Set the Criteria Develop a set of criteria that you must take into account when you are designing a headlamp. Use a variety of print and electronic sources to locate information on the headlamps used by mountain climbers. Your research may include an actual example of a headlamp. Use your research to define and describe the criteria you will use to evaluate the design of your headlamp. Plan your design before you begin construction.
Planning can include a clearly labeled diagram and a set of instructions.
A good plan can save you a great deal of time and prevent wasting resources. Check the plan to make sure you have built in features that will allow you to meet the criteria or specifications of a headlamp. Carry Out the Plan Use your design plan to construct a headlamp. Test and revise your design frequently, to lead to a better product. Evaluate Once you have completed your design, evaluate if it meets all of your criteria.
