structures and mechanisms
  • Column Challenge!

    How strong is paper? Fold and bend paper to see if different shapes lend more strength to a material. Investigate why columns are an effective building element for strong and stable structures.


    MATERIALS

    • 3 sheets of 8 ½” x 11 paper (you can recycle scrap paper!)
    • Masking tape or scotch tape
    • A load (a can of soup)

  • Making Materials Stronger!

    Humans have a knack for taking simple materials and making them stronger, more durable, or more resilient, just by making simple changes to their shape. Find out how you can make changes to strengthen materials that you can find at home!


    MATERIALS

    • Paper towel
    • Something heavy-ish with a handle that will not make a mess if it is dropped, such as a small bucket filled with objects or a tightly closed filled jug or water bottle with a handle.
    • Paper (recycled office paper is fine!)
    • String or ribbon
