1 gummy bear
1 triple beam balance
1 metric ruler
1 cup, labeled with group members & period
250mL of water
1 graduated cylinder
1 -250mL beaker
1 set of colored pencils
III. Procedure
1. (DAY 1) Chose a gummy bear!
2. Record the color of your gummy bear and draw a picture of your gummy bear (using color) in
the data table
3. Measure the length, width, thickness in cm and record in the data table.
4. Find the volume(you need to multiply the length x width x thickness.) and record in the data
table.
5. Zero (or tear) the scale. This is when you adjust the scale to make sure it is resting at zero
before you begin measuring.
6. Find the mass of your gummy bear in grams and record in the data table.
7. Find the density(divide the mass in grams by the volume in cm3) and record in the data table.
8. Find the volume using the water displacement method by filling a graduated cylinder with 50
ml of water. Then gently drop your gummy bear into the graduated cylinder and record the
amount of water displaced.(original ml- new ml).
9. Record your information on the chart below
10. Carefully pour the entire contents of the graduated cylinder (gummy bear + 50mL of water) into
your cup. Make sure it is labeled with your group members’ names and period.We will leave
the gummy bear overnight in the water!
11. Clean up your lab station by returning all supplies and washing your table.
12. (DAY 2) Carefully take your gummy bear out of the water and place onto a paper towel. Be
VERY CAREFULY – they are FRAGILE!
13. Repeat steps 3 through 9
14. Determine the Amount of Change () for each column between Day 1 and Day 2. Record your
information on the data table

E. Analysis Questions
1. Which change is greater- volume or mass? What evidence have you generated to explain your
opinion?
