Answer

Brief Explanations:

A control is a fixed standard for comparison in an experiment, while a variable is a factor that can change. For the second - part, assume the problem is "Does plant growth depend on the amount of sunlight?". First, observe plant growth in different sunlight conditions. Then, form a hypothesis like "Plants grow better with more sunlight". Next, design an experiment with a control group (plants in a set amount of sunlight) and experimental groups (plants in varying amounts of sunlight). Collect data on plant growth (height, number of leaves etc.). Analyze the data to see if the hypothesis is supported or not.

Answer:

  1. A control is a standard for comparison, while a variable can change during an experiment.
  2. Problem: Does plant growth depend on the amount of sunlight? Steps: Observe, form hypothesis, design experiment (with control and experimental groups), collect data, analyze data.
