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.

BODY IMAGER - Miniature Human Body Temperature System infrared temperature measurement is used to restrict the spread of the deadly viruses for mass screening in public places such as airports, ports and terminals.
