Fifth grade students in Donald Logue’s science class at F. K. Sweet Elementary School recently completed an investigation to determine which objects would create the biggest impact crater when dropped from a height of one meter. Students used two different types of marbles and one piece of sandstone as their variables. Students first found the mass, then the volume, and finally the density of the objects to use as a basis for their hypothesis. Then students measured the width and depth of each crater and found the average size after three trials of each object. Pictured, from left, are Nate Baker, Justice Anderson, and Lance Fleschner.
