Question
What are the key considerations for designing a safe and valid investigation into plant responses to light and gravity?
Answer
When designing an investigation into plant responses to light and gravity, it is essential to control variables such as light intensity and direction, temperature, and soil type. Additionally, using repeated trials ensures that the results are reliable and can be accurately analyzed.
Explanation
This answer is strong because it identifies specific control variables and emphasizes the importance of repetition in experiments. The question tests the understanding of practical design in scientific investigations.
Common mistake
Ignoring Control Variables
Students often forget to identify and control variables that could affect the outcome of their plant-response investigations, leading to unreliable results.
Ensure to list all control variables and explain their importance in maintaining the validity of the experiment.
