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?

I liked this lab because it's a way to figure UT certain things within food substances. I probably would not take the time 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.
