Product Description
This is an excerpt from Amazon's popular line of Bossy Brocci Math and Big Science workbooks! [it's pronounced like "Brawsee"]

Printing should be done in Landscape and DOUBLE-SIDED, with the flip being along the 'SHORT' side.

================================================
Most ELA, Math and Science teachers don't have
more than 100 State Tests on their shoulders
- and they enjoy anywhere from 60 to 90 minutes to teach their class.
But I've been whipping the State
while teaching an average of 110 students per year
- and with only about 38 minutes for science class!

It's a matter of public record:
I've crushed the State by 17 to 32 points, and by an average
of 23 points over a 5-year stretch.

And I'm North Carolina's 2016 Top-Scoring Science Teacher.

I've done this in a
High-Poverty, Title 1 school
in the Appalachian Mtns.
with:
No Teaching Assistants,
No Tutors,
No Remediation Class,
and
No Test-Prep books or programs.

So what are my kids doing???

Bossy Brocci worksheets
================================================
Students will:

1) Complete the Heating Curve/Graph (Phase Change diagram) for Water by writing in the words 'Melting' & 'Boiling' in the appropriate location

2) Analyze the 1st Data Pattern Table comparing the Latent Heat of Fusion (Enthalpy of Fusion) of water as Ice to 15 other substances:
Mercury
Gold
Chloroform
Silver
Acetone
Methanol
Ethanol
Heptane
Copper
Glycerol
Iron
Nickel
Aluminum
and
Ammonia

3) Analyze the 2nd Data Pattern Table comparing the Latent Heat of Vaporization (Enthalpy of Vaporization) of Water and 11 other substances:
Chloroform
Mercury
Diethyl Ether
Acetone
Isopropanol
Ethanol
Glycerol
Methanol
Ammonia
Iron
and
Aluminum

4) Use the Data Table on Latent Heat of Fusion and the Equation Q = m(Hfus) [where m is mass] to Calculate the Joules of absorbed heat Q in a 3rd Data Table for 10 grams of melting:
Chloroform
Acetone
Methanol
Ethanol
Heptane
and
Ice

5) Use the Data Table on Latent Heat of Vaporization and the Equation Q = m(Hvap) [where m is mass] to Calculate the Joules of absorbed heat Q in a 4th Data Table for 10 grams of boiling:
Chloroform
Acetone
Isopropanol
Ethanol
Methanol
and
Water

6) Draw and Label a pre-scaled Vertical Bar Graph of Total Joules Absorbed from their calculated results in the preceding Q Fusion Data Table

7) Draw and Label a pre-scaled Vertical Bar Graph of Total Joules Absorbed from their calculated results in the preceding Q Vaporization Data Table

8) Answer 21 Multiple-choice questions based on their Calculations & Observations in the preceding Data Tables and Graphs/Charts

9) Calculate & Record in a 5th Data Table Total Joules of Heat Q absorbed for:
10 g of ice warming up from -100 to 0 Celsius
10 g of ice melting
10 g of water warming up from 0 to 100 Celsius
and
10 g of water boiling

10) Answer 4 Multiple-choice questions directly beneath their Calculations & Observations in that 5th Data Table

11) Answer the Bonus question why a steam burn is worse than a boiling water burn

12) Draw a total of 12 vertical Bar graphs in 2 Charts

13) Fill-in a total of 34 cells in 4 Data Tables or Figures

14) Answer a total of 25 Multiple-choice questions

15) Discover that Ice has a remarkably High Latent Heat of Fusion (Enthalpy of Fusion) - and its implications/importance

16) Discover that Water has a remarkably High Latent Heat of Vaporization (Enthalpy of Vaporization) - and its implications/importance

17) Be compelled to present their work in a neat & orderly format

18) Be trained to define & describe Water's High Latent Heats (Enthalpies) of Fusion & Vaporization and the consequences/importance thereof methodically & systematically
====================================================
NOTICE:
Many of my assessments (Quizzes and Tests) are single-spaced and double-sided.
I do this for multiple but important reasons:

1) I'm a Public School teacher and have a Print Quota or Maximum.

2) My school pays for the number of sheets we print and copy.

3) I don't like spending my life at the printer or in the dreaded copy-room,
wrestling with jammed machines, and stapling untold numbers of sheets together.

4) MOST students prefer being handed 1 or 2 sheets of paper,
instead of having 6 to 10 sheets dropped on their desk.
LESS sheets = LESS intimidation and anxiety
[psychologically, 50 questions on 1 sheet looks like less to do
than 50 questions spread over 4 sheets of paper].

Thus, I went with the "compact economy" car over the spacious, luxurious sedan to save:
PAPER
TIME
MONEY
and
SANITY

So . . . now that you're aware of my "tight" or "compact" quizzes and tests ahead of time,
for something such as a step or instruction that you were truly CONFUSED about
- - - NOT the lack of extra spacing and margins (which you knew up front weren't in there)

Afterall . . . it wouldn't be a fair, honest or accurate review
to condemn a car for not being a luxury sedan - - -
when in fact that car is plainly advertised as an economy car.
