This graph shows the number of individuals alive at each age. In natural populations, three basic trends of survivorship affecting population have been identified. Type 1 Low mortality in early life, most deaths occurring in a narrow time span when organism is older. Three different populations of soap bubbles will be formed. Once the bubbles leave the wand the group members do nothing to keep the bubble in the air.
Bubble dies once it bursts.
The survivorship frame is held 12 inches from the wand. Bubbles that fail to pass through the frame are considered dead. Bubbles that pass through the frame are timed. They are the only surviving portion of the population. Do not attempt to manipulate the frame or the wand to increase the bubble s chances of passing through the frame.
