    Intro: Scissor Linkages

    Strawbees Team

    Explore creative inventions made from scissor linkages. Discover the design challenge of building and improving a small mechanical arm to pick up a weighted variety of objects. 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.
