Describing motion
\n– speed and the quantitative relationship between average speed, distance and time (speed = distance \u00f7 time)
\n– the representation of a journey on a distance-time graph<\/p>\n

Forces
\n– forces as pushes or pulls, arising from the interaction between 2 objects
\n– using force arrows in diagrams, adding forces in 1 dimension, balanced and unbalanced forces
\n– forces: associated with deforming objects; stretching and squashing \u2013 springs; with rubbing and friction between surfaces, with pushing things out of the way; resistance to motion of air and water
\n– forces measured in newtons, measurements of stretch or compression as force is changed
\n– force-extension linear relation; Hooke\u2019s Law as a special case<\/p>\n

Pressure in fluids
\n– pressure in liquids, increasing with depth; upthrust effects, floating and sinking
\n– pressure measured by ratio of force over area \u2013 acting normal to any surface<\/p>\n

Balanced forces
\n– opposing forces and equilibrium: weight held by stretched spring or supported on a compressed surface<\/p>\n

Forces and motion
\n– forces being needed to cause objects to stop or start moving, or to change their speed or direction of motion (qualitative only)
\n– change depending on direction of force and its size<\/p>\n","protected":false},"excerpt":{"rendered":"

Students estimate and measure forces, consider mass and weight and investigate elastic limits. They may study buoyancy and other balanced forces before considering what happens when forces are unbalanced. There are also materials about friction, speed and pressure calculations, and a variety of literacy tasks. <\/p>\n

The Science Grab Bags included a range of curriculum materials including worksheets, literacy materials, practical tasks, practical alternatives, plenaries, crosswords, research tasks and much more. All resources are placed in individual digital files along with separate answer files. The Premium version includes the original Word files – great for teacher editing before sharing or as a basis for student work. Approx 100+ pp in individual task files (including full separate answer files) plus spreadsheets and PowerPoints.<\/em><\/p>\n
