Students examine the basics of luminous efficacy and why it is used.  In this light source lesson students test energy efficiency and the luminous efficiency for babies.

Young scholars are able to demonstrate knowledge of natural and artifical satellites. They are able to demonstrate the differeence between "active" and "passive" communciation. Students are able to define radio waves, amplification...

Here are some instructions for leading learners through a hands-on activity for investigating ultraviolet radiation. First, introduce them to light and refraction. Then introduce them to the electromagnetic spectrum. Finally, give...

Here is a physical science activity where pupils place thermometers inside of a white and a black paper pocket and place them under a lamp. They record and compare the temperature increase over a ten-minute period. Have your class...

Pupils examine blackbody radiation and light wavelengths. Students research the various types of electromagnetic spectrum. Pupils examine any misconceptions they may have in light.

Using spectroscopes, high school astronomy, physics, or chemistry learners observe emission spectra from several different sources. This stellar NASA-produced lesson plan provides terrific teacher's notes and a student handout. Make sure...

Astronomers practice downloading data from a high-energy satellite and translate the data into colored or shaded pixels. As a hands-on activity, they use pennies to simulate high-energy satellite data and they convert their penny...

Students investigate the history of astronomy and how the study of constellations has evolved since the dawn of ancient civilization. They conduct research using a variety of resources. The teacher uses demonstrations to model how the...

High schoolers identify and explain how various inventions and astronomers have improved our appreciation of the universe. Students identify at least two constellations in the sky and discuss how they were used in ancient times to tell...

Students study the history of the light bulb and how an incandescent light bulb works.  In this electricity lesson students complete several experiments on the light bulb.

In this honor chemistry I worksheet, students use all available resources to answer each question given. Students apply their knowledge of light, quantum theory of light, Bohr's model, photoelectric theory.

For this medical fields worksheet, students study the different studies of medicine. Students match 11 terms to the correct definition that is provided.

Though this is meant to be second in a two-part lesson, the two are not dependent on each other. Pupils play the roles of visible light rays, light or dark surfaces, and carbon dioxide molecules. They interact and react according to...

First graders identify the sun as a source of heat and light. They identify features of houses that help keep use sheltered and comfortable throughout daily and seasonal cycles. Students are told that summer is the best season to...

Students discuss the concept of global warming and view a multimedia clip on the global warming phenomenon. They statistically analyze mean temperature data and compare a given set of data. Data on atmospheric CO2 is done then they...

In this stars worksheet, students review what makes up a star, how astronomers learn about stars, and the different types of stars including low mass and high mass stars. This worksheet has 62 fill in the blank statements.

Pupils learn the procedure for mixing secondary colors from primary pigments and observe the results of mixing two primary colors.

Students complete a unit on orbiting spacecraft designed to study astronomical objects. They conduct Internet research on NASA missions, use a satellite dish to downlink information, and construct and launch a rocket out of paper and tape.

Learners perform a simulation of the workings of an electron microscope to discover that the resolution will need to improved to detect objects in the nano-scale. They use wooden dowels as detectors to determine the shape of objects in...

Pupils observe and explore the characteristics of light.

Ninth graders examine how dark surfaces absorb more light than light surfaces. They perform an experiment that compares various surfaces abilities to absorb heat, then record and analyze the results.

Young scholars become aware of some of the objects studied in, and concepts associated with, high-energy astronomy. They do this by participating in card games that teach and review these concepts.

This page defines electromagnetic radiation. Included are links to more information.

Visible light waves are the only electromagnetic waves we can see. We see these waves as the colors of the rainbow. Each color has a different wavelength. Red has the longest wavelength and violet has the shortest wavelength. When all...
