Surf's up! What causes the constant motion of Earth's oceans? Scholars discover the origins and types of waves in part nine of a 13-installment series. The resource illustrates wave behavior, their destructive power, and current research...

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...

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...

Physics class sure can have its ups and downs! The first in a series of seven interactives from the Waves and Sound series introduces young learners to the concept of wavelength. Scholars work through the interactive to discover the...

Have a seismic moment with your class as you show this animated video on earthquakes. Viewers find that quakes occur on faults and are caused by shifting of continental plates. They learn what properties are studied by seismologists and...

Continental drift happens over millions of years, but new perspective shows much faster changes. An informative resource offers a short term perspective using a series of satellite images. Viewers observe major changes to a coastline in...

In this AC waveforms worksheet, students answer ten questions about AC voltage, frequencies of waveforms and they interpret diagrams of AC voltage.

Consider this online interactive activity as a way to practice the names that often accompany human anatomy, such as the crown of the head and the roof of the mouth. Learners select an anatomy word with a double meaning from a drop-down...

In this waving flag worksheet, students listen to the song, fill in the missing words, complete a crossword and word search, and more. Students complete 5 activities.

In this causes of floods worksheet, students choose the best word from a word list in order to complete sentences about the causes of floods.

In this online electricity learning exercise, students are asked 10 questions about electric current and battery energy, an online answer key provided.

In this electromagnetism and electromagnetic induction worksheet, learners answer 11 questions using calculus to determine things such as magnetic flux and wave output.

In this electrical worksheet, students answer a series of  7 open-ended questions. Students explain the use of terms used in circuit board layout and manufacturing in order to answer the questions. This worksheet is printable and...

In this audio power amplifier worksheet, students answer five questions about class A amplifiers, sound pressure, crossover distortion, and amplifier design.

[Free Registration/Login Required] Move the points to change the frequency and amplitude of the waves while making the waves transverse or longitudinal according to the labels.

Students can observe the properties of a wave with different variables. Students can experiment with the type of end, damping factor, and tension in the string. Possible teacher lesson plans are included at the bottom of the page.

Conduct virtual experiments with water, sound, and light waves to determine the sine wave and patterns created in each.

In this simulation, two strings with different densities are held tautly as a wave pulses along them. Variables can be changed to alter the relative densities of the strings, as well as the type of wave pulse.
