This PBL activity was implemented during the Macromolecules unit. Macromolecules are tough to teach, in my opinion, because frankly they can be a bit boring to a 10th grader. I designed this activity this year to try to show my students why the understanding of Macromolecules is important in day to day life and that they do have relevance.
Macromolecule PBL: Efforts Against Child Hunger
The World Food Program is the world’s largest humanitarian agency fighting hunger worldwide. On average, WFP aims to bring food assistance to more than 80 million people in 75 countries. Malnutrition affects millions of people around the world. A third of all deaths in children under the age of 5 in developing countries are linked to under-nutrition. WFP’s role in fighting malnutrition is not only to treat it but also to prevent it becoming severe in the first place.
The World Food Program is employing you to design a new nutrient rich recipe that will be used to feed millions of people worldwide. The price of food and fuel has increased exponentially and the World Heath Organization has had to cut your budget by 18%, which means that you have a total of $2.25 per meal per child. Ideally, you will be able to feed each child 3 times per day. A typical serving portion is 1 cup of prepared food.
Here is what you need to focus on:
- The recipe must include all daily nutritional dietary needs (both macro and micro nutrients)
- The product needs to be as dry as possible to limit microbial growth. Workers/recipients in the field can add milk or water to make a paste.
- Food base should be easily grown with limited amounts of processing.
- This food needs to taste good, period.
You will need to make this food for the class and we will have a taste test at the end of the project. Please submit your receipts so that we know what the actual cost of your product encompasses.
End Products of this Project:
- The food item you prepared from your recipe
- Your written proposal should include: receipts, recipe, and nutritional information about your product, why your product should be selected by the WFP
If you implement this project in your class, let me know how it goes. Keep in mind food allergies and tell your kids to stay away from nuts as an ingredient.
