Change to an object’s motion is caused by unbalanced forces, including Earth’s gravitational attraction, acting on the object (ACSSU117)

Elaborations
• investigating the effects of applying different forces to familiar objects
• investigating common situations where forces are balanced, such as stationary objects, and unbalanced, such as falling objects
• investigating a simple machine such as lever or pulley system
• exploring how gravity affects objects on the surface of Earth
• considering how gravity keeps planets in orbit around the sun

### Electromagnetic Simulation (sk-Intel)

In this resource students explore how an electromagnet works in real life. They can then apply their learning in an electromagnetism game by changing the magnetism of a scrap lifter in a scrap yard and removing various amounts of scrap. The resource demonstrates the connection between the power applied, the number of coils ...

### Measuring Speed (Simulation)

Students use this resource consisting of a webpage with diagrams of three cars that students can vary the speed at which they are travelling. They can calculate the time to travel 3000m and then observe the cars as they travel the distance. This demonstrates how to work out the speed of a moving object and how to make calculations ...

This resource contains a materials and instruction list and brief explanation for students about the process of separating ink mixtures using paper chromatography.

### Understanding Magnets

In this simulation students select an object made of one of two materials (either iron or aluminium) and use magnets to guide the object through a maze. Engages students while they learn that aluminium is not attracted to magnets but iron is.

### experiMENTALS: Magic rocking candle

This resource contains a materials and instruction list and brief explanation for students about the process of burning both ends of a balancing candle. This activity is most likely to be done as a teacher demonstration for safety and classroom management reasons, particularly at primary school level.

### Pivots and Levers: animation

Students use this resource consisting of one page with a diagram of a lever whose length can be varied. A weight is then applied to the lever and students can see whether the force was sufficient to lift a crate. This demonstrates that forces can cause a lever to turn about a pivot and that the turning effect of a lever ...
