Objective: SWBAT build a histogram in order to display the variation of traits that exist in a single population.

Do Now: 

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.

Guided Notes: 

Vocabulary:
 Distribution: the number of individuals with each trait in a population
 Histogram: a graph that uses bars to show how characteristics or values are distributed within a group
 Population: a graph that uses bars to show how characteristics or values are distributed within a group
 Trait: a specific characteristic of an individual organism
 Variation: any difference in traits between individual organisms
 Abiotic: not living organisms
 Biotic: living 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.
