Food as fuel: how our bodies use it. This lesson package examines the basic need for calories, the potential energy of different foods (carbs, proteins and fats) and how our bodies convert the food we eat into the energy needed to keep us alive (see below for more details). It includes the lesson (student and teacher versions of the Power Point), 2 embedded videos, a special case look at the energy requirements of elite athletes and a student lesson handout as a word document. This lesson is designed for a senior level biology course.
Included in the lesson package is:
- The teacher version of the Power Point
- The student version of the Power Point
- 2 videos embedded into the Power Point
- Student lesson handout
In order, the lesson covers:
- Types of fuels
- The energy content of fats
- The need for Calories
- Potential energy of foods
- The combustion of carbohydrates
- The controlled oxidation of carbohydrates
- Energy carriers
The student version of the power point contains multiple blanks that need to be filled in throughout the lesson. These blanks are conveniently underlined and bolded on the teacher copy. I have found this to be the most effective means of keeping my students engaged and active without having them write everything out. This also leaves more time for discussion and activities.
