Students will use a variety of objects to participate in a partner activity and communicate using light and sound waves. Resources include a video, pictures and videos of the lesson in action, and examples of student work.

In this direct instruction lesson, 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 work.

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...

In this lesson, the young scholars will be experimenting to show how light shines in a straight line. They will also be experimenting to see how light reflects using mirrors. The students will be working in cooperative learning groups to...

If you're lucky enough to live in a place that gets snow in winter, you know that the feel of the snow can vary a lot. Sometimes it can be light and fluffy, and other times heavy and wet. This project shows you how to use data from daily...

This challenge is to build a dance pad that sounds a buzzer or flashes a light when you dance on it.

This lesson introduces the concepts of longitudinal and transverse waves. Learners 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...

A collection of video lectures created by University of Sheffield to excite young students about topics in physics in elementary school. The course covers topics like forces, gravity, magnets, sound, light, space travel, and the solar...

How do you recognize life on another planet? What tests do scientists use to determine if something is a life form when they are many light years away from being able to observe it directly? Try your hand at interactives to create a...

Light, bright, and cheerful, "The Four Seasons" by Antonio Vivaldi is some of the most familiar of all early 18th century music, featured in numerous films and television commercials. But what is its significance, and why does it sound...
