Can Crushing Scientific Process

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 impact it will receive. There is more mass and weight in the can, so when it burns and gets put in water, it will make a bigger compression. 

Experiment:

Materials-

1. 20 Cans
2. Container
3. Water
4. Bunsen Burner
5. Test Tube
6. Science/Safety Glasses
7. 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.

1. 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.
2. After that, you need to take a test tube and fill it with the certain measurements  of water. This is the water the you will soon pour into the soda can.
3. Once you pour the water into the soda can, you need to hold it over the Bunsen Burner and wait for the steam to float out of the can due to water.
4. After you see the steam, you would need to count to five and dump the can, using tongs, into the container that you filled earlier.
5. Once you complete all of the steps, you can then repeat each one again using different water amounts.

 Observation:  After we started the can crushing, my group noticed how when there was a smaller amount of water in the can, the bigger the compression. Each time we changed the water so then the temperature wouldn't be cold for a can and hot for another. As we tested the 20 milliliter can and then the 250 milliliter can, the compression was different. Once we filled up each one with water, we noticed how the smaller the water, the smaller amount of water would fit in the can. For example, the 20 milliliter can could fit 63 milliliters afterwards. Whereas the 250 milliliter can could only fit 235 milliliters.

200-350

Conclusion:   My group for this science project wanted to test how much water in milliliters would be able to fill up in the can after the compression.  In our hypothesis, we thought that the more water in the can, the more it will crush.  Although, our results stated that the more water  in the can it didn't have a big compression. 

After the first time we started the can crushing, I noticed how 25 milliliters was a big compression on the can.  Every time I put more water into each can, the cans wouldn't have that big of a compression.  When it started to get to about 150 milliliters of water, some of the cans would have a big compression, where some wouldn't have any sign of a compression at all. It started to increase the amount of water that we put in the can one we were finished.  So my hypothesis was proven wrong and with the less water, the greater the compression on the can.
