Divide into teams of two (2)

Review the requirements

Discuss a solution and create a sketch of your design

Build a model of your design with given materials

Test your model

Outline and Procedures

+Robot Arm

Discuss and agree upon a redesign If needed after testing, or to enhance the previous design

Rebuild your robot arm

Retest your model

Answer reflection questions as a team

Redesign after testing

+Robot Arm

What was one thing you liked about your design? What is its main weakness?

What is one thing you would change about your design based on your experience

Are there algebraic and physical principles that can be applied to this activity?

How would you modify the instructions to create a better experience for the participants?
