Sink or Float
Grade ones discover why some items sink or float
Equipped with a variety of items, including foil, a sponge and a coin, grade ones predicted and tested which articles would stay afloat.
The science experiment explored the density of different weighted materials, and their overall characteristics, including physical makeup (i.e., made of metal, wood, etc.).
This allowed students to use scientific thinking, like predictions, observations, comparison, experimentation and evaluation.
