Just a nice and relaxed post for the weekend. I came across a few sites that had some really impressive bridges from around the globe. Some are still under construction. Take a look at them and share them with your kids if you are keen. My class will have a look at these Monday and discuss some of the purpose and features of them. Then we'll create some straw and pin bridges over a 50cm span and see which team can make the one that will hold the most amout of weight on it. See how you go.
