OVERVIEW: To help students have an understanding of energy in food by measuring the energy in calories.
OBJECTIVES: Students will be able to :
If the peanut sputters and goes out before it looks all burned up, get a new half peanut and freshwater, and start over.
When the peanut looks all burned up and goes out, take the temperature of the water again. Record the temperature on your worksheet.
*Amount of water used = (___milliliters = ___grams) *Temperature of water in degrees C before burning *Temperature of water in degrees C after burning *Difference in temperature *calories = (mass of water in grams) x (temp. change in degree C) Example: 10 grams of water are heated 15 degree C; calories = (10 grams of water) x (15 degree C) calories = 150 calories. This calculation is in small calories. There are a thousand calories in a food Calorie, or large Calorie. To convert calories to Calories, divide the number of small calories by 1000. *food Calories or large Calories = small calories / 1000
