Calorimetry Lab

Which foods have the most calories? Hypothesis If we burn the food then the heat energy 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- cause 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(prenominal) calories/gram? The chips give off the least, when they were ruin 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 its a way to figure UT certain things within food substances. I probably woul d not take the time out to try it out at home, but I did like the lab. Despite us being very careful with attempt to make everything accurate I dont 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.
