Students explore the light spectrum. The teacher uses holographic diffraction grafting film on an overhead to demonstrate the true nature of color. After observing a vivid rainbow, students recognize that white light is composed of all...

The electromagnetic spectrum includes everything from very powerful gamma rays (which are used to treat cancer) to much weaker radio waves (which include microwaves). Through a hands-on activity, scholars explore the temperature...

In this light instructional activity, learners describe the electromagnetic spectrum based on wavelength and frequency. Students determine the wavelength, frequency, and energy for given point on the spectrum. This instructional activity...

Using a Maori legend, How Maui Tamed the Sun, youngsters are introduced to the importance of sunlight to civilization. Teach them about nuclear fusion that occurs to produce the solar energy we later receive on Earth as...

Youngsters investigate autism and autism spectrum disorders. They access a variety of websites which present information on ASD's, and assess how accurate the information they've read actually is. They work in groups and utilize...

High schoolers investigate the symptoms of autism spectrum disorders, and compare expected child development with development that may indicate a diagnosis of these disorders. The final project for the lesson is the creation of posters...

Take the class over the rainbow. Pairs or small groups follow directions to create a spectrograph. The pupils measure the angles formed by the different colors of the spectrum along with calculating the lengths formed by the spectrum and...

Take a look with another perspective. Pupils read to find out what portion of the electromagnetic spectrum a space telescope sees and the difficulties of viewing infrared radiation from other objects in space. Individuals discover how...

Elements don't have fingers, but they have fingerprints! An interactive simulation gives young scientists the opportunity to study orbital changes of an atom and the corresponding spectrum reading. They realize how each atom has a...

Stars are too hot to visit, so how do we know what different stars are made of? An enlightening simulation uses a spectrum graph to show the various electron emission and absorption reactions. Scholars experiment with both helium and...

Students explore both the scientifc world of the light spectrum and the research world of the library and/or internet in this activity, which asks a question about the light spectrum to be answered with student research. There is a space...

In this bellwork on the electromagnetic spectrum and planets worksheet, students answer questions about the information determined using a spectroscope, the geocentric and heliocentric models of planet rotation and the planets.

Has the occurrence of autism increased over the years, or do the changes in diagnostic criteria account for the difference? High schoolers read an article about autism spectrum disorders and the related epidemiological studies that have...

Electromagnetic waves travel though empty space, something no other wave type can accomplish. Young scientists learn more about the entire spectrum of electromagnetic waves. They sort cards and apply their knowledge to create models of...

The University of Hawaii has published a vast collection of midterm and final exams for their Physics 152 course. This particular exam offers a variety of assessment methods, and covers the topic of electromagnetic radiation....

Let there be light in your classroom with a video that explains that light travels in waves, the electromagnetic spectrum contains seven colors, and the color of an object depends on which light waves it reflects and absorbs. With...

In this proton NMR spectrum learning exercise, students indicate the number of signals in the proton NMR spectrum for compounds and give the structure of the compound and assign the NMR peaks based on given data. This learning exercise...

Students examine the electromagnetic spectrum and demonstrate the elements within.  In this investigative lesson students complete a demonstration and calculate the energy of a photon. 

In this light spectrum worksheet, students will read a diagram and a chart listing information about the different types of light rays from Gamma rays to radio waves. Then students will write a short essay about a new life-form that...

Students investigate the electromagnetic spectrum, focusing on visible light. They are introduced to the idea that all light travels as waves, and that wavelength defines the various regions of the electromagnetic spectrum.

Young scholars explore the nature of electromagnetic spectrum through a series of experiments. In this physics lesson, students determine how light behaves under certain circumstances. They explain how humans perceive colors.

Students explore the infrared radiation and the part of the spectrum that is not always visible.  In this electromagnetic instructional activity students complete a lab activity on the different wavelengths.

Students explain what is meant by term nuclear radiation, describe in detail electromagnetic spectrum, differentiate between ionizing and non-ionizing radiation, understand half-life of isotopes, differentiate between processes of...

Students discuss the light spectrum and light waves as well as how the properties of light and color have contributed to important discoveries about properties of the universe. They research the term redshift and the redshift phenomenon...
