The Year 8 students have been experimenting with the fundamental forces of motion, energy and force in their Technology class. In order to get a hands on approach to engineered systems the students have designed and made working models of ancient trebuchets (catapults). The students refined their designs to gain the
maximum force and energy (velocity) from their machines, and have graphed the distances in a table to identify the most energy efficient design.
The students were invited to demonstrate the trebuchets to the Class 6 students who are currently studying the Ancient Roman Epoch.
