Lab focuses on calorie content

Which nut has more calories: roasted peanuts or roasted walnuts? The chemistry students were recently asked this same question and completed a lab to find out. Using a homemade calorimeter setup, the lab partners lit a nut on fire and observed how much energy was released. They did this by finding the temperature change of the water in the flask above. They did three trials for each nut to get a sufficient sample size. By the end of the class period, the lab was full of floating carbon pieces and burnt nut smell!

Students had to figure out the trick to lighting the fires!After all the calculations have been completed, students will be able to decide, from their tests, which nuts have more calories—peanuts or walnuts!
Which nut do you think has more calories?
| Donna Uhrenholdtdju0453@yahoo.comElginFarming, nursing | Oct 02, 2007 | As far as the nut question, I have no idea... Just wanted to give you a GRAND "thumbs up" for all the experimentation being done in all science classes you teach Sara, these are memory-producing moments for all students involved, esp. those w/interest in sciences. I remember a lot of these things back in my Earth Science, Biology, Chemistry classes. Donna |
