Union High School, Graaff Reinet, grade 7s are learning about natural and man-made structures in Technology this term.
Earlier this week, using spaghetti and marshmallows, students experimented with different structures to determine which
ones are able to handle the greatest amount of load.

This experiment helped them to further understand the effects that compression and tension forces have with respect to the strength of structures. Spaghetti cannot hold much tension or compression; therefore, it breaks very easily.

Marshmallows handle compression well, but do not hold up to tension.

“At the Union schools, we are thankful for small class sizes which affords teachers the opportunity to successfully conduct these experiments,” said Mariette Burger, a spokesperson for the school.

“Teachers are able to be actively involved with everything the learners do, which, in turn, results in increased participation and better communication between the teacher and the learners.”
