Grade Level(s) 8th and 9th grade students Subject(s) Science and Math (Algebra I) State Standards Addressed:
Grade 8 Inquiry
GLE 0807.Inq.5 Communicate scientific understanding using descriptions, explanations, and models.
Grade 8 Technology
GLE 0807.T/E.4 Describe and explain adaptive and assistive bioengineered products.
Grade 8 Science-Biodiversity and Change
GLE 0807.5.3 Analyze how structural, behavioral, and physiological adaptations within a population enable it to survive in a given environment.
Description of Project
Students use the ultrasonic sensors and LEGO MINDSTORMS robots emulate how bats use echolocation to detect obstacles in their environments. They will use the program to create a sonar map of their surroundings as objects are moved in and out of the area. The students will evaluate the effectiveness of the sensors depending on the objects detected.
Challenge extensions after mapping the bat's environment could include students creating or manipulating code that:
allows their bat to exit from their cave at night
find and go to "prey" objects detected within the range of the sensors
follow "prey" objects within the range of the sensors
Challenge extensions without coding could include student research concerning:
ocean floor mapping
Mars rover
submarine sonar
military drones
adaptive or assistive biotechnology
Code Files Developed in Workshop
EV3 Code for Sonar
