How Can I Show That My Calculations Are
Correct?




Identify the independent variable,
dependent variable and controlled variable
in a research situation.
Craft a well-written research question that
clearly states the independent and
dependent variables.
Design a simple experiment to explore a
research question such as “How does the
number of Mentos tablets affect the height
of a diet soda geyser?”
How Are Measurements Different from Regular
Numbers?










Recognize the difference between accuracy
(how close measurements are to a “true”
value) and precision (how close
measurements are to each other).






Measure length, mass, and volume with the
correct precision.
Round off long numbers to a specified
decimal place.
Write very large or very small numbers in
scientific notation.
Analyze class data to indicate accuracy
using % error. (Know the formula.)
Write equalities as conversions factors.
1 mile
[ex.,
]
5280 feet
Use “dimensional analysis” to set up
problems that convert one unit to another.
Calculate answers from a dimensional
analysis set up.
Use time facts and metric facts in
dimensional analysis problems.
Identify the Given Value and Desired Unit
in a dimensional analysis problem.
List the three metric prefixes (centi-, milli-,
and kilo-) as conversion factors for Liters
(volume), meters (length), and grams
(mass).
Enter numbers written in scientific notation
into a scientific calculator.
Why Is Density A Useful Property of Matter?



Define density as mass/volume.
Calculate density from measurement data.
Calculate density from a graph of
measurements.
Analyze class data to indicate precision
using  notation or significant figures.
(Know the formula.)
How Can I Organize My Data?
Define significant figures as all those of
which you are certain plus one more that
involves judgment of the observer.



State the number of significant figures in
any measurement.
Round off a calculated answer to the correct
number of significant figures.
State the significant figure rules for  & .
State the significant figure rules for + & .


Make a simple data table with labels, units,
and straight lines.
Recognize a scatter plot versus a bar graph.
State that a scatter plot is appropriate when
a relationship between the independent
variable and dependent variable needs to be
made apparent
Correctly assign the independent variable to
the x-axis of a scatter plot and the
dependent variable to the y-axis.
Draw a proper graph having a title, labels,
units, consistent & appropriate scale.
