## Q1: week 2 – 9/11 – 9/15

” The first day of class should connect to the last day and every day in between!”

Please check Power School for accuracy!

Everyone needs to join Remind for class.  Click me to sign up.

Main focus –

-Show mathematical work, stating formula and steps for solution

Period 6:

1. Quick review of the homework form.
2. Model 2 step conversions – converting between different units – using conversion factors.
3. Student practice of the 2 step conversions using the worksheet below:

______________________________________________                                                                                            9/12 – Tuesday “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.                                    4. To define Accuracy vs. Precision.

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  6:

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

________________________________________________________                                             Jump to / top        9/13 – Wednesday “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  6: –

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

sig fig ditto1 key.pdf

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

Period  7:

LAB 1 Density of Solids.pdf

1. Complete measurements of objects, calculate volumes, density AND ROUND!

2. Determine the accuracy of your calculated Densities = calculate percent error, hand out out reference tables.

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

Significant Figures lesson:  Today’s lesson – part 1

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

9/13 –  Wednesday  “A” Day Homework:

1.  Complete the Measurement and Significant Figures Form below:

1: Measurement and Significant Figures RAT Form:

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

9/14 – Thursday “A” Day –

Main focus:

1. To Round calculates values either by the Accuracy Rule or the Precision Rule.
2. To Round a conversion correctly.
3. To Identify constants as numbers that are not considered for rounding.

Period  6:

1.  We will review the homework form based on the following worksheet.

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

2. Quick review of significant figures and their origin (measurements!!)

3.  We will spend more time reviewing and understanding how and why we round using significant figures (Accuracy Rule) and decimal places (Precision Rule) using the worksheet handed out last Thursday and our class notes.

We will also complete the bottom questions of the sig fig ditto.pdf – Specifically we will use scientific notation to help round number that would normally be impossible.

a) We will also revisit the metric conversion worksheet 2 – AND NOW round correctly!!!!
Remember that we only compare sig figs with measured value. Constants like 3.14 are not used to                                    determine  the rounding.
