    4. Use the K'nex directions to build the door. (take pictures along the way to show progress in building)
    5. After you built the door, use the remaining pieces to customize your door. Why did you add those elements? What was gained by your customization?
    6. Label  the fulcrum, resistance, and effort on the door

    RESEARCH: 
    1. What is a lever?
    2. Research the terms as they relate to this engagement: effort, resistance, fulcrum, work, load, and force.  
    3. Provide a sketch in your Field Notebook explaining each of the terms.
    4. Provide a real world example for each term of how they are used in everyday life.

    CRITICAL THINKING:
