Description:
Students will take apart a store-bought speaker to see its hidden parts and then build their own working version from scratch.
Purpose:
They will discover that sound is created by physical vibrations. By using a magnet and a coil of wire, they will see how "invisible forces" can push a speaker cone to make music without anything actually touching it.
DOK Level (The Goal): They will move from just naming parts to explaining the science. They will create models to show cause-and-effect and write their own scientific questions to investigate throughout the unit.
