Ignite students curiosity in wave movement via this interactive relay race activity. Students will explore the change in speed of sound and light waves as they pass through media. The students will work in large groups and arrange students in different formation to mimic the arrangement of particles in solids, liquids, and gases. They will have the "wave" in the form of another student move through the medium.
While engaged in the relay race, students will be challenged to record data and use the data to derive the relationship between wave type and speed through media. They will be able to conclude that light slows down as the density of the media's particles increases (ie. light moves faster through gases than solids) and that sound has the inverse relationship.
