As a remote datalogger

Take data anywhere, anytime with
the Xplorer GLX. (And with 12 MB
of memory, that’s a lot of data).
Display and even analyze data on
the Xplorer GLX screen.
Later, simply connect the
Xplorer GLX to the USB
port on your computer and
all stored data is downloaded, ready for writing reports
or further analysis. Xplorer
GLX lets you take data
anywhere, any time and still
have the data available for
use on your computer. Data
can also be stored on a USB flash drive.

Measure resonances or the speed of sound
Choose the Linear Fit Tool, then select the
appropriate region of data. Slope and Intercept
are at bottom of screen.

The Xplorer GLX, with its built-in microphone and 50 Khz
sample rate, lets you look at waves produced
by musical instruments. Students perform many
acoustic experiments. The GLX can even create
its own sound waves, using its dual channel sine
wave generator and built-in speaker.

Calculator

Perform any single calculation or create a calculated
data set based on measurements from a sensor. Any
function can be graphed directly from the calculator
window. Students see both equation and graph.

Two tuning forks of
slightly different frequencies are sounded
together. Now your
students can hear and
SEE the waveforms,
and understand the
concept of beats.

Vary Driving Frequency of a String Vibrator
Power a Speaker for a Resonance Tube

In the experiment shown below, the Xplorer GLX and the GLX Power
Amplifier are used as a variable frequency sine wave power supply
for the String Vibrator (WA-9857). The Force Sensor (PS-2104) is used
to measure the tension in the string. All parameters can be varied,
including tension, amplitude, frequency, and the number of vibrating
segments.

For the Ohm’s Law Experiment shown below, the GLX Power
Amplifier provides a 20 second long voltage ramp, and a Voltage vs
Current graph is generated for a resistor and a light bulb. The CI-6512
RLC Circuit board also includes two capacitors
and an induction coil for performing low
frequency RC and RLC circuit experiments.

Graph shows V vs I data for a 33 Ω
resistor and a light bulb. The slope
of the linear graph gives the
resistance of the resistor. Note the
non-linear graph for the bulb, due to
its large change in temperature.

Digits Display (top screen)
shows the tension in string
when not vibrating.
The bottom screen shows a
graph of frequency vs. number
of vibrating segments. The
slope of this line, along with
the tension and length of the
string, allows calculation of
the wave speed and density
of the string.

PASPORT – GPS

Record Latitude and Longitude of Sensor Measurements
GPS Position Sensor
PS-2175
The GPS Position sensor utilizes satellite
triangulation to determine the sensor’s
position and velocity in outdoor environments. Obtain sensor data simultaneously
linked to your latitude, longitude, altitude,
and velocity.

Two Modes
Absolute Position Mode: Pinpoints
your location in the world and reports the
latitude and longitude with a resolution of
two meters. This data can be imported into
My World GIS™ software to overlay sensor data on maps or aerial photos.

Car acceleration was measured with an Acceleration Sensor, and position and
velocity were measured with the GPS Position sensor, then plotted on an aerial
photo in My World software. The size of the plotted data point indicates the speed
of the car, and the data is color coded to indicate the car’s centripetal acceleration.

Relative Position Mode: This mode
enables a higher resolution (0.2 meters),
suitable for experiments involving bicycles
or people running or walking, in which the
position in the world is not required.

PS-2204

This new Load Cell Amplifier is for applications where only one or
two load cells are needed, such as measuring the force on the track
at the top and bottom of a roller coaster loop. If you only want to
examine the forces in a bridge one at a time, you can move a single
load cell around in the bridge.
The Amplifier accepts either the 100N load cell or the 5N load cell
or a combination of both. The maximum data sample rate is 1000
Hz for each port.
It is also an inexpensive way to add sensors to your structures.
Later, if you want to expand the number of load cells you are using,
you can add another Dual Load Cell Amplifier or a 6-port Load Cell
Amplifier (PS-2198). All PASCO load cell amplifiers can work simultaneously on one computer. A PASCO PASPORT USB interface is
required: Use a USBLink (PS-2100A) for just one Load Cell Amplifier
or use an Xplorer GLX (PS-2002) or PowerLink (PS-2001) for
multiple Load Cell Amplifiers.

