Vibrating objects make sound! Manipulate items by plucking, striking, shaking, or rubbing them together to hear the sounds they make. A tuning fork, crystal goblets, and an oscilloscope are among the tools that we use to investigate sound.

SUPPORTS MINNESOTA STATE STANDARDS:
Nature of Science and Engineering
Use observations to develop an accurate description of a natural phenomenon and compare one's observations and descriptions with those of others.
When asked 'How do you know?', students support their answer with observations.
Recognize that describing things as accurately as possible is important in science because it enables people to compare their observations with those of others.
Recognize that tools are used by people, including scientists and engineers to gather information and solve problems.
Raise questions about the natural world and seek answers by making careful observations, noting what happens when you interact with an object, and sharing the answers with others.
