STEAM Fair

During the 2014-2015 school year, a classroom parent, who is also a teacher with Science is Elementary, facilitated a scientific investigation about the size and shape of seeds in which students created paper copter models and measured the time it took them to fall to the ground from the same height. Students shared their findings at our yearly STEAM Fair.
