This resource is very handy to have in your toolbox for Years 4-6. It can be linked to shapes in mathematics, gives students a chance to do some research online and encourages them to plan and build. You can place whatever restrictions you like on them for this activity and computers are optional…Do the research as a whole class and then send them off to plan and build. The planning side is crucial if you want good results and we have found the strength competition to be very popular – hotly contested, but popular. This activity is also great for “Science Day” if your school runs one. Oh, and straws are cheap! Another bonus.
