Helping children relate to the topics they study is what the Real World Science series of videos does best. Real World Science: Sound helps students learn the principles of sound, the range of human hearing and significant terms, as they discover the science behind every day sounds. Students will also travel deep into the ocean and high into the skies in search of creatures that use echolocation.
