My goal is to ease the burdens of educators by offering memorable learning activities. Any noise source that is annoying, loud and potentially damaging to your ear can be considered noise pollution.

Ultimately, the magnets cause the paper plate to vibrate, which creates sound waves that travel to our ears. one easy price. Sound as a Longitudinal Wave. How is sound used to identify ecological hotspots? Activities are simplified explorations that can be used in the classroom or in informal learning environments.
