Students use ultrasonic sensors and LEGO© MINDSTORMS© NXT robots to emulate how bats use echolocation to detect obstacles. They measure the robot's reaction times as it senses objects at two distances and with different sensor threshold values, and again after making adjustments to optimize its effectiveness. Like engineers, they gather and graph data to analyze a given design (from the tutorial) and make modifications to the sensor placement and/or threshold values in order to improve the robot's performance (iterative design). Students see how problem solving with biomimicry design is directly related to understanding and making observations of nature.
This is an activity to help students create characters for narrative writing or creative writing. Some students struggle to develop a character for a story and therefore creative writing becomes frustrating for them. This is a great way to help students think about their character with more depth.
Prince EA has created a series of YouTube videos including "I JUST SUED THE SCHOOL SYSTEM !!!" "Sorry Future Generations" "I am NOT black, you are NOT white" that addresses teaching methods, future environmental issues, personal opinions, and motivational opportunities for students to observe.
Prince EA uses a lyrical presentation that captures the attention of viewers by the use of "Slam Poetry" choreographed with background music.
