Aluminum Can Lab
By: Isabelle Tobin, Erin Cassidy, and Mackenzie O'Hara
Pose Question:
How would putting a hot can in cold water effect the volume?
The first step, in testing our hypothesis, was to put 3ml of water into our can. Then, we heated it up for 0 seconds so that we had something to compare to. Next, we heated another can with 3mL of water on heat 10 for 30 seconds the entire time so we could keep the same temperature. After that we turned our can over into the water. Then, we repeated these steps multiple times, adding 30 seconds on to our original time.
Hypothesis:
The hotter the can is the less volume there is.
As the can got hotter the volume decreased.
There was more steam coming out of the cans as the cans got hotter.
When the cans crushed it made a loud sound.

Procedures:
hot plate
aluminum cans (12 oz.)
container of water
tongs
stopwatch or timer
safety goggles (optional)
Our question, How will putting a hot can in water effect the volume, partially supported our hypothesis that the hotter the can the less volume. This is because, although most data supports the hypothesis, one section of the data does not and breaks the pattern.
Errors that may have been made:
water left in cans
cans moved to water at an angle
incorrect water measurements
incorrect times left on hot pad
Ideas for future experiments. In order to further prove our experiment, all we would need is more time and a more presise hot pad to ensure it was the same temperature the whole time. We would also need more time so we could do more trials with smaller intervals of time.
