Intro: Scissor Linkages

ByStrawbees

An introduction to constructing linkages. Start with making 2 pairs of scissors, then to combine to build a mini mechanical arm learning about mechanical advantage. Make a small pyramid, also called a tetrahedron, to pick up. Discover the design challenge of building and improving the mini mechanical arm to pick up a weighted variety of objects.

    3-5-ETS1-1 - Engineering Design
    3,4,5
    Define a simple design problem reflecting a need or a want that includes specified criteria for success and constraints on materials, time, or cost.
    3-5-ETS1-2 - Engineering Design
    3,4,5
    Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem.
    3-5-ETS1-3 - Engineering Design
    3,4,5
    Plan and carry out fair tests in which variables are controlled and failure points are considered to identify aspects of a model or prototype that can be improved.
    MS-ETS1-1 - Engineering Design
    6,7,8
    Define the criteria and constraints of a design problem with sufficient precision to ensure a successful solution, taking into account relevant scientific principles and potential impacts on people and the natural environment that may limit possible solutions.
    MS-ETS1-2 - Engineering Design
    6,7,8
    Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.
