D’vante Belisle 11/8/10 D-Block DYO Investigation __Background:__ Saturated fats are the fats that are very unhealthy for you, that store in your body. Saturated fats can be found in beef, & beef products. Unsaturated fats are the more healthy fats, and should be eaten. The percentage of fate show much fat can be found inside of something, more specifically, food. __Purpose:__ I have composed a lab to see what is the percentage of fat that is in cupcakes. __Materials__: The materials used for this lab were Ø Acetone Ø Cupcakes Ø A Petri Dish Ø A Gradulated Cylinder Ø Beaker Ø Stirrer __Prediction__: I predict the average fat percentage between the foods that were tested is 9%-15% because a cupcake is made up of large fatty components, and that could cause the percentage of fat to be high. __Data:__ __Conclusion__: Multiple students have tested varies food for their percentage of fat. If we extract & calculate the fat mass of a butter bagel, the percentage of fat that they found was 12%. This would make sense if majority of that fat came right from the butter. Although I did a lab on cupcakes, the data that was found was inaccurate and could not be used because the percentage of fat increased after the extraction. Ways to prevent this error is to carefully read the instructions before and while doing the experiment. The results of the butter bagel matched my prediction.
