We started an exciting new science unit this week -- bridges! I had originally planned to cover this topic with just the boys but due to a delay in resources Lily has been able to join us. Lily completed a unit on electricity at the TLA Surrey campus and as I don't have any specifics planned for her this month she's joining in. We had so much fun on Monday that we decided to invite Justin, Simon and Sina to join us for the rest of the unit.
Lily reviewed some bridge building basics with everyone while I made playdoh --one of our building materials for today.

We learning about "The Amazing Arch" today and built (or began to build) bridges from two different materials. They first made piers, beams and arches from the playdoh. These are still drying out in the oven. Then moved on to building a cofferdam from popsicle sticks (it didn't quite work out). Then onto building arched bridges with cardboard and comparing the same bridge with and without abutments.
Here is the book that we're using,
Bridge! Amazing Structures to Design, Build & Test Don't be deceived by the childish cover-- it covers the topic in depth!
