A colorful and comprehensive PowerPoint highlights this lesson on waves. Junior geophysicists pretend that they are hired to analyze seismic waves. A worksheet is provided to go along with an online article about how compact discs work...

Do radio waves create light? It's more difficult to understand the things we can't see than those that we can. The simulation compares the relatively small range of visible light to the entire electromagnetic spectrum. It graphs the size...

Three main factors determine the wave height experienced in the ocean. Scholars use a virtual simulator to alter wind speed, fetch, and duration. Each combination creates a unique wave measured in significant height.

If you are at a sports match and the crowd starts two waves that are both headed toward you at the same time, what do you do? The simulation applies the concepts of constructive interference and destructive interference to that very...

Does the depth of a pond matter to the waves created when rain is falling? Many people assume the answer is no, but interestingly, it does matter. Pupils explore this concept and other variables related to wave behavior through a...

How can a pan flute sound one note while we hear a chord? The simulation explores sound waves, vibrations, and harmonics at the molecular level. Scholars control the pipe into which air is being blown, the length of the pipe, and which...

Don't string your class along! Physics scholars discover the fascinating forces behind the music of stringed instruments using an interactive. From a series covering sounds and waves, the interactive asks users to identify nodes and...

Ever wonder what really goes on inside a clarinet? Show your young scientists the physics of open-end air columns through an easy-to-use interactive. Learners examine the features of standing waves and calculate frequency and length in a...

Learners identify the different parts of a wave. In this physics lesson, students explain how animals communicate using sound waves. They discuss the effect of Navy's sonar on dolphins and whales.

Radio waves are all around us! How do they transmit sound? Using an interactive, scholars examine how songs travel through the air. The resource explains the process from the radio station, to signal towers, to the radio unit. A look at...

It's an ocean rescue mission! Groups must find a pilot downed off the coast of the Chesapeake Bay. Rescuers must determine the distance needed to travel as well as the heading to get to the pilot's last known position. Taking...

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...

Boat ramps move with waves and changes in water level. Scholars decide on the proper length for a ramp so the angle connecting both sides is appropriate. They visualize the situation and use a simulation to view the results with their...

What happens to radio waves, time, and light in and near a black hole? Young scientists explore what is known about observing frequency and time at various distances from a black hole. They control the size of the black hole and the...

Young scholars describe how wedge and lever makes work easier. In this physics lesson, students analyze experimental data by creating a graph to see the trends. They calculate the work done and mechanical advantage of these simple machines.

What is the fastest way to get from point A to point B if you are going through two different mediums, such as air then water? Scholars explore the way light travels through air, water, acrylic, glass, and diamond as they answer this...

What determines which ball rolls the fastest — the weight, the radius, the material, or something else? Scholars select two balls to race down the inclined plane, determining their material and radius. As they race, the simulation graphs...

During the Battle of Baltimore in the War of 1812, only 25% of the bombs and rockets fired at Fort McHenry actually reached their target. Using an interactive online simulation, combine your historical study with physics and...

Electricity travels at the speed of light, 186,000 miles per second. Through a simulation, classes see how the structure of energy bands in crystals of atoms determines how materials conduct electricity. Participants can change the...

Students model the flow of electrons in a circuit, draw diagrams of an electric circuit and build an electric circuit. Students explain how to tell when the path of an electric circuit is complete, and test the conductivity of a variety...

Students simulate the development of an underwater amusement park after reading background on Coral Reef State Park. They decide which factors they would need to consider such as the ocean floor, currents, wave patterns and water...

Students participate in an instant activity as they enter the gym. They work with a parachute, moving it using different motions. They use their wrists, to move the parachute while moving in a circle, and play a game of Cat and Mouse...

Students play a game of tag to explain pathogens in their bodies.

Students use different parachute activities to study weather and land patterns and formations. Tornados and hurricanes can be discussed as students make large waves (move from very high to very low) that mimmick these two weather...
