2: Metric Conversions RAT Form:    Edit question 1 and 2 for next year..

9/8 – Thursday “A” Day –

Main focus:

1. To review the unit conversion 2 step method (factor label)
2. To use the concepts of measurement to gather numbers from measurement devices.

3. To define significant figures and identify greatest precision with them.

Standard 1, Key Idea, M1.1 –
measure and record experimental data in calculations
– choose appropriate measurement scales and use unit in recording
– show uncertainty in measurement by the use of significant figures.

Period  9:

2. Continue with the Measurement lesson using the measurement worksheet that we started yesterday.
Introduce the concept of precision.

Review of Metric Conversion and Measurement Form:

9/9 – Friday “B” Day – Lab –

Main focus:

1. To identify significant figures from a raw number ( a measurement).
2. To round a multiplication or division calculation correctly using significant figures.
3. To round an addition or subtraction calculation using decimal places.
Standard 1, Key Idea,
M1.1 – measure and record experimental data and use data in calculations
– measure and record experimental data…
– choose appropriate measurement scales and use unit in recording
– show uncertainty in measurement by the use of significant figures.

Period  8: –

1. Part 1 LessonDefine a Significant Figure and identify how many significant figures are in a measurement or calculation.  I will use our class notes to teach.

2. Part 2 LessonHow to round calculations based on the type of calculation. I will use our class notes to teach.

Unit 1 – Measurement and Calculations Notes – pgs 1 -10.pdf

3. Continue with Lab 1 – Measure dimensions and mass.  Calculate Volume and Density.

LAB 1 Density of Solids.pdf

Period  9:

1. Lab one – Determine the accuracy of your calculated Densities = calculate percent error, hand out out reference tables.

2.  Use table S to look up the known values of the densities of the metals.

3.  Lab Safety  – sign contract and have a parent sign a copy and turn in for a 100 quiz grade. Safety feature of                                 the room and basic rules of engagement.

Explain the lab Safety Video assignment posted in the homework section below  –

4. Play the safety video (from 1950’s) –   will probably not get to this..

Accidental Explosions – circa 1950’s :

Significant Figures lesson:  Today’s lesson – part 1

How we round in calculations:  Today’s lesson – part 2

9/9 –  Friday – “B” Day homework: –

1.  Complete the Measurement and Significant Figures Form using the following worksheet:

Measurement and Sig Figs – RAT 4 – 22-23.pdf

2.  Lab Safety Lesson–  (this is due Tuesday – 9/13) Use the Lab safety contract pdf that is posted below along with the Youtube playlist and Form to complete this activity.

*Please sign both safety contract copies and have your parents sign one  and hand that one in by Friday. The               handed parent signed copy will represent a quiz grade in powerschool.

The forms are posted below.

1: Measurement and Significant Figures RAT Form:

*Please read question 5 carefully!! It is worded differently than the hardcopy!!

2:  Lab Safety Lesson Use the Lab safety contract pdf that is posted below to complete this activity or the hardcopy I gave you in class.

Regents Chemistry Safety Contract .pdf

In this activity, you will write the safety rule (just one sentence) ,its number from the safety contract (that I gave you and is posted below),  AND WHERE IN THE VIDEO (: timecode) that is demonstrated in four safety videos.  You need 10 different safety rules and you must use 4 out of the 6 videos. This means if you find 7 in the first video you will need 1 each from the three others to successfully complete the activity.  There are many other combinations but you must use 4 videos and you must have 10 different Safety rules written total.

Let me restate: You must find 10 unique safety rules throughout the four of the six videos of your choosing.
YOU MUST ALSO IDENTIFY BY TIMECODE WHERE IN THE VIDEO THE SAFETY RULE IS BEING
DEMONSTRATED, DISCUSSED, OR INFERRED.

1: Jefferson High VIDEO – #45. Examine glassware before each use. (3:23)

I  know what #’s each video covers and where thus will grade your work based on this accuracy.

The video playlist is posted above the lab safety form for your convenience.

As you may have figured it might be easier to write you responses in a word doc then cut and paste it into the form when you are done. This way you have a record which might come useful if there is a issue with submitting.
