Dust Catchers

Author(s): Nancy Moreno, PhD, Barbara Tharp, MS, and Judith Dresden, MS.

Class Bar Graph

Conduct a brief survey of the values that students obtained for their dust counts. Then, create a chart on the board, similar to the one pictured on this to accommodate the range of counts reported by the students. Label the x-axis “number of particles” and the y-axis “number of rooms.” 

Have each student label a sticky note with the type of room that he or she tested, and then place the sticky note on the appropriate place on the graph.
