the cartoon, write down the RULE # which was violated. – not_to_do_600.pdf not_to_do_600.pdf – WORK TIME while I check materials. – TRY TO USE EACH RULE AT LEAST ONCE!!! Flinn Safety Video

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

9/8/14 Exit Task Is horseplay a good activity in the science lab classroom. Why or why not? Finish your safety cartoon as homework – due start of class tomorrow for TRADE AND GRADE.

9/9/14 Entry Task Describe location and important aspects of 3 safety features in the classroom. Take out safety cartoon. Trade and Grade. If they have one rule # per cartoon # = 1 point.

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.

9/9/14 Exit Task NO exit task…we are taking a SAFETY QUIZ!

9/10/14 Entry Task What is the unit of METRIC measurement for MASS? VOLUME? DISTANCE? How is metric different than the American system of measuring?

Today’s Agenda Set up notebooks Notes on Measuring and Metric How to Graph using variables. Make a graph using this 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 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 Micro (µ) = 1/1,000,000 or Nano (n) = 1/1,000,000,000 or

KILO 1000 Units HECTO 100 Units DEKA 10 Units DECI 0.1 Unit CENTI 0.01 Unit MILLI Unit Meters Liters Grams CONVERTING with the Ladder Method How do you use the “ladder” method? 1 st – Determine your starting point. 2 nd – Count the “jumps” to your ending point. 3 rd – Move the decimal the same number of jumps in the same direction. 4 km = _________ m 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

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, cm 3 (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

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. Manipulated Variable Responding Variable

Graph this on the graph paper! Number of Surviving Giardia Cysts TEMPERATURE OF WATER (C) Trial 1Trial 2Trial 3Average (averaged results of the RV) Experimental Control Condition 22 (room temp)
