With the STC™ Sound unit, students learn characteristics of sound, variables that affect it, and how it is transmitted and received. The concept that sounds are vibrations and that vibrations cause sounds is reinforced through activities as students investigate pitch and loudness, observe transmission of sound through different materials, and examine how distance affects sound.
Unit Kit comes with a Teacher's Guide, a Teacher's Tools CD, 15 reusable Student Investigations books, 8 copies of STC BOOK: Sounds, and the materials needed for a class of 30. Added Value: 8 KIDS DISCOVER Nonfiction readers. Refurbishment Set replenishes all kit consumables.
The Two-Use Kit comes with all of the great materials you'd expect from the STC Program™ along with a box containing the materials for a second, non-concurrent use. All you need to do is set the box aside until you are ready for it.
