5th Grade Engineers Measure Strength of Toothpick Bridges

The 5th graders studied, designed, and built bridges out of toothpicks and glue then gathered on Jan. 5 to test their bridges' strength.  Students earned points for their bridge's appearance, "cost" of materials, and ratio between bridge weight and how much weight it could hold.  See a Photo Gallery of the students and bridges and watch a Video of the testing process.  Congrats to Janie and Per, whose bridge weighed just 71 grams but held 3 lbs.
