MSM Unit 1, Lesson 3: Decoding & Modifying a Collision Model

Posted June 6, 2024 by bperret

In this lesson students see a StarLogo Nova model of turtles colliding. Then they look under the hood of the model to see if they recognize any of the code blocks being used. (*Students are often surprised to see that the code they generated in the playground is actually used to run the model!) Students identify where in code the ratio is being produced and what the ratio of turtles is before and after the collision. Finally, students get to pick a ratio they want to produce and modify the model code so that upon collision the correct quantity of turtles is being produced to make the ratio intended. The code is run to see if the correct ratio was produced.
