YEAR 9 STEM

Engineering Challenge design and build the strongest, most cost-effective bridge  

The year 9 STEM class were given the engineering challenge to design and build the strongest and most cost-effective, self-supporting bridge that spans a 30 cm gap and can carry up to a 250g load.

Each group of students were given only 1 x pack dry spaghetti, 1 x glue gun + glue sticks and 1 x package rubber bands. Each team first planned their design and drew a scale drawing. Each final bridge was also costed. 

Congratulations to the team (Niamh True, Lexie and Tahli Younan, and Sava Postnikov) who designed their bridge based on the Baltimore Truss Bridge and also the Camelback Truss Bridge. 

Their final spaghetti bridge was a masterpiece in engineering, successfully spanning a 30cm gap and able to withstand nearly 11kg of weight. 

Well done!
