Highlights from the Powerpoint Presentation
We started with a Powerpoint presentation which discussed the definition of a bridge, different types of bridges, bridge construction, the strongest geometric shape for a bridge (the triangle), the types of triangles generally found in bridges (equilateral & scalene) and how bridges actually work (compression and tension).
Whew! A lot of information to digest in 30 minutes! This information set the stage for the “Truss” project which involved building the strongest bridge possible with sticks, glue and electric cable ties.
Here are a few slides from that presentation:
Videos of how bridges work:
Popsicle sticks (4-1/4″ – 6″) – at least 200 sticks per bridge
Craft glue, glue guns and/or book glue
Electric cable ties (can be found at Home Depot for a few dollars)
