Boyle`s and Charles`s Gas Law Virtual Lab

Teacher: Jeff Stellitano
Intended Audience: Conceptual Chemistry (Sophomores)
Timeline: One Double Lab Period
SWBAT: compare and contrast data trends of Boyle’s law
and Charles’s gas law as well as contrast the graphs by
working in Excel
Materials: computer lab, textbooks, syringes, excel sheets
Activities: In the first period of lab students work with
textbooks and gas syringes to determine a relationship
between pressure and volume for Boyle’s Law
During the second period of lab students collect and analyze
data on pressure, volume, and temperature of gases and
generate graphs using Excel
Closure: Teacher asks students the relationships they
observed and some application questions to verify
understanding, lab report
Goals:
To understand the broad effects of temperature and
pressure on the volume of a gas
To appreciate Excel as a tool to analyze data
Objectives:
Differentiate between the graphs of a direct
relationship versus an inverse relationship
Predict the effects of change in pressure and change
in temperature on the volume of a gas
Effectively collect data from two virtual lab sources
SCI.9-12.5.1.12.B.d - [Content Statement] - Scientific reasoning is used
to evaluate and interpret data patterns and scientific conclusions.
SCI.9-12.5.1.12.B.b - [Content Statement] - Mathematical tools and
technology are used to gather, analyze, and communicate results.
SCI.9-12.5.2.12.C.a - [Content Statement] - Gas particles move
independently and are far apart relative to each other. The behavior of
gases can be explained by the kinetic molecular theory. The kinetic
molecular theory can be used to explain the relationship between
pressure and volume, volume and temperature, pressure and temperature,
and the number of particles in a gas sample. There is a natural tendency
for a system to move in the direction of disorder or entropy.
SCI.9-12.5.2.12.C.1 - [Cumulative Progress Indicator] - Use the kinetic
molecular theory to describe and explain the properties of solids, liquids,
and gases.

Cell reference made and autofill
used to make Excel convert from
Celsius to Kelvin
Kelvin values automatically
calculated as Celius values inputed
A lab report is used
which has students
draw a rough
sketch of their
graphs to help
retention through
repition. Students
also answer
application
questions to force
higher order
thinking
Sense and Meaning
Simply telling the students about these laws makes them
meaningless
Including real-life examples and having them interact
personally with the data themselves ensures efficient learning
Chunking
The material is chunked to initially only introduce
students to the gas laws themselves and not yet perform
calculations
Its important that the students first grasp the general
relationship shown by temperature and volume as well
as pressure and volume
This particular student population needs the material at
this pacing
Multiple Intelligences
Bodily kinesthetic – this type of student
Enjoys working with the syringes hands on
and working with the keys and mouse
Visual spatial – this type of student likes to
see the gas compressed
Interpersonal – this type of student likes
working with their lab partner
Logical mathematical – this type of student likes working with the numbers
involved
Lobes
The frontal lobe is used for decision
making.
The occipital lobe is used to interpret
the visual stimuli during this lab
activity
The parietal lobe is stimulated by the calculation being done in this lab
