This resource includes a 50-slide PowerPoint presentation, guided notes and many differentiated worksheets/homework assignments on the topic of PRESSURE. By the end of these lessons, pupils will know that: 1) pressure exists on surfaces, in air and in liquids. 2) pressure is measured in Pascals (Pa) 3) on surfaces, pressure is calculated by dividing force by area. 4) pressure is smaller when a force is applied over a big area because the pressure is spread out over a big area. 5) pressure is bigger when a force is applied over a small area because the pressure is confined to a small area. 6) atmospheric pressure decreases with height, 7) liquid pressure increases with depth. 8) upthrust effects floating and sinking 9) hydraulics is an application of liquid pressure (qualitative and quantitative) I hope you find this resource useful. Thank you.

This resource is broken up into 2 parts. These 2 parts covers many of the important models of the atom. From Democritus and Dalton to Thomson and Rutherford. Part 1 includes 31 slides that covers the early models of the atom. This includes Democritus, Aristotle, and John Dalton and Dalton's atomic theory. An interactive quiz to review the topic is included at the end of the lesson. Part 2 is a highly visual 57-slide powerpoint. These activities engages learners to rediscover JJ Thomson's cathode ray tube experiment and visualise the "plum pudding" model of the atom. The second half details Rutherford's gold foil experiment and the discovery of the nucleus. A crossword puzzle and summary sheet to revise both Part 1 and Part 2 are also provided.
