Natural Selection Simulation - Phet

http://phet.colorado.edu/en/simulation/natural-selection

Introduction: This simulation shows a bunny population and how it changes over time depending on limiting (selection) factors. The simulation is java based and will run in most browsers, though you may need to download it first to run it. Your task is to use the simulation to answer questions about how bunnies change over time.

General Observations

1. What are the variables you can control in this simulation?

 

2. What happens if you have no selection factor (food or wolves) clicked?


If you add a selection factor, how does this affect your population of bunnies?

 

 

bunnyExperiment 1: How Does the Food Scarcity Affect Bunny Populations

Sample Hypothesis: If you limit the amount of food the bunnies have available, then evolution will favor traits that_____________________________________________

Instructions: Change the settings of your bunny populations so that you can investigate how food affects bunny populations

Some questions to consider as you make observations:

Assignment: Based on your observations and data, make a CLAIM that answers your experimental question. Provide EVIDENCE that supports your claim - this should come directly from your simulation data. Then provide REASONING that explains how or why the data counts to support your claim. You should use one or more scientific principles that are important to the claim and evidence.

  Accomplished (3) Proficient (2) Developing (1)
CLAIM Makes an accurate and complete claim, uses complete and grammatically correct sentences Makes an accurate, but incomplete claim, or grammatically incorrect Claim is not accurate, incomplete, or unintelligible
EVIDENCE Provides appropriate and sufficient evidence to support claim by referencing specific data, observations, or text evidence (for readings) Provides appropriate data but insufficient data, too general or lacking in details Provides evidence but it is insufficient, inaccurate, no details
REASONING Provides thorough reasoning that links evidence to the claim, references scientific principles that are relevant to claim Provides reasoning that links evidence to the claim, lacks scientific principles Does not provide reasoning, or reasoning does not link evidence.
