Problem Area:
(group focus areas: plants, microorganisms, etc.)

Questions:
(how or why questions may be answered through scientific investigation) e.g. How does the rate of water flow affect the number of microscopic algae found in the water?

Hypothesis:
(testable statement determined after initial background research using reference materials) e.g. The density of microscopic algae is greater in stagnant waters than in the rapids; headwaters have fewer microscopic algae than the middle and lower reaches.

Experimental Design:

Independent variable
(what is being measured) e.g. number of microscopic algae per cm2

Dependent variable
(the effect of which is being tested) e.g. rate of water flow

Controlled variables
(same river; same day; same sampling method; same sample size; same observation method)

Data Generated:

Sample size: Unit of measurement:

Design of table and/or graph: (draw below)
