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

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

Hypothesis: ________________________________________(testablestatement determined after initial background research using referencematerials) e.g. The density of microscopic algae is greater in stagnantwaters than in the rapids; headwaters have fewer microscopic algae than themiddle 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 isbeing 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)

Conclusion:__________________________________________
