__ **Welcome to the Room 3 page about Auckland Harbour Bridge.** __ In our Science fair, we are investigating how to develop and execute our own experiments. We are the proud winners of a competition celebrating the 50 years of the Auckland Harbour Bridge because we are studying a bridge problem as part of our Science fair.

__**The challenge;**__ Design and construct a bridge which can span a 20cm gap between 2 tables, and be at least 4cm wide. Use only spaghetti and glue. The bridge will be tested for strength using weights which will be hung from it. Credit will be given for design, quality of construction, and style.

Your initial plan must include 2 initial design drawings, from 2 different views, of your intended bridge. It must pass a judge's inspection before progressing. Judges will be looking to see if your bridge looks safe, and meets the rules of the competition. It should be labelled with measurements in order for you to calculate the quantity of spaghetti you will be using. Bridges found to have used more than their 20 pieces of spaghetti will be disqualified. __**You will be given;**__ -20 pieces of spaghetti -Unlimited glue //No additional building materials are allowed.//
