Experiment files can make performing an
experiment with Logger Pro easier for
00:00:10.500 --> 00:00:15.320
both you and your students by simplifying
setting up and running the experiment. An
00:00:15.320 --> 00:00:19.520
experiment file is a collection of graphs
and data tables, as well as data
00:00:19.520 --> 00:00:25.820
collection and analysis settings. As an
example, let's look at an experiment file.
00:00:25.820 --> 00:00:29.840
We've prepared experiment files for each
of the labs in our books. Such as
00:00:29.840 --> 00:00:33.880
Middle School Science with
Vernier or Biology with Vernier. You
00:00:33.880 --> 00:00:38.750
can find these experiment files in the
experiment folder, which is the default
00:00:38.750 --> 00:00:43.000
location when you open a file in Logger
Pro. If you're doing one of our labs, you
00:00:43.000 --> 00:00:47.750
can save some time by just opening the
corresponding experiment file. Logger
00:00:47.750 --> 00:00:52.450
Pro will set up the window with the
appropriate graphs and data tables.
00:00:52.450 --> 00:00:56.410
Likewise, the data collection parameters
will already be set for that particular
00:00:56.410 --> 00:01:04.260
lab. This lab, Frictional
Forces, comes from our middle school
00:01:04.260 --> 00:01:09.160
science book. In it, students drag a
wooden block across a table and use a dual
00:01:09.160 --> 00:01:13.820
range force sensor to measure the force of
friction. This experiment file is already
00:01:13.820 --> 00:01:19.120
set up to run that lab. It's set to run
for three seconds, the duration of each
00:01:19.120 --> 00:01:23.590
trial. The graph scale is already set up
for the magnitude of force you'd expect.
00:01:23.590 --> 00:01:29.300
The one thing you'll notice is that the
background has been set to the same color
00:01:29.300 --> 00:01:33.390
as the lab book cover. This is
true for all of these prepared experiment
00:01:33.390 --> 00:01:37.630
files. It's an easy way for you to verify
that your students opened the correct
00:01:37.630 --> 00:01:43.440
file. Notice that these experiment files
do not contain any data yet. They are
00:01:43.440 --> 00:01:50.570
really just a template for the lab.
Students collect and analyze data, then
00:01:50.570 --> 00:01:56.050
save their experiment file to a new name.
Later they can open their file and
00:01:56.050 --> 00:02:00.770
retrieve that data or print off graphs.
You can create your own
00:02:00.770 --> 00:02:05.910
experiment files, too. Just set up a lab
and adjust the data collection parameters,
00:02:05.910 --> 00:02:09.960
the data tables and graphs as you'd like.
Run through the lab yourself until you're
00:02:09.960 --> 00:02:15.370
satisfied. Then clear out the data using
the Clear All Data feature in the data
00:02:15.370 --> 00:02:21.320
menu. Save it to an easily accessible
location such as network drive. In class,
00:02:21.320 --> 00:02:25.130
point your students to your experiment
file. They'll be able to do the lab just
00:02:25.130 --> 00:02:30.260
as you did. Experiment files are a
convenient tool to keep in mind as you
00:02:30.260 --> 00:02:34.520
plan lab activities for your
students. Look for other Logger Pro
00:02:34.520 --> 00:02:38.451
videos like this one to help you get the
most out of your Vernier sensors.
