The Bobbing Apple Story
Purpose: To demonstrate that density is a characteristic property. To show the relationship between density and why things float. To practice collecting data and performing density calculations.
Observations: We used a red Washington apple. When in the water it floated. After each consecutive bite the apple continued to float. The apple tasted sweet. After each bite the apple displaced less water. The lower the mass of the apple, the greater density it had.
Data Table:
# of Bites Mass of Apple (in grams) Volume of Water Displaced (in mL) Density of the Apple
0 110.66g 93mL 0.84
1 104.19g 90mL 0.86
2 96.80g 87mL 0.89
3 90.16g 81mL 0.90
Trial # Mass of dry grad. Cylinder (in grams) Volume of Water (in mL) Mass of Grad & Water (in grams) Mass of Water Only(in grams) Density of Water
1 26.20g 6.0mL 32.33g 6.13g 1.02
2 26.20g 4.8mL 31.03g 4.83g 1.006
3 26.20g 3.1mL 29.30g 3.10g 1.00
Calcuations:
Density = Mass / Volume
Water Density
Apple Density
110.66 / 93 = 0.84
104.19 / 90 = 0.86
96.80 / 87 = 0.89
90.16 / 81 = 0.90
