Gummy Bear Lab
The purpose of this lab is to learn how to set up a lab report and properly use the Scientific
Method.
Question/Purpose: What will happen to a gummy bear when you put it in water over night?
Hypothesis: (use IF, THEN format; give rationale for hypothesis)

Materials (create a bulleted list of ALL materials used, include quantities)
* Plastic Cup
* Gummy Bear
* Ruler
Procedure (written as step-by-step directions)
1. Make qualitative observations and record on separate sheet.
2. Use the data table to show your qualitative observations (for day 1 and day 2).
3. Make quantitative observations (length, width, thickness, volume, mass and density) and
record on a separate sheet.
4. Use the data table to show your quantitative observations (for day 1 and day 2).
5. Label plastic cup with your name and class hour. Add 50 ml of water to the cup. Place the
gummy bear in the cup.
6. Leave cup to sit for 24 hours.
7. The following day redo all observations and record in tables.

Analysis: (this explains what your data means, it MUST include the actual data from your
experiment, ANYTHING you say MUST be backed up with supporting data)
Some questions you may want to answer in this section would include:
Which change is greater, volume or mass? What explains this? Was there a change in density? Why? How do your
results compare to other results? What do the results tell you about Gummy Bears and water? REMEMBER include
all data to back up your “opinions”.
