flame lab

Essential Question: Colors indicate any metals energy level





1. Some other chemicals might be stuck on the bunsen burner.
3. Identification of an element with only one property is invalid because other substances could burn off the same colors.
4. The colors in the flame test are produced because of the substances energy level and the amount of oxygen.
5. The substances in increasing energy level are carbon, BaCNo3, KNO3, Sr(NO3), LINO3
6. The heat releases the energy

                                                                     Oreo Cookie Lab


              Author: Jak Klosowski, Pentucket HS.
              Date: 9/20/13

Students measured the filling in three types of Oreo cookies to determine if filling amounts matched advertising. 
Hypothesis: I thought that the filling would be a little less than what was advertised. 

Method:  1. Weigh the mass of the boat
2. Weigh the mass of the boat with the filling in it 
3. subtract the boat with the filling minus the boat without the filling
4. repeat steps 1-3 with double stuffed and mega stuffed. 
5. Compare data and advertising.

original stuffed filling- 3.35 grams          1.000
double stuffed filling-6.3 grams              1.880
mega stuffed filling- 9.04 grams             2.698


Conclusion: The advertisement was close to being true but not quite 100% true.
