Calorimetry Lab

Which foods have the most calories? Hypothesis: If we burn the food then the heating released will be measured as calories because the energy stored Inside Is released as heat and light. Parts of the experiment Control Group-water Experimental Group- different foods Independent variable- Type of food Dependent Variable- temperature of water Controlled variables- water temperature of unheated water Materials Stirring Rod, Beaker, ring clamp, evaporating disk, matches, crackers, marshmallows Analysis Questions 1 . Which foods gave off the most calories/gram?Marshmallows 2. Which foods gave off the least calories/gram? The chips give off the least, when they were burned we realized they had the least. 3. How do these results compare with your prediction? The result are somewhat like my prediction, I predicted that when the food is burned it will release heat and light.I liked this lab because it's a way to figure UT certain things within food substances. I probably would not take the ti me out to try it out at home, but I did like the lab. Despite us being very careful with trying to make everything accurate I don't think everything was so accurate. However scientists do this all the time to fugue out the calories of foods, so it is still a legit experiment. The temperatures did not change drastically it was mostly around 4 or 4. 5 degrees Celsius. Citation Mar. 2013. Web. 14 May 2014. Http://www. Chem†¦ Davidson.
