Solution:
As the experiment is to compare the way in which heat is transferred to water in a pond as opposed to the soil at the edge of the pond.
heat transferred = change in temperature.
a. Mix water and soil in a container, place it in the sun, and measure the temperature of the container.
From this investigation, we can't measure two different temperatures to compare them.
b. Place soil and water in separate containers, place them indoors, and monitor the temperature of the containers.
If we place the containers indoor, the sunlight will not be reachable to make the temperature change in water.
c. Place soil and water in separate containers, place them in the sun, and monitor the temperatures of each container.
We need to measure the temperature of heat is transferred to water in a pond as opposed to the soil at the edge of the pond, so two separate containers are not useful.
d. Place soil in the bottom of a container and water on top, place it in the sun, and measure the temperature of the container.
After placing the container for a specific amount of time in sunlight and then separating the sand and water to measure the temperature quickly, we can compare the difference.
