practice: scientific method\nread each scenario and answer the questions to the right.\nmaggie 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 3 weeks she measures the moistness of the brownies, and records her results.\n1. independent variable\n2. dependent variable\n3. hypothesis\n4. control group\n5. experimental group\n6. constants
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:
- Presence of bread in the container
- Moistness of the brownies
- Brownies in containers with bread will stay fresh and moist longer
- The 3 brownie - containers without bread
- The 3 brownie - containers with bread
- Size of brownies, type of brownies, type of containers, location
