Procedure summary: (what did we do?) We used the cooled biscuts that we made and baked to see how much mass was really in the biscuts. To do the measurement we used a metric scale and thats how we got the mass of the biscuts.
Lab Data:
Mass of Biscuits: The mass of the biscuts were 105 grams.
Initial volume of rice in graduated cylinder B: The volume of the rice in graduated cylinder B was 812 grams.
Volume of rice remaining in Graduated cylinder B: There was 663 grams left.
Total volume of rice and biscuits in graduated Cylinder A: All together we had 250 grams in Cylinder A.
Volume of rice used: The amount of rice that we used was 149 grams.
Volume of biscuits: The volume of the biscuts that we had were 101 grams.
Calculate the density of the biscuits (density= mass / volume): 105/101=1.04 grams
1. What was the average density of your biscuits? The average density of our biscuts was 1.04 grams.
2. Which is a more accurate measurement: mass or volume? Why? The answer is mass. It was eaiser because it has less chances for a mistake.
3. How would you measure the volume of an irregularly shaped object in water? 1= measure volume of water in graduated cyclinder. 2= put the object into the water. 3= We would record the volume of both. 4= subtract the volume of the water from the total volume.
4. What relationship is there between density and texture of the biscuits? Big, fluffy biscuts would have less density because they have more air in them.
5. Which ingredient in the biscuits is related to density? Yeast or another leavening agent.
