How to answer EOC questions.

 This question involves knowledge of:  Controlled variables.

 This question involves knowledge of:  Manipulated variable

 This question involves knowledge of:  Responding variable

 Did you incorporate supporting data? (numbers)  Did you use inferential logic?  Example: As the amount of CO2 increases, the mass of the plant increases. When plants were grown without CO2, there was no increase in mass. However, when plants were grown with 1400 ppm CO2, the plant mass increased to 10.8 grams. The bean plants had 10 grams more mass when the CO2 was highest.

 This question involves knowledge of:  Ensuring validity

 This question involves knowledge of:  Predict logically what might occur if the investigation changes.

1. Electrical energy to heat energy 2. Light energy to chemical energy 3. Light energy to heat energy 4. Heat energy to heat energy 5. Heat energy to kinetic energy 6. Kinetic energy to kinetic energy 1. In the grow lamps 2. In the plants 3. In the plants 4. From lamp to air or from water to the air 5. From lamp to molecules in the air 6. From molecules of air to molecules of water BEFORE/AFTER ENERGY WHERE

 This question involves knowledge of:  Identify how organisms use matter to sustain life.

 This question involves knowledge of:  Identify how DNA provides instructions for assembling proteins.

 This question involves knowledge of:  Identify how organisms pass on genetic information.

 This question involves knowledge of:  Identify how organisms use matter to sustain life.

 The prediction portion of the hypothesis must answer the given question including the effect of the manipulated variable (amount of mineral nutrients) on the responding variable (height of bean plants).

 A hypothesis must give a cause-effect reason for the prediction (…because bean plants use mineral nutrients to make food for growth).

 A list of the minimum materials needed to perform the procedure (e.g. bean plants or bean seeds, ruler, mineral nutrients, growth chamber or pots with soil)

 At least 2 controlled variables (e.g. nutrient type, ruler, lights, initial plant size).  Only 1 manipulated variable (amount of mineral nutrients)

 A responding variable (height of bean plants)  Procedure states or implies measurements are recorded periodically.  Are trials repeated?

 Your procedure should include a validity measure not included in the scenario investigation. (e.g. more controlled variables, better measuring technique, increased range of conditions, control for sample bias).  Logical Steps – able to repeat the procedure effectively?
