This week's Science Saturday had us building bridges using popsicle sticks. And since the theme is "science", the bridges had to be structurally sound and not just pretty.
The specifications were that the bridge had to span a space of 14 inches and had to be made using no more than 45 popsicle sticks.
The first task was designing the bridge on paper and then assembling the popsicle sticks, using LOTS of hot glue. Jamie drew out his design and then helped to modify as we glued it together. To strengthen the joints, small holes were drilled and short pieces of paper clips were inserted.

Civil engineers of the future?
After everyone was finished building their bridge, it was time to test their strength. Two bridges were set up, side by side, and weights were added until one bridge broke. Another bridge was set up with weight equaling the bridge still standing. The final two bridges belonged to Jamie and Parker and Parker's bridge was the strongest. Jamie's bridge came apart at one of the joints, but otherwise held up. Parker kept adding weight to his bridge and it slipped off of the stool but never broke!
and the winner is...(I took my mom's camera with me to Science Saturday to take pictures but NONE of my batteries were charged...UGH!!! Had to settle for using the camera on my cell phone. It does an OK job but, I really need a new camera!!)
