Cotton Ball Launcher Experiment for Edison Robots

This is a lesson designed for Edison Robots. Students will use the EdCreate kit to engineer the robot into an EdTank cotton ball launcher which represents a robot that assists in firefighting scenarios. Students will then collaborate in small groups to code a set of programs in EdBlocks to control the EdTank so that the robot will drive until it encounters the fire, stop, shoot out its water/fire retardant payload (i.e. the cotton ball) and return to the firefighting team’s base. Using the scientific process, an experiment will be designed to test whether the length of the launcher arm affects the distance the cotton ball will travel. Students will analyze data they collect to write a conclusion using the C-E-R format.
