Work sample Year 8 Science: Bouncing ball

This work sample demonstrates evidence of student learning in relation to aspects of the achievement standards for Year 8 Science. The primary purpose for the work sample is to demonstrate the standard, so the focus is on what is evident in the sample not how it was created. The sample is an authentic representation of ...

Physical world – design and production investigation

In this investigative task, students explore how rolling objects are affected by changes in forces including stopping, starting, rolling faster and slower and in different directions. They explore the effects of force on objects by designing a marble push course. Using a straw to exhale (push) air, students manoeuvre a ...

Physical world – design and production investigation

This investigative task focuses on energy transformations between kinetic (movement), electric and light energies. Students design, test and evaluate a system that uses energy transformations to meet an identified need. They work in pairs to design and construct a wind turbine tower that demonstrates how different types ...

All about engines

What does 'horsepower' really mean? And how do engines work? Join Luke and Abhi from MIT to find out! As Abhi explains, engines produce power by forcing a mixture of fuel and air into a tight space and then burning it. Piston engines and turbine engines do this in similar, yet different ways. After watching this video, ...
