Bridge Bonanza

Activity Language
Time Needed for Activity
Learn about strong and stable structures by building and testing bridges.

Students learn about strong and stable structures by building three different kinds of bridges and testing their load limits. The take-home message is that triangles are strong and stable shapes.

What You Need

Materials:

  • Mini marshmallows (can’t reuse)
  • Toothpicks (can’t reuse)
  • Small zip bags
  • Straws
  • Clear tape (some used to prep supplies, plus one roll for each pair of students)
  • Embroidery floss or thin string
  • Pennies (or other small objects that can be added one at a time to test load-bearing limit of bridges)
  • Plastic cups, string/ribbon, large paper clips
  • Pictures/slideshow on a USB stick
  • Optional: large marshmallows and spaghetti strands or skewers for demo cubes and pyramids (or appropriate building toy)

Discovery

What's happening?

These activities were developed for the Grade 3 Science unit Understanding Structures and Mechanisms: Strong and Stable Structures Ontario curriculum. The take-home message is that triangles are strong and stable shapes and are used in the construction of many different kinds of structures. The students focus on building bridges and testing them for load-bearing capacity. They build beam, truss and suspension bridges and learn that triangles add strength and stability.

Investigate Further

The introductory activity building cubes and pyramids with mini marshmallows and toothpicks and possibly building and testing the beam and truss bridges made with mini marshmallows and toothpicks could be done in a shorter time frame. This easy building activity emphasizes the strength and stability of triangles over squares.
