Rumour has it Ms Fisher has been torturing students for her own amusement...the truth is Ms Fisher is torturing the kids for their own good...educationally AND also for her own amusement. To start with, she took away their chairs!
No, really this is a prac for Ms Fisher's Year 8 Science class in their Body Systems unit of work and what they're testing is muscular endurance with 'wall sits'.
Another excellent torture test endurance prac was to see how long students could hold 2kg weighted bottles with their arms straight, and out at 90 degrees; class champions were Nikki and Lochlan, as seen below.
All in the name of fun science and education, right Ms Fisher?
