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 Bromide-Iodide 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 $59.00 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

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 $139.00 Simultaneously measure temperature, light, sound level and voltage. Great for a variety of general science explorations. Includes: Stainless Steel Temperature Probe, Voltage Probe, 3 light ranges: 0 to 100; 0 to 10,000; 0 to 150,000 Lux. Sound Level: 50 to 100 dbA.

PASPORT SOUND LEVEL SENSOR PS-2109 $99.00

Range: Sound Level Intensity

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 switch-selectable 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

30 dB - 70 dB 50 dB - 90 dB 70 dB - 110 dB

10-3 µW/m2 - 10 µW/m2

1 µW/m2 - 1000 µW/m2

10 µW/m2 - 10,000

WAVEPORT SOFTWARE, SINGLE USER CI-6872D $59.00 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.

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!
