The Soap Bubble Population

The hypothesis that the bubble population without help would have a type III survivorship curve was rejected because the survivorship curve of this population resembled a type II curve. It likely resembled this type of survivorship curve because the population was likely to die at any point in time, since there were no factors to inhibit or encourage the bubbles to pop, but once they hit the ground or any other obstacle, which could have happened randomly at any point in time, they popped. This population had fairly constant death rate from zero years of age to about eight years of age and from nine years of age to about fifteen years of age.
The hypothesis that the soap bubble population with help would exhibit a type I survivorship curve was rejected because the survivorship curve of this population was actually between a type II and type III survivorship curve. It exhibited this curve because although the death rate was fairly constant during the first thirty years of the population’s life, it leveled off …show more content…
Another source of error could have been that since the experimentation was over a two day timeframe, one group could have used two different bubble bottles to create their bubble populations. For example, the first soap bubble group tested was the one without help and this population of bubbles survived at least ten to twenty seconds after hitting the ground, but the next day, a different bottle was used and when doing experimentation for the bubble population with help, the bubbles had a tendency to pop immediately upon hitting the ground, which would have made it appear as though the populations without help did survived longer than the populations with help because two different bubble bottles were
