Create a Working Ecosystem
Create a Working Ecosystem
Students will create a working ecosystem, including a three-level food chain.
In a lake, you will have algae that grows, small fish that eat algae, and a bigger fish that feeds on small fish.
Students will code the computer to:
Create a background that includes a lake.
Create an “algae” turtle that stamps itself to represent growth.
Create a “prey” turtle that wanders around and eats (erases) algae when it finds any.
Create a “predator” turtle that wanders around and eats the smaller fish.
Algae and fish all use color detection to “stay” in the lake.
Predator uses collision detection to detect small fish and eat them.
Grades: 3 - 10
Time: maybe 5 60 minute sessions
