In this learning sequence, students explore frictional forces. They investigate how friction changes with different contact surfaces in wet, dry and icy conditions, and the effect this has on braking. Finally they apply this learning to the real-world situation of tram travel, and explore why sand is used on tram tracks ...

• TLF-IDM016761

Students use this resource consisting of five slides with diagrams, written explanation and voice-over to understand how a fuse protects a circuit and learn some uses of resettable circuit breakers. There is a two-question quiz and a summary slide.

• TLF-IDL52

Investigate braking efficiency of cars and trucks by testing stopping distances under controlled conditions. Test effects of vehicle type, tyres, road surface and weather conditions. Choose driving speed, then apply brakes and compare stopping distances. Estimate distances from target markers. Answer questions about antilock ...

• TLF-IDM025073

In this learning sequence, students explore a simple particle model for matter, heat energy and thermal expansion. They apply their learning to the context of expansion and contraction of rail lines and investigate ways that this is mitigated in real situations involving rail lines. They subsequently explain this to young ...

• TLF-IDM025074

In this learning sequence, students determine improvements they would like to see in public transport. They research ways of suggesting improvements to public transport authorities and other decision makers, and prepare letters and emails for this purpose. They prioritise future improvements and develop arguments to support ...
