sale which we are expecting to sell all of them in the school farmer market. Conclusion: The cookies that we made during each lab showed most of the benefits and disadvantages of making our own cookies compare buying commercial cookies (saving money‚ healthier version‚ taste‚ and texture). I believe‚ I can use all these experiences that I gained during each cookies labs at home too. Also‚ it will be helpful and useful in food service. For instance‚ as a register dietitian‚ I can approach any desserts

The objective of the deicer lab was to successfully conduct experiments to determine the usefulness of magnesium chloride as a deicer. To find how successful magnesium chloride is as a deicer‚ experiments were conducted to determine the freezing point depression‚ enthalpy of dissolution‚ the impact on the surrounding environment‚ and also the expenses of using magnesium chloride as a deicer. For magnesium chloride to be determined as a good deicer‚ the reaction with water needs to be exothermic so

Proteomics is the study of proteomes‚ which are groups of proteins in living systems. It is used to examine when and where proteins are being expressed‚ rate of degradation‚ modifications‚ how they interact with other proteins and more. The goal in this lab was to determine the similarities and differences in muscle proteins among 5 species of fish using SDS-PAGE and Western blotting. First‚ proteins are separated based on size. Second‚ antibodies are used to detect the protein of interest. Lastly‚ a substrate

Homeostasis Lab: The Effects of Exercise on Homeostasis Purpose: To discover the effect that various levels of exercise have on specific body parameters. Hypothesis: If a subject walks up and down a flight of stairs for eight minutes‚ then they start to sweat more‚ their heart rate‚ body temperature‚ and breathing rate will increase‚ and there will be a change in their skin color on their arms and face‚ because the body will be trying to maintain homeostasis.

In the crystallization lab (lab 4) part 1‚ we must acquire the best possible pure crystallization of acetylsalicylic acid from aspirin and in part 2 we must obtain a similar pure crystallization of benzil from an impure mixture of benzil. Materials: In lab 3‚ we used 75 g of cloves from which we

was higher than the actual melting point of pure aspirin; 135°C. The phenol test showed that the product is not a pure aspirin by expressing purple color. TLC results weren’t high enough to conclude that the product was a pure aspirin. Overall‚ the lab wasn’t successful due to the low percentage of aspirin that were produced. Out of 2.0 grams of aspirin‚ only 0.7862 grams of pure aspirin were produced. So the percent yield was only 39%. Errors could be made during filtration process and the melting
