Let there be light. The last installment of a seven-part series has pupils conduct an experiment on light attenuation through different numbers of transparency sheets. They then relate the results back to how X-rays measure bone density.

In this mind-bending activity, young engineers explore this question of whether or not light actually bends. Using holographic diffraction gratings, groups design and build a spectrograph. The groups then move on research a problem...

Explore optics using an inquiry-based experimental approach! Young scholars use a set of materials to design and build a unit capable of focusing a beam of light. They experiment with different lenses to determine the best approach to...

Hop into a resource on Beer's Law. A PowerPoint presentation introduces Beer's law as part of calculating bone density from X-ray images in the sixth lesson in the series of seven. Individuals work on practice problems with this law and...

How can nanoparticles be used in the battle against skin cancer. Class members take on the question as they gather information about electromagnetic radiation, specifically ultraviolet radiation. Pupils learn about the mathematical...

Most of the twenty slides in this presentation include photographs or diagrams, making it an eye-catching way to teach about infrared telescopes. The pros and cons of using infrared light to study outer regions of space are explained....

Youngsters examine resource maps to find out which states are using solar and wind power and discuss as a class various other renewable energy sources. They use a provided data table to record pros and cons to each technology, build and...

For this physics worksheet, students design and build an electrical circuit using LED as a light source. They complete 2 short answer questions about their design.

Biotechnology pros produce their own biofuel using waste oil and fresh vegetable oil. They test the quality of their product using titration techniques and pH analysis. They write their observations and report their findings. Be aware...

Students investigate the law of reflection by using mirrors. In this physics instructional activity, students operate a robot using IR controllers. They explain the path of light as it reflects through a surface.

Students investigate how to read a topographical map and triangulate with just a map. They convert a compass measurement to a protractor measurement, reverse a bearing direction, and using a worksheet take a bearing of certain landmarks...

Learners explain the use of different technologies based on their resolving power. Explain how technologies are used to solve scientific and health-related problems. Explain the concept of using right tool for the job and develop a multi...

Students explore scientific observations by examining the parts of a microscope. In this optics lesson plan, students discuss the importance of a focal point and focal distance when utilizing an optical device such as a microscope....

A collection of video lectures from a course that explores the application of electrical engineering topics. Webpage includes twenty-eight lectures from a professor at the University of California, Berkeley. Lectures vary in length and...
