Picture of a Lab
– Different Graph Types
Station #1
investigates the relationship
between force and displacement
of a stretched spring. Students
will discover a direct linear
relationship, with an equation
of the form y = mx + b. Station
#2 demonstrates Boyle’s Law, or
the relationship between the
pressure on a gas and its
volume. The graph is a
hyperbola, y = 1/x. Station #3
relates light intensity to
distance from the source. The
graph shows an inverse-square
relationship, with an equation y
= 1/x2. Station #4 uses
staggered, stacked blocks to
result in a simple parabolic
graph, where y = x2.

Recommended quantity per lab
group: 1
The "Computer with Excel or
other graphing application"
required for this lab is any
computer that you may have that
has software capable of plotting
graphs. In order to use the data
logger in this experiment, the
computer would need to be of PC
version (Windows). |
|
Recommended quantity per lab
group: 1
The "Several
identical weights or books"
required for this lab are any
objects that you may have or that can also be
purchased from your local
convenience or hardware store
that are identical in weight. |
|
Recommended quantity per lab
group: 7
The "wood
blocks"
required for this lab can be cut
from any lumber that you may
have or purchased from your
local building supply store. The
blocks should all be identical
in measurements. |