The PS-2204 Displacement Sensor
measures the travel of a spring-loaded
indicator pressed against a bridge as
the bridge is loaded. It consists of a
PASPORT sensor which plugs into
the included Digital Indicator, a digital
travel indicator which has its own
digital LED readout and can be used
as a stand-alone device. When the
PASPORT sensor is plugged into a
PASPORT interface, the reading can
be recorded.

A 1-Axis Acceleration Sensor
The Visual Accelerometer provides acceleration data and visual clues that allow
students to better understand the concept of acceleration. The sensor features 10 high
output, wide-angle LEDs that indicate the magnitude and direction of acceleration. The case
of the sensor fits directly into a dynamics cart, and features ties for pendulum motion and a
pass-through so the sensor can be thrown vertically along a rope.
The Visual Accelerometer features three fixed ranges, an auto-scale and a peak-hold option.
The peak-hold mode stores the maximum acceleration experienced by the sensor after a
countdown appears on the LEDs. The zero button on the sensor negates the effect of
changing the orientation of the sensor.
The Visual Accelerometer can also be used in stand-alone mode. While away from the
computer, the LEDs give students a meaningful, visual measurement of acceleration.

Typical Applications
A Real-time measurement of acceleration during simple
harmonic motion
A Measure acceleration due to gravity
A Measure acceleration of a cart on an inclined plane

acceleration in all three dimensions along with changes in altitude.
Students can easily read changes in altitude with 0.30 m resolution.
In addition, all three dimensions of acceleration are automatically
combined by the sensor, making resultant acceleration an available
measurement. Acceleration and altitude can be displayed on the
same DataStudio graph, leading students to a better understanding
of the physics of rides and other outdoor activities.

A For Sense and Control Projects
This relay is a single-pole double-throw switch that is controlled
by DataStudio or an Xplorer GLX. It acts as a switch to turn equipment on or off in sense and control experiments. Some applications
include: Turning off a fan cart when it reaches a certain speed, turning on a lamp when the chicken’s cage gets too cold, or turning on
a motor when a condition is met.
The relay plugs into a PASPORT interface with a Digital Adapter
using a ¼” stereo phone plug. The device to be controlled is connected to two of three banana jacks on the front of the relay: One
jack is the common, one jack is for a normally open connection, and
the third jack is for a normally closed connection.
There is a push-button for manually activating the relay to test your
connection. An LED indicates when the relay is activated.

PASCO’s Goniometer helps
students better understand
physics because they use
their bodies as the experimental apparatus. The
Goniometer can be connected to the knee, hip
or elbow joints to measure angle
changes during a variety of movements. Measure the angular position,
velocity and acceleration for the arm or leg. Use with the Xplorer
datalogger for a compact, easy-to-use human motion lab.
The PS-2137 includes one Angle Sensor (PS-2139) and one
Goniometer Probe with Velcro connection kit. To measure the
motion of two joints simultaneously, simply purchase another
Goniometer Probe separately.

Specifications
Range: 0 to 120º
Accuracy: 2% of measurement
Resolution: 0.25º
Maximum Sample Rate: 500 Hz

Position and velocity

The Human Arm Model simulates the muscles and motion of an
actual human arm. To activate the arm motion, students pull on the
cord with a Force Sensor. Changes in position are measured at the
shoulder and elbow using the two built-in potentiometers plugged
into one Angle Sensor (PS-2139), included with PS-2611.
The Arm can perform many types of motion such as extending and
lifting an object, curling, or throwing a ball overhand. Different arm
muscles are activated depending on which pulleys are selected.
Static force measurements can also be made to see how the
muscle tension changes at various arm positions.
Angles and Forces
During Extension: The
upper graph shows the
angles of the elbow (violet trace) and the shoulder (blue) as the arm is
extended as shown in
the picture below. Shown
in the lower graph, the
bicep tension (red) has
little change at first and
then rises sharply as the
arm reaches out, while
the tricep tension (green)
rises steadily.

