Young scientists explore hearing through multiple experiments, demonstrations, and activities. They focus on the changes in hearing over a lifetime, how we can determine where a sound is coming from, and the ability to filter noises.

Students investigate their hearing range. They participate in a week-long hearing experiment, listening for various sounds during recess time, and determining which noises were easier or more difficult to hear.

For this scientific methods worksheet, students will study a graph comparing the hearing range of humans to the range of sounds elephants make. Based on this graph, students will complete 3 short answer questions.
