A group of students have noted that the sidewalks on Temple Street have more cracks than
those located on Cambridge and Beacon Streets.
1.
Develop a hypothesis that might explain this observation and design an experimental
system to test this hypothesis.
Include the following in your design:
a) The type of measurements of sidewalk surface
b) How these measurements are to be made and documented
c) The number of measurements required for a significant evaluation
d) The types of samples (experimental systems) that will be measured
e) Which samples will serve as controls.
f) Which samples will serve as a model for your experimental system.
Make up some results and decide whether these results support or negate your
hypothesis? Why? (Justify your decision.)
Here's a helpful hint on how to report your data.
A typical graph representing the
relationship between dependent
and independent variables.
Number of Cracks-
Dependent Variable
Proposed Cause of Cracks-
Independent Variable
In order to establish cause and effect, the dependent and independent variables should be
correlated. If they are not correlated, then the independent variable is not the cause. If they are
correlated then the independent variable may be the cause. Further experimentation is always
necessary to establish causation especially in Biology.
