The forthcoming STEM Central context on Sound for early years to fourth level offers opportunities to explore the speed of sound through different substances. But what do these speeds mean to learners and how do they compare to speeds with which they might be more familiar? Capitalising on the 2012 Olympics which draws to a close this evening, why not relate it to the speed of athletes they may have seen on TV this summer? This interactive from the New York Times “One Race, Every Medallist Ever” may be of use in making this connection.
