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

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

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?
