On Thursday March 3rd, engineer Sharon Quigley from Aecom came in to talk to our class. She talked to us about the different types of engineering and the role of engineers in our lives. It was a really interesting talk. Afterwards each group worked on the Marshmallow Challenge. Working in groups of three, we had twenty minutes to design the tallest free standing structure using only 20 spaghetti strips, one metre of string, one metre of masking tape and one marshmallow. Kristiyan, Kate and Callum's structure was the tallest at 46 cm.
