Think about what you have learned so far about populations in general and the rough-skinned newt population that has lots of predators in the park.
What prediction would you make about the poison-level traits in this population? Explain.
Vocabulary:
1. Distribution: the number of individuals with each trait in a population
2. Histogram: a graph that uses bars to show how characteristics or values are distributed within a group
3. Population: a graph that uses bars to show how characteristics or values are distributed within a group
4. Trait: a specific characteristic of an individual organism
5. Variation: any difference in traits between individual organisms

Complete each mission in the Sim by adjusting the trait-level and variation sliders. Zoom in to the environment to observe the individual organisms. draw the histogram of each mission, then mark each mission as complete as you go.

How can histograms be used to help describe a population?
CFS:
Accurately identifies relationship and trends in the data set
Accurately describes the relationship between different variables in a population
Draw the following histograms with a population of 12 individuals on the graphs plots below:
