Scientific Process

Crushing Cans

Problem: What is the impact of the amount of water when you are crushing a can.

Hypothesis: I think that the more water in the can the more likely it will compress the most. I think that the mass of the object is more important than any other characteristic.

Experiment:

Materials-

20 Cans

Container

Water

Bunsen Burner

Test Tube

Science/Safety Glasses

Tongs

Variables-

CV: Soda cans, Bunsen burner, safety glasses, container.

IV: Amount of water used for the soda can.

DV: The amount of compression it has on the soda can.

Procedure- In order to test our hypothesis, we have gathered out materials and tools for the experiment.

Take a container and fill it up almost all the way with water so when you see the steam coming from the can, you can drop it in.

After that, you need to take a test tube and fill it with the certain amounts of water. This is the water the you will eventually pour into the soda can.

Once you pour the water into the soda can, you need to hold it over the Bunsen burner and wait for the steam/smoke to float out of the can due to the boiling water in the can.

After you see the steam, you would need to count to ten and dump the can upside-down, using the tongs, into the container that you filled earlier with water.

Once you complete all of the steps, you can then repeat each one again using different water amounts. Keep doing these steps until you run out of cans, then you can start gathering and sorting the data.

Observation: I observed that the more water you put in the less the can will crush, and the less water you put in the more the can will crush.

Conclusion: I think that that is because with more water in it the less area there is for the can to crush. I think that you need to heat the can so the hot water can react to the pressure that you are putting it through while dumping it in the container.
