Planning an experiment
	Poor 1 pts	Fair 2 pts	Good 3 pts
Defining the experiment	Poor - Independent variable briefly stated with no further variables explored. - No clear hypothesis stated.	Fair - Identified the independent variable, dependent and control variables. - No hypothesis	Good - Has clearly identified the independent, dependant and control variables, elaborating on how each affects the rate of photosynthesis. - Clearly stated hypothesis
Equipment	Poor - Briefly stated equipment to be used. - No diagram	Fair Identified some equipment to be used but lacking details eg. no mention of thermostatically controlled water bath for keeping water temperature constant - Drawn diagram but scarce annotations	Good - Selected suitable equipment: eg. 60 Watt bulb Table lamp Gas syringe etc. - Detailed and annotated diagram
Method	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. eg. How far away to place the lamp
Safety	Poor No details on safety	Fair Some vague mention of safety eg. use safety goggles	Good Safety issues clearly pointed out eg. Caution! Hot water bath Use gloves when dealing with sodium hydrogencarbonate
