While eating a piece of fruit, a group of scientists noticed that some had fruit that was spoiled while others didn't. One scien
tist said they left their fruit on the counter, another left theirs in the fridge, and one left theirs in the freezer. They decided to conduct an experiment to determine where fruit should be stored so it stays fresh longer. The fruit of choice was granny smith apples that were bought at the same time and were the same size. One apple was left on the counter, another in the fridge, one in the freezer, one was left outside on a porch, and a final apple was left in the microwave. All remained in their locations for one week and they tested which apple was freshest. In this experiment, what is the independent variable? A. Type of apple B. Where the apples were left C. Amount of time apples were left out D. Freshness of apple
In the scenario being described the independent variable would be "where the apples were left". This is because where the apple was left does not depend on any other factor for the results to be affected. The freshness of the apple would be the dependent variable because it depends on where the apple was left and for how long, while the amount of time is the controlled variable in this scenario because it remains constant for all groups and was chosen by the scientists.
The moon moves through space in two ways: It revolves around Earth and also rotates on its own axis. The moon rotates once on its axis in the same time that it takes to revolve once around Earth. The changing relative positions of the moon, Earth, and sun cause the phases of the moon.
