Kyle Fanselau Science Experiment
Kyle Fanselau Science Experiment Paper.
Guiding Question
The over-arching question trying to be answered is will the Law of Conservation of Matter be violated if popcorn kernels are popped and the popcorn weighs less than the same kernels in the un-popped state? .
Purpose
To determine whether the Law of Conservation of Matter can be violated when you pop popcorn kernels and the form of the popcorn kernels changes to popped popcorn.
Hypothesis
If the popcorn kernels pop and weigh less after it is popped, then the Law of Conservation of Matter will be violated.
Materials
One Hot Plate 20 Popcorn Kernels One 400 ml Beaker One pair of Beaker Tongs One pair of Heat Resistant Gloves One Pair of Safety Googles One Watch Glass with a 5 cm radius …show more content…
Independent Variable – The kernels of corn that change into popcorn. Control Variable – The beaker and the scale. Controlled Variable – The mass of corn kernels because during the experiment the mass is compared before and after. Controlled Group – The number of kernels. The same number of corn kernels were used each time. Experimental Group – Each of the seven times that the experiment was conducted. There was not a significant difference between the Initial Mass and Final Mass of the seven groups. Of the seven groups, only one group (group 1) had a higher mass after the experiment steps were followed. The other six groups had a lower final mass after the experiment steps were followed. This outcome is not what I expected.
There were several possible sources of error in this experiment.
Temperature of the flame was not measured, so it was not possible to determine if the flame temperature varied during the experiment. A varied flame temperature could affect the time it takes the corn kernels to pop. In the future, a burner with a temperature gauge could be used.
The room temperature was not taken into account. It is possible that room temperature could affect how long it takes kernels to pop. To determine the room temperature, the experiment could be conducted in a room at 68 degrees, a room at 72 degrees and a room at 75
