What to do DIVIDE the class into groups of four students with
the following roles: Class GOES outside to a field of grass.
Equipment Handlers PLACE the dowel square where the group wants
to work. Group members each COUNT the grass blades inside a
section of the square. Recorders WRITE the number of blades each
student counts on the data collection sheet. Equipment Handlers
WALK the square along each side of the field to determine its
length and width. Recorders WRITE the length and width of the
field on the data collection sheet. Speakers FILL OUT the data
collection sheet to determine the total number of blades of
grass in the field. SPEAKERS report their results to the class.
COMPARE each group's results. We used this method at the Miami
Museum of Science. Our field is about 3,600 square meters and
there were about 1,300,000 blades of St. Augustine grass. What's
