Students compare and contrast the properties of salt water in the oceans/seas and freshwater elsewhere on the planet. They also analyze mixing caused by currents in the ocean, including the effects of warm and cold water as well as with...

Learners explore the different properties of waves. In this physics lesson, students differentiate mechanical and electromagnetic waves. They explore each lab station and write their observation about the wave behavior they see.

Students perform 3 hands-on activities to help them explain the terms "crest" and "trough" as related to sound, water, and light waves. All three waves types have troughs and crests. The activities use toys to demonstrate the properties...

What's life like aboard an ocean exploration vessel? Junior oceanographers examine the important role of communication in ocean research in lesson two of a five-part series from NOAA. The materials introduce the class to life on...

Students participate in a problem-solving activity, that includes Internet research, about how energies such as currents, waves, tides, etc. affect the ocean.

In this light spectrum learning exercise, learners 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...

Students experiment with objects of different densities. For this density lesson, students examine same-sized objects with different weights, then look at a teacher explanation of density. Students make wave bottles and a density jar...

Students demonstrate the motion of waves. In this wave lesson, students demonstrate the various attributes to waves and the properties through a variety of hands-on activities.

Eleventh graders explore the wave and particle properties of light.

Students discover the differences between P- and S-waves using a slinky. They see that when displacement occurs along a fault, the built up strain of energy is released in the form of seismic waves.

Ninth graders identify the different parts of a wave. In this physics lesson, 9th graders observe wave behavior as it travels through a boundary. They determine the relationship between wavelength, frequency and velocity.

Learners discover the properties of waves in Chemistry and Physics. In groups, they develop and build their own device to demonstrate transverse waves. They complete their tests, record the results and discuss the conclusions with the...

Have your class engage in lessons on earthquakes. Learners explore the science behind earthquakes using interactive websites and video clips. Then, they review the layers and parts of the Earth before delving into the causes of...

Breakwaters offer marinas and beaches protection from large ocean waves, but how do they work? Scholars observe wave patterns and wave amplitude during the simulation. They control the number of openings, width of openings, distance...

Build a spectrometer to analyze properties of light. Scholars examine the spectrum from CDs and DVDs from two different light sources. Using the spectrum, they work to identify different elements.

Beat the summer heat by exploring the properties of color. Scientists view a video explaining the relationship between light absorption and energy transfer using variables including intensity, time, and wavelength. A multiple-choice...

Students investigate the refraction properties of gelatin to calculate its index of refraction. They discover that as the light travels through the gelatin, its speed and wavelength also change. Students find th indes of refraction of an...

Since light travels faster than sound, some people may appear bright until you hear them speak. The presentation covers what sound is, how fast it travels in various mediums, properties of sound, hearing, and the parts of the human...

Ninth graders conduct research on the subject of sea water. They use a variety of resources to obtain information. There are helpful resource links listed in the lesson. In conjunction with the research students make inquiry of the...

Students explore hearing loss caused by sound waves. In this physical science lesson plan, students will start by learning about waves and wave characteristics and move into sound waves. Students will study how sound effects their...

Learners explore the concepts of light waves and sound waves. In this physics lesson plan, students complete activities that require them to investigate how light and sound waves travel.

Eighth graders investigate the acoustic properties of materials in order to develop soundproofing products.  In this soundproofing lesson students research different resources, design and perform experiments and fabricate, test and...

Seventh graders explore stars. In this star lesson, 7th graders apply generalities about space objects to constellations and explore the differences between radio waves and light waves by answering essential questions in their research.

Students explore how sound waves move through liquids, solids and gases in a series of simple sound energy experiments. They describe how sound needs molecules to move and that changing the medium that it travels through changes the...
