4th Grade Engineers

4th grade Engineers!

For the past two weeks, the 4th graders have been learning the Steps of the Scientific Method in Science class.  To demonstrate this method in action, each group designed and constructed a bridge spanning two feet across desks.  The challenge was to build their bridge strong enough so that it would hold 20 pennies in a cup  using only three pieces of paper, six straws, eight paperclips, six rubber bands and two pieces of tape.  Most designs were successful the first time.  After the first trial, students went back to the drawing board to figure out a new plan for their bridges to hold the pennies. All the students perfected their construction designs because after trial two, all the bridges held the pennies! Great job 4th Grade Engineers!
