Scientific Instrument Collection: Exploring Acoustics

1 Favorite 0 Copies
Engineering, Technology, and Applications of Science +2 Age Level Elementary (9 to 12 years old)

This collection includes videos demonstrating key principles of the science of sound, using some of the Smithsonian's scientific instrument collection. These videos are paired with the Visible Thinking Routine, "What's going on? What do you see (or hear) that makes you say that?" as a way to check for understanding. Learners can select one or more of the videos to watch and then provide their interpretation of what's happening and support it with a justification from the video. Learners can also explore additional short experiments, under the heading "Additional Resources" to further understand these principles in action.  #SmithsonianMusic
