Read the following scenario and answer the questions that follow.

Nick’s mother packed him sliced apples in his lunch everyday. Nick was disappointed when he would open his lunch and find brown, mushy apples. Nick decided that he would try to find a way to keep his sliced apples crisp and white. He packed apple slices 3 different ways and recorded his observations in the chart below.

Appearance Texture Apple Slices brown Soft and mushy Apple slice & ¼ cup sugar water white crisp Apple slice & ¼ cup sugar white soft and mushy 44. What was the control in the experiment?

45. What was the independent variable?

46. What was the dependent variable?

47. Using your knowledge of diffusion, explain why the apple slice was crisp with stored in sugar water

but soft when stored in sugar.

48. Label the diagram.
