In this unit, students start by observing a perplexing phenomenon. When a sewing needle taped to a cone is dragged over the surface of a plastic disc that is spun underneath it, it produces voices and musical notes. This leads students to start wondering about other sound-related phenomena, which in turn leads to wealth of new questions about 1) What causes different sounds? 2) What is traveling from a sound source to our ears? 3) How do we hear and why do we hear things differently in different places? and 4) How do electronic devices (digital sound sources) produce and detect sounds?
This first-grade unit on light starts with students exploring how many shapes they can see on different pieces of paper at various locations around their classroom when the lights are turned off. They are surprised to find that some of the shapes are not visible in these conditions. This leads students to start wondering about other phenomena related to seeing in the dark, which in turn leads to new questions and design problems related to how they can make their room completely dark.
