Planning an experiment
	Poor 1 pts	Fair 2 pts	Good 3 pts
Variable Selection	Poor - Independent variable briefly stated with no further variables explored. Control not a true control	Fair - Identified the independent variable, dependent and control variables. Control was altered during experiment	Good - Has clearly identified the independent, dependent and control variables, elaborating on how each affects the rate of photosynthesis.
Hypothesis	Poor Hypothesis does not include all of the variables and is not clear what is being testest	Fair Light or Heat variables not appropriately identified as being tested.	Good Clear hypothesis of how light and temperature affect plant growth.
Procedure	Poor - Method stated without being in distinguished steps	Fair - Step by step method	Good - Step by step method, easy to follow and with sufficient detail.
Following Procedure	Poor Did not follow procedure at all.	Fair Occasionally followed procedure but could have been better.	Good Followed procedure exactly as it was followed.
Data Collection	Poor No data was collected or unclear or unorganized.	Fair Sufficient data but some missing or not correct data to ID which variable affects growth. Could be organized better or more clear.	Good Data collected daily. Shows distinct growth differences. Organized
