Someone please help me before 1:00 Maggie loves fresh brownies, and her grandma told her if she places a piece of bread in the storage container with the brownies, the brownies will stay fresh and moist longer. Maggie decides to test this idea. She bakes a batch of Betty Crocker brownies. She places 6 brownies in 6 individual tupperware containers. Each brownie is the same size and placed in the same location. She adds a piece of bread to three of the brownie containers, and leaves the other three alone. Each day for three weeks she measures the moistness of the brownies and records her results. What is the independent variable? What is the dependant variable? What are the constants? Hypothesis? What are the control groups? What is the experimental group?
