1 Coke vs. Diet Coke Lab Science Starter-Predict which liquid is more dense: hot water or cold water. Stamp ISJ 43 (bottom questions 1-4) HW-Finish ISJ 45-Layering Hot and Cold Water and ISJ 46-Convection Response. Due tomorrow!

2 Coke vs. Diet Coke Similarities Dark pop No potassium Similar flavors Citric acid Crisp taste Carbonated water Differences Diet coke-no sugar (aspartame) Coke-sugar and corn syrup D. coke-more caffeine D. coke-more sodium

3 Make a Prediction Coke Denser because: Diet Coke Denser because:

4 Experiment Write an experiment to prove that one pop is denser than the other. Step 1: Step 2: Step 3: Step 4:

5 The denser pop is… Coke-Cola Classic. This pop is denser because… It has more sugar which adds mass to the pop.

6 Question 1 D= m/v D= 3.2 g/4 mL D= 0.80 g/mL

7 Question 2 D=m/v D=7g/2cm 3 D=3.5g/cm 3

8 Question 3 D=m/v D=0.4g/1.5cm 3 D=0.27g/cm 3

9 Question 4 D=m/v D*V=m 7.8g/cm 3 *10m 3 78 grams
