Subject: Lifetime Nutrition & Well
Conducting and experiment utilizing food and the scientific method
The Scientific Method

Vocabulary - Natural, Homogenized, Non-Homogenized, Saturated fat, Trans Fat

Expected Outcome Of This Lesson Plan-
1. Understand that food, science, nutrition, and bacteria go hand-in-hand
2. Understand how bacteria can escalate with certain foods
Teacher Objectives-
1. Students will learn the scientific method by designing a food experiment to answer a question in how to solve a simple everyday problem
2. Students will identify if bacteria will play a role in the way their food item is stored

TEKS 130.245: 4A, 5G, 6A-C
2 jars of Peanut Butter (1 stored inside the refrigerator and 1 stored at room temperature, Jelly, Bread, Internet Access
Teaching Methods-

1. Lesson Introduction-

1. How does science play a role in food storage and bacterial growth?

2. Lesson Progression-

1. Begin by going through the scientific method and relating it to food, food storage, and foodborne illness

3. Guided Practice-

1. Have students (in groups of 2) practice developing an experiment by using peanut butter and jelly as their material
2. Tell them you want to know how to make a peanut butter and jelly sandwich quick with the safest peanut butter jar
3. Let them know them that you keep your peanut butter in the refrigerator and your friend keeps theirs in the pantry
4. Ask them which one should you use if I want to make my sandwich fast and safe.
5. Let the students design and conduct an experiment using the above question.
6. Define steps in experiment:

Problem -- What question are you investigating?

Hypothesis -- What do you think will happen?

Materials -- List the supplies needed to conduct the experiment.

Procedure - List the steps followed to complete the experiment.

Data/ Organization/ Interpretation - What did you see, hear, or smell? You should use a graph, chart and or illustration.

Summary -- Explain the results using science vocabulary.


4. Student Practice-

1. Develop 3 Further Questions -- Good scientist always think of something else they’d like to try!

5. Learner Accommodations-

2. Collaborative Learning

6. Assessment-

1. Have groups present their projects and findings to the class

7. Lesson Closure-

1. Have students "eat" their experiments!
Measuring Student Progress-
1. Groups will be observed and grades will be based on contribution.
