The students will create a communication device using everyday resources. The students will explain how vibration is used to create sound and sound waves.
This lesson results from a collaboration between the Alabama State Department of Education and ASTA.
Primary Learning Objective(s):
I can construct a model that uses sound.
Additional Learning Objective(s):
31 to 60 Minutes
Materials and Resources:
Tool Kit (1 kit per each group of two students):
chart paper, sentence strips
Technology Resources Needed:
The teacher should know that speaking into a cup will create sound waves, which are converted into vibrations at the bottom of the cup. The vibrations travel along the string and are converted back into sound waves at the other end so your friend can hear what you said. Sound travels through the air, but it travels even better through solids such as your cup and string, allowing you to hear sounds that might be too far away when traveling through the air.