The Aquatic Productivity Bottles were completely
filled with algae solution, and the initial dissolved
oxygen (DO) concentrations of the solutions were
determined with a DO sensor. The bottles were
then placed into the rack and the specially molded,
light-varying lid was locked into place over the
bottles. After 24 hours of incubation in fluorescent
light, the bottles were removed from the rack and
the DO concentration was again determined with a
DO sensor. Using the initial and final (DO) , students
calculate Net Primary Productivity and Gross Primary
Productivity.

Typical experiments involving photosynthesis require students to infer photosynthetic
rate changes by using chloroplasts and
dye. Help students understand this concept more completely by directly measuring the production of oxygen.

Water in the outer tank is used to control large
fluctuations in temperature when the light is used.
Students can further their understanding of photosynthetic rates by adding dyes as colored filters.

how the ecosystem responds.

A D
esigned for sensor-based
measurements
PASCO’s EcoZone System is designed to
help students model and understand the
complex interactions within, and among,
different ecosystems. The three clear acrylic
EcoChambers are specially designed to
accommodate PASCO sensors, making
qualitative and quantitative measurements
as easy as observing.

Opening connects the chambers and
allows the interaction between the
living and non-living components of
each unique ecosystem.

With three interconnected chambers, students can model the interaction between
three different ecosystems. Choose the
traditional terrestrial, aquatic, and decomposition arrangement or create unique
biomes to model and measure. Decouple
the system for isolated investigations how does the availability of light affect the
ecosystem? Students can create two identical ecosystems and monitor one in light
conditions and one in dark.
The included cord efficiently ‘wicks’
water between the chambers.

Clean up is easy, and the chambers are durable
enough to use again and again. The unique
design of the PASCO EcoZone System allows you
to use your environmental science probes* to
actively measure a model ecosystem.

Monitor the physical environment!

Water potential is often preferred over
water content because it shows how water
will move in soil or from the soil to the plant.
The Soil Water Potential Probe measures the dielectric permittivity
of its ceramic disk to determine its water potential.

The Salinity Sensor measures the electric current through a solution between the two platinized platinum electrodes in the Salinity
Sensor Probe. The current through the solution is due to the movement of ions, so the higher the concentration of ions in the solution,
the higher its conductivity. A voltage (AC) is applied across the two
electrodes in the tip of the probe and the measured current is proportional to the conductivity of the solution.

Typical Applications:
A Explore the salinity of local water sources.
A Explore the interrelationship of salinity, temperature,
and conductivity.

A Measure the change in the salinity of saltwater as the
water evaporates.

Accessory Power Amplifier Increases Power to
1 A, ±10 V (See Page 56)

A Simple USB Connection to Computer

The 750 eliminates the need for a separate signal generator. In this LRC experiment, the 750 powers the circuit with a sinusoidal function and
using 3 voltage sensors, measures the voltages across the inductor, capacitor, and resistor simultaneously. In addition, it also records the output voltage and current. DataStudio can display all 5 traces on its oscilloscope so the phase shifts can be measured.

A New Sense and Control Feature
The 750 output voltage can now be controlled using the calculator in DataStudio.
For example, use the 750 output voltage to turn on a DC motor at a voltage
proportional to the light intensity reading on a Light Sensor.
New calculator functions included in DataStudio are:
Outputswitch (A)
Controls the ON/OFF state of the Signal Generator window when using a
ScienceWorkshop 750 interface. If the result of the sub-expression A is nonzero, then the Signal Generator is turned ON. Otherwise, the Signal Generator is
turned off. The waveform, amplitude or voltage settings of the Signal Generator
are unaffected by this command.
Outputvoltage (A)
Controls the voltage (DC) or amplitude (waveform) of the Signal Generator window when using a ScienceWorkshop 750 interface. The result of
the sub-expression A is used to set the output voltage or amplitude. Note: The parameter to output voltage will be limited to the range of +/-5V
(without a power amplifier), or +/-10V (with a power amplifier).
The 750 uses ScienceWorkshop sensors and cannot use PASPORT sensors.
