In this direct instruction lesson plan, students draw sketches in their science notebooks in order to make sense of wave properties. Resources include a slideshow presentation on the properties of waves and multiple examples of student...

[Free Registration/Login may be required to access all resource tools.] Students investigate and analyze characteristics of waves, including velocity, and calculate the relationship between wave speed, frequency, and wavelength.

All waves will reflect and refract in the right circumstances. The reflection and refraction of light explain how people see images, color and even optical illusions. This tutorial discusses each concept and presents an experiment to try...

This lesson introduces the concepts of longitudinal and transverse waves. Students see several demonstrations of waves and characterize them by transverse and longitudinal behavior. This lesson also introduces the Sunken Treasure theme...

This site from the National Aeornautics and Space Administration provides a fun activity for the subject. "Clouds often hide large areas of the Earth's surface. We can use radar to make detailed maps of Earth right through clouds or...
