Section Animal Science Unity Unit 9: Food, nutrition, and digestion
The Lesson Title Lesson 1: Introduction to food and nutrition
The learning objectives of the students
As a result of this lesson, the student will:
1. Understand the fundamental role of a balanced diet plays in the maintenance of healthy animals.
2. Put into practice the scientific processes.
Time Instructional time of this lesson: 90 minutes.
-Time can be assigned to more than one class period 1.5 with an introductory section of introduction to the lesson of nutrients in the second half of the day.
The tools, equipment, and supplies
- Microwave
- 8 Mixing bowls
- 4 bread pans
- Measuring cups
- The ingredients as indicated in the recipe
- Hot Pads
- Napkins
Interest approach
For this project, you will need to divide the class into four groups: Each group will bake 1 loaf of banana bread, according to the instructions given to each group.
Group #1: cook the banana bread, exactly as the instructions. Take your time and make the best banana bread that has ever made.
Group #2: Bake the banana bread according to the directions, although I do not want to include all the sugar.
Group #3: Bake the banana bread according to the directions, although I do not want to include any flour or baking soda.
Group #4: Bake the banana bread according to the directions, although I do not want to include any product that has any measurable on of moisture (water).
-This includes: bananas and eggs
Each of these four loaves of banana bread represents four different animals. The ingredients are what we feed our animals. Remember to come back to the unit one when we discuss the scientific method. We will perform an experiment to see what happens today to our cattle (bread) When we retain the nutrients (ingredients). When I say "hypothesis" I want each of the four groups to take five minutes to write a hypothesis for your prescription. I also want to identify the independent and dependent variables. Have a Question? The hypothesis!!
Remind the class the difference between independent and dependent variables refer to unit 1, Lesson 6 in scientific research.
Walking around the class and help students.
Now I want you to each group shall designate a reporter. A representative from each group ask to give his hypothesis for your prescription.
What were the independent variables within each of the recipes? (sugar, flour, and baking soda, and bananas and eggs)
What is the dependent variable? The quality of the bread ()
Ask the following questions to stimulate discussion in class.
Remember that we are using this experiment to draw an analogy between the loaves and our cattle. What would happen if we retained proteins form a serving? What would happen if we retained the vitamins and minerals?
Now we are going to continue with our experiment of nutrition.
Summary of content and teaching strategies
Objective 1 The student will understand the vital role it plays in a balanced diet
Keep healthy animals
Objective 2 The student will have to put into practice the scientific processes.
-Leave laboratory sheets
Each group should be careful in the mixture of its ingredients. Then start the tasty baking products according to the instructions. (Hint: Preheat oven to 350 F)
How products are baking visit with the class about what they have eaten during the day and they ate what they did.
"Then you can relate this with nutrient/body needs, etc.
-Every 15 minutes, each group should check their creations as baking and record what is happening to your product. On the basis of their observations do any of the students want to modify their hypotheses?
At the end of the pull the products from the oven and return to class with the finished products. Ask the class to record observations and collect data from all four products. You can draw a conclusion or make recommendations based on what you have seen?
-Students will complete your tax return and deliver it. Laboratory
-This will lead directly to lesson #2 and the importance of nutrients.
-All the macro and micronutrients that should be present in the correct proportions.
Review/Summary
These four loaves represented the animals or the health of four animals. Why was an animal or a single recipe that came out of the bread? Call on several students of explanations. What happened to the following three loaves of bread? What led them to cook so bad? In this experiment, the bread represents the health of our animals. Without the proper nutrients in adequate amounts of the health of our animal "flops".
Banana Bread Recipe Lab
Each member of the group must follow the indications according to the instructions given by the teacher. This may or may not follow the recipe exactly as shown below.
Banana Bread Recipe:
1/2 cup softened butter or margarine
-1 cup of granulated sugar
-2 eggs
-1 cup mashed ripe banana (3 medium banana)
-2 cups flour
-1 teaspoon of baking soda
1/2 teaspoon baking powder
1/2 teaspoon of salt
-1 cup of walnuts
Bowl #1
1. Mix together butter and sugar together. Add an egg at a time, whisking until smooth.
2. A mixture of mashed bananas.
In the second bowl:
3. Mix the flour with the baking soda, baking powder, salt and nuts
4 Combine ingredients in a bowl #1 and #2 and mix the dry material until everything is wet.
5 Place the content in bread pan greased.
6. Bake in the oven at 350 degrees for 45 minutes to 1 hour or until the barb pick inserted into the center comes out clean.
7. Let stand for 10 minutes before removing from the pan.
