The students each run for 10 second., measure the distance, and record
the results. In cooperative groups the students find the mode, median,
mean, and range for the groups distance ran in 10 seconds.
The distances run by each student are collected and recorded on a whole
class chart. Cooperative groups develop a graph using the data. The
graph must include title, correctly labeled information, and at least
A = Bug Size
B = Distance traveled by the bug in 10 seconds
C= Bug body lengths traveled
D= Student Height
E= Distance traveled by student in 10 seconds
F= Student body lengths traveled
G= Distance bug would
travel if it were the same size as the student.
Record your data
B ÷ A = C
E ÷ D = F
D x C = G
