EDUCATIONAL GOALS
• Emphasis on use of technology within the context of accomplishing
authentic tasks.
• Students receive practice in selecting and using various technology
applications to accomplish a wide variety of tasks.
• Students use technology tools to enhance learning, increase
productivity, and promote creativity.
• Students use productivity tools to collaborate in constructing
technology-enhanced models, and produce other creative works.
• Students evaluate and select new information resources and
technological innovations based on specific tasks
• Students use technology tools to process data and report results.
• Students will conduct full-scale scientific investigations: formulate the
questions to be answered, design approaches which incorporate
appropriate variables and controls, implement solutions, collect and
record qualitative and quantitative data, and communicate the results.
• Illinois Learning Standards, State Goal 11 will be accomplished:
“Have a working knowledge of the processes of scientific inquiry and
technological design to investigate questions, conduct experiments,
and solve problems”
CURRICULUM CONCEPT OUTLINE
– Students will design and build an experimental set-up to
solve a problem, develop an experimental procedure, and
collaborate with others to make modifications.
– Students will collect and analyze data, make conclusions
supported by the data, and continuously discuss and reflect
about the important aspects of doing scientific inquiry.
– Students will write laboratory reports containing following
points: Purpose, Theory, Pre-lab Questions, Equipment
And Materials, Procedure, Safety, Combined Data (
Results, Observation Table, Calculations ), Post-lab
Question, Data Analysis & Discussion, and Conclusions
– Students will present and defend their experimental set-up,
data, and conclusions using Microsoft power point.
Introducing Interactive Technology with use of
Pasco Educational Software And Hardware
Interfaces
• Pasco Scientific is the leader in the bringing interactive
technology into the classroom.
• Pasco Scientific is the leader in the development of data
collection tools and software for science and math educators.
• Pasco is a leading developer of innovative, technology-based
science learning solutions that enable teachers to improve
science literacy by engaging students in hands-on science
exploration.
• Pasco enables electronic measurement through probeware and
sensors, electronic data collection through dataloggers and
data analysis through software applications.
• The new Xplorer GLX captures, analyzes, annotates, stores
and prints data quickly and seamlessly, without being
connected to a computer.
Representative Activities
• Pasco and Vernier equipment will be utilized by
students while they will work in the area of infrared,
visible and ultraviolet radiation.
• In IR they perform measurements of black body
radiance, measurement solar radiance and simulate a
non-contact temperature sensor.
• With use of light sensor students will compare light
intensity vs. distance, study of interference, diffraction,
polarization, and measure relative light intensities in
daylight.
• With the ultra violet sensor students will conduct a sky
survey of UV light, investigate effectiveness of UV
protection from sunglasses, windows or sunscreen
lotions.
PASPORT INFRARED LIGHT SENSOR
PS-2148
$199.00
The Infrared sensor uses a Nitrogen filled Thermopile with a Tallium BromideIodide window to sense wavelengths from 580 to 40,000 nm. This allows students to
measure a variety of phenomena including the infrared radiation emitted from
their own hand.
Typical Applications:
 Measure black body radiance
 Perform Leslie's Cube experiments
 Measure Solar radiance
 Evaluate heat flow into or out of the
sensor
 Simulate a non-contact temperature
sensor
PASPORT LIGHT SENSOR
PS-2106
Measure bright sunlight to dim candlelight,
and everything in between! Light Sensor has
three ranges to accommodate a wide variety
of student light measurements. Switch ranges
with the touch of a button and without losing
calibration.
Typical Applications:
Compare light intensity vs. distance
Study interference/diffraction/polarization
$59.00
Measure relative light intensities
in daylight
Monitor a solar eclipse
PASPORT UVA LIGHT SENSOR
PS-2149
$159.00
The Ultra Violet Light Sensor employs a
narrow pass filter to measure the UVA
band of the spectrum (315 to 400 nm).
Typical Applications:
 Do your sunglasses really protect you?
 Conduct a sky survey of UV light.
 Investigate effectiveness of UV protection from sunglasses, windows or sunscreen
lotions.
PASPORT GENERAL SCIENCE SENSOR
PS-2168

light, sound level and
voltage. Great for a
variety of general
science explorations.
Includes: Stainless Steel
Temperature Probe,
Voltage Probe, 3 light

PASPORT SOUND LEVEL SENSOR
PS-2109
Sound level and noise pollution are
key measurements in science.
Sound Level Sensor gives true
sound level measurements with both
dBA and dBC scales. Three switchselectable ranges (from 30 dB to 110
dB) allow for greater functionality
and flexibility. Measures both
sound level and sound intensity.
Typical Applications:
Explore sound levels inside and
outside of the classroom
Discover the logarithmic
relationship between sound level
and sound intensity
$99.00
Range:
Sound Level
30 dB - 70 dB
50 dB - 90 dB
70 dB - 110 dB
Intensity
10-3 µW/m2 - 10 µW/m2
1 µW/m2 - 1000 µW/m2
10 µW/m2 - 10,000
WAVEPORT SOFTWARE, SINGLE USER
CI-6872D
Students will have the opportunity
to learn about waves and sound in
an interactive manner.
WAVEPORT engages students'
senses, allowing them to see, hear
and feel sound waves.
WAVEPORT software uses only
the internal sound capability of the
computer, so no additional
equipment is necessary.
WAVEPORT also enables students
to collect and analyze sound waves.
Using an external sound source or a
favorite music CD, students can see
the changes in the sound waves as
they change the input sound.
Students can whistle into the
computer microphone and observe
the waveform on the screen. Next,
they can change the pitch of their
whistle and see the changes in the
waveform.
$59.00
WAVEPORT allows students to
directly manipulate a waveform
to see, feel, and hear the effects of
their manipulations. Students can
change the frequency of the
waveform by dragging an
intuitive icon across the screen.
As students change the frequency,
they can hear the changing sound
waves from the computer's
speakers!
