Understanding Waves

Using a stream table, erosion enthusiasts examine how the density of sediment and how the slope of land contribute to the amount moved by waves. You will not be able to use this entire resource as is; there are teachers' names and...

Light waves and sound waves are the focus of this science lesson designed for 5th graders. Besides discovering how these waves travel, learners also discover the basic properties of waves, and analyze data tables and graphs. The...

After learning about P waves and S waves, fifth graders view the intensity of earthquakes by examining seismographs and images of earthquake damage. Young scientists then forecasting future quakes by analyzing data about earthquakes...

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 high-intensity...

A fabulous presentation on light is here for you. In it, learners view slides which cover many important concepts of light. They understand exactly what light is, what the main sources of light are, what opaque, transparent, and...

A tremendous presentation on the properties of light. Young scientists are treated to slides which share a lot of fascinating information about light. This impressive PowerPoint is filled with great photos, graphics, and discussion...

Using a karaoke machine, a guitar, and other devices, learners explore the way sound waves travel. Using this hands on approach, learners can get a better understanding of wavelength, frequency, and more.

Students explore and learn about the concept of echolocation. In this echolocation instructional activity, students explore how animals and engineers use echolocation (seeing under water) and sound waves to look and hear things under the...

Learners use the internet to research how waves are formed. Using construction paper, they create a diorama in which they can see how waves are formed and end. To end the lesson, they also discuss the causes and effects of earthquakes...

Groups rotate through a series of stations and work with a partner to observe sound waves. Children describe sound in terms of pitch, volume, and frequency. To apply their new knowledge, the class considers how these observations can...
