Answer

Explanation:

Step1: Identify independent variable

The factor that is changed is the presence of bread in the container.

Step2: Identify dependent variable

The variable that is measured, which is affected by the independent variable, is the moistness of the brownies.

Step3: Formulate hypothesis

The hypothesis is that brownies in containers with bread will stay fresh and moist longer.

Step4: Determine control group

The control group is the group that does not receive the treatment (bread), so it's the 3 brownie - containers without bread.

Step5: Determine experimental group

The experimental group is the group that receives the treatment (bread), so it's the 3 brownie - containers with bread.

Step6: Identify constants

Constants are factors that are kept the same throughout the experiment, such as the size of brownies, the type of brownies (Betty Crocker), the type of containers (Tupperware), and the location.

Answer:

  1. Presence of bread in the container
  2. Moistness of the brownies
  3. Brownies in containers with bread will stay fresh and moist longer
  4. The 3 brownie - containers without bread
  5. The 3 brownie - containers with bread
  6. Size of brownies, type of brownies, type of containers, location
