Science Code Detectives :)

Students were put into groups of 4 and asked to develop a code by assigning letters of the alphabet to a selection of objects. Using this sound code, the students sent messages to one another by dropping a series of objects into the drop chamber.

The target of the lesson was for the boys and girls to recognize that the properties of sound can be used to make a code and communicate different bits of information. They learned that the more they could discriminate between sounds, the easier it was to determine what letter was being made and vice versa. For instance, 2 metal objects may sound very similar and it would be challenging to figure out which letter was being represented.
