Year 4

Access all areas

Students are introduced to concepts about forces, including friction, gravity, magnetism and buoyancy, in a practical engineering challenge where their apply their learning to design or improve an accessibility vehicle that can traverse diverse terrains and weather conditions.

'Access all areas' IS ONE OF OUR NEW TEACHING SEQUENCES FOR V9

Launch

Lesson 1 • Portable packages

Students connect to the content and context of the sequence by transporting a package, which must always stay in contact with the ground, across different surfaces. They describe how the object moved and record their observations using prior knowledge about forces.

Lesson 2 • Feeling friction

Students explore friction by investigating the amount of force required to pull a shoe across a surface.

Lesson 3 • Gravity’s grasp

Students explore how the force of gravity pulls things towards the Earth, and how objects with more mass require more force to move.

Lesson 4 • Magnetic movement

Students measure magnetic strength by determining how far apart a magnet and magnetic material can be before the magnetic force is too weak to cause movement.

Lesson 5 • Floating free

Students observe how liquids exert an upward force that enables objects to float. They then test how different raft shapes affect buoyancy by measuring how much weight each raft can hold before sinking.

Lesson 6 • Reliable rollers

Students explore toy rollers made and played with by First Nations children in inland Australia, and investigate how they can be changed to suit specific conditions.

Lesson 7 • Access allowed

Students consolidate their learning by designing an accessibility solution that facilitates access to difficult terrain by using and/or overcoming forces. They represent what they know about forces by drawing a labelled/annotated diagram of their accessibility solution.

Curriculum and syllabus alignment

Achievement standards

By the end of Year 4 students identify forces acting on objects and describe their effect. They explain the role of data in science inquiry. They identify solutions based on scientific explanations and describe the needs these meet.

Students pose questions to identify patterns and relationships and make predictions based on observations. They plan investigations using planning scaffolds, identify key elements of fair tests and describe how they conduct investigations safely. They use simple procedures to make accurate formal measurements. They construct representations to organise data and information and identify patterns and relationships. They compare their findings with those of others, assess the fairness of their investigation, identify further questions for investigation and draw conclusions. They communicate ideas and findings for an identified audience and purpose, including using scientific vocabulary when appropriate.
