Vocabulary

Motion Capture – “Motion capture, or mo-cap, is a process of digital recording of people or objects’ movements.” Robots use motion capture systems to measure their pose in 3D space. – Teslasuit (HS)

Microcontroller – “A microcontroller is a ‘simple computer’ that runs one program in a loop. They are designed to perform a single, specific task.” – Adafruit

Motor – Direct current (DC) motors are a type of electric motor that provides efficient constant rotation. This is in contrast with servo motors that offer precise positional control with limited range of motion. DC motors use the interaction of magnetic fields and conductors to convert electrical energy to mechanical energy for rotation. – SeeedStudio

Activities
NameGrade RangeResourcesDescription
Cleaning the Ocean3-5Requires WeDo RobotDesign a LEGO prototype of a device that could help remove plastic waste from the ocean.
One World Ocean3-5$0.50/groupStudents learn about ocean currents and the differences between salt and fresh water.
Navigation Unit6-8Varies24 activity unit that explores the basics of navigation including relative and absolute location, latitude, longitude, cardinal directions, maps, and compasses. Activities can be done independently.
Build a simple motor6-12$10/groupBuild a simple electromagnetic motor
Designing Clay Boats6-8$4/groupStudents use modeling clay to design and build boats that float in water with the objective of holding as much weight as possible. Topics such as buoyancy and density are explored.
Using linear equations to guide space travel8-10$0Students act as aerospace engineering teams as they create linear equations to guide space shuttles safely through obstacles.
Build a SeaPerch Naval Remote Operating Vehicle (ROV)7-12~$150/groupSeaPerch is an aquatic robotics competition. You can build your own ROV with this manual. SeaPerch also provides lots of extension activities with Standards mapping.
