Lab Procedures
This round of the lab required the "parent" to do nothing to interfere with the bubbles, representing a "Sink or Swim" scenario.
What is Round 1?
This type of curve is characterized by high survivorship for the young, with most individuals living into "old age."
What is a Type I curve?
Because they produce few offspring and provide intense care, these large mammals are a classic example of a Type I curve.
What are elephants?
This term describes the effort by parents to help their offspring survive.
What is parental care?
According to the student evidence, the "bubble babies" in Round 1 popped almost immediately because of this.
What is a lack of parental care (or no care)?
students used these two items to provide "parental care" and keep their bubbles afloat.
What are hands and paper fans?
Species with a Type III curve typically produce this many offspring.
What is a very large number?
This common backyard bird is used as an example of a Type II curve because they face a moderate, constant death rate.
What are robins?
This is defined as a group of individuals of the same species living in the same area.
What is a population?
This mathematical value was calculated for each round to compare the results on a bar graph.
What is the average age at death (in seconds)?
This was the maximum number of seconds a bubble could be recorded as "alive" before the timer stopped.
What is 25 seconds?
A Type II curve indicates that an organism's chance of survival is this throughout its entire life.
What is relatively constant (or equal at any age)?
These amphibians fit a Type III curve because they lay many eggs, most of which die at a very early age.
What are frogs?
This term refers to the pattern of death within a population.
What is mortality?
Parental investment acts as this against environmental hazards, such as the ground or wind.
What is a buffer?
bubbles that failed to pass through this specific obstacle were recorded as dying at 1 second.
What is a hula hoop?
According to the lab results, Round 3 (the hula hoop obstacle) most closely resembles this curve type.
What is a Type III curve?
Name one of the three organisms mentioned in the lab that produce large amounts of offspring and die very young.
What are oysters, fish, or plants?
A graph that indicates the pattern of death in a population is called this.
What is a survivorship curve?
In Round 3, most bubbles had a high death rate while young due to these two factors.
What are a lack of parental support and environmental obstacles?
This was the primary purpose of the "Bubble Babies" lab.
What is determining if offspring survive longer with more parental care?
This round best represented a Type I curve because parental care allowed for the longest survival times.
What is Round 2?
Humans in highly-developed countries typically follow this survivorship curve.
What is a Type I curve?
These are the young born to living organisms.
What is offspring?
This is the final claim made regarding the relationship between care and lifespan.
What is that increased parental care directly leads to higher survivorship and longer lifespans?
