Temperature and Potato Chips
Title: Food Energy Lab Report
Date of Activity: 8-28-13 through 8-29-13
Purpose: The purpose of the lab was to measure the amount of energy contained in a gram of certain foods.
Hypothesis/Prediction: I hypothesize that some of the foods are going to be difficult to burn.
Procedure:
1. Weigh the weight of empty can and food items.
2. Fill can approximately one third full of water.
3. Weigh the can after water is in the can.
4. Take the temperature of the water in the can.
5. Place the first food item under the ring stand.
6. Set the food on fire then quickly place the can on the ring stand above the burning food.
7. Once the food has extinguished take the temperature of the water in the can.
8. Weigh the food that has been burned.
9. Pour out water that is in the can.
10. Repeat steps 2-9 for each food item.
Safety:
Wearing goggles. Wearing aprons.
No eating of the lab materials.
Securing long hair in a ponytail.
Materials:
Marshmallows.
Tortilla chips.
Potato chips.
Barbeque lighter.
Thermometer.
Stirring rod.
Ring stand.
