A student hypothesizes that increased sunlight will accelerate the growth of an avocado tree. How can the student test their hypothesis?(1 point)

1 answer

The student can test their hypothesis by conducting a controlled experiment. Here’s how they could set it up:

  1. Select a Sample: Choose a number of avocado trees that are of similar age and health to ensure consistency in the experiment.

  2. Control Variables: Keep all other growth factors constant, such as soil type, water levels, temperature, and the size of the pots, to ensure that any differences in growth can be attributed to sunlight.

  3. Experimental Groups: Divide the avocado trees into two groups:

    • Experimental Group: Expose this group to increased sunlight (such as placing them in a location with more direct sunlight).
    • Control Group: Keep this group in a location with normal sunlight exposure (for example, a shaded area).
  4. Measure Growth: Over a set period, measure the growth of the trees (e.g., height, number of leaves) regularly.

  5. Record Data: Collect and record data from both groups systematically.

  6. Analyze Results: After the experiment period, compare the growth of the experimental group to the control group to determine if the increased sunlight had a significant effect on growth.

By following this method, the student can objectively assess the impact of increased sunlight on the growth of the avocado trees and validate or refute their hypothesis.
