Explanation:

To answer these parts, we need to assume a specific experiment (e.g., an experiment on plant growth with different fertilizers). Here's how to approach each part:

Part E: Conducting the Investigation (with Independent and Dependent Variables)

Answer:

To conduct the investigation (using a plant growth experiment as an example):

1. Independent Variable (IV): The type of fertilizer (e.g., organic, synthetic, or no fertilizer as a control). This is the variable we manipulate.
2. Dependent Variable (DV): Plant growth (measured as height, number of leaves, or biomass). This is the variable we observe/measure.
3. Procedure:

• Select 30 identical plants (e.g., bean plants) and divide them into 3 groups (10 plants per group).
• Group 1: No fertilizer (control).
• Group 2: Organic fertilizer (e.g., compost).
• Group 3: Synthetic fertilizer (e.g., NPK).
• Place all groups in the same environment (same light, temperature, water, soil).
• Measure plant growth (DV) weekly for 8 weeks.

Part F: Controlling Outside Factors
