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.
