Today our Year 7 students have been applying their physics knowledge about levers and pulleys. In a series of experiments, they’ve observed how different pulleys, levers and fulcrum positions alter the effort needed to lift a range of heavy loads—from a sack of filled water bottles (approximately 18kg worth) to their teacher, Mr Boman (70kg)! Due to the force multiplier lever in use, each load was reduced by at least half each time, much to the surprise of the students. What a wonderful way to s
