4-H Robotics: Engineering for Today and Tomorrow
The 4-H Robotics: Engineering for Today and Tomorrow curriculum is designed in three tracks. In Track 1 (Virtual Robotics), youth can participate using the virtual activities on-line or via a DVD-ROM. Track 2 (Junk Drawer Robotics) encourages youth to use household materials to engineer robotic designs. In Track 3 (Platforms) youth with access to specific educational robotics platforms (Lego, VEX, Robotix, etc.). More information on this national curriculum may be found at http://www.4-h.org/resource-library/curriculum/4-h-robotics/.

Junk Drawer Robotics
The Junk Drawer Robotics curriculum engages middle school youth in understanding scientific concepts and processes, the engineering design process cycle, and technology creation and building. Junk Drawer Robotics provides youth these experiences by working with household items to complete simple design challenges. These robotics activities emphasize science, engineering and technology process skills, cross-age instruction (teenagers-as-teachers), the experiential learning cycle, and small group learning. Activities are designed to be led by an adult or teen facilitator.
Level 1: Give Robots a Hand
In this level youth will be exploring and learning about robot arms. The arm is one of the most useful and imitated parts of the human body. It is flexible with joints; shoulder, elbow, wrist, that allow it to be placed in many positions to reach and grab. The hand with its fingers and thumb can grab, hold, pick up, and more. Designs for robot arms can allow a robot to be used to grab, lift, move, or position items into a machine, to control a spot welder, or to assemble parts for an item.
Mobile robots make up an array of applications allowing robots to go and do things in locations and situations that humans would not like or could not go. Mobile robots can go into dangerous situations, can fly, go under water, traverse remote areas or planets, carry instruments and sensors, and much more. In this level youthwill explore legged, wheeled, and underwater robots. We will explore friction, basic electrical power and motors, engineering constraints, gears systems, and buoyancy.
Level 3: Mechatronics
For greater control and usefulness, robots merge mechanical objects with electronic components. In this level, youth will explore components of electronic devices and basic programming elements. Various sensors will be used to help robots explore the world and react in programmed control.
Each model contains a number of activities in these phases:
|To Learn: Science is finding out how things work. These activities emphasize exploration and form the foundation upon which youth build conceptual understanding.|
|To Do: Engineering is designing something to work from what you discovered. These activities build upon the knowledge gained in the exploration phase related to the concepts in the module. Youth are presented with a design problem and work together to design and plan a solution.|
|To Make: Technology is using tools and processes to make something work. These activities
allow youth to build and test their design while solidifying their understanding of the concepts.
