Uncover the science behind the beautiful phenomena of rainbows with a simple demonstration. Shine light through different-sized containers of water as young scientists learn that rainbows occur when visible light is split up into its...

Scholars use springs to explore waves and their characteristics. Using data, learners formulate a math problem to investigate velocity, wavelength, and frequency. They will use that same formula to explain examples in nature.

Young seismologists learn more about plate tectonics with a set of pre-lab, lab, and post-lab lessons plans on earthquakes. After exploring how waves travel through various materials, sixth graders record their observations and...

Introduce third graders to energy waves with a hands-on geology activity, in which they answer questions and compare seismograms in the San Francisco Bay area. After a demonstration that shows how bigger waves indicate a...

By measuring the wavelength, frequency, and intensity of electromagnetic radiation, scientists determine the temperature, density, and composition of far away items. Scholars rotate through ten lab stations using a spectroscope at each...

Students investigate why the sky is blue and the sunset is red. They are asked why do you think that we see the sky as blue? Students write a hypothesis on their "Blue Sky Lab Sheet". They explain why they think that the sky is blue...

If the delay between a sound and its echo is less than 1/10th of a second, the human ear can’t distinguish it. Through the use of a Slinky, rubber band guitar, and straws, scholars explore where sound comes from and how it travels....

Young scholars define electromagnetic radiation, list major categories and uses of electromagnetic waves, identify potential health risks with electromagnetic waves, and demonstrate understanding of Plank's constant by solving...

Fifth graders examine electromagnetic wave spectrum. In this science lesson, 5th graders discuss the aspects of the electromagnetic wave spectrum and complete a worksheet identifying the parts of the spectrum.

Ninth graders explain waves in terms of energy transfer and describe their basic types and characteristics. They solve mathematical problems involving wavelength and frequency. Students conduct experiments in reflection and refraction.

Students describe what scientists mean by an "expanding universe" in their own words. They explain how scientists comprehend the universie is expanding. Students comprehend the vast scale of the universe. They comprehend how theory...

Students discuss sound and how it's measured, and through experimentation and implementation of the scientific method, they determine the speed of sound.

Pupils examine how the regions of the Sun are studied using spectroscopy. They investigate the electromagnetic spectrum and the types of radiation that are associated with it. They use prisms and CD's to examine the light spectrum. They...
