A very simple, visual worksheet summarising the terminology used to describe changes of state. Students are asked to fill in 'heated' or 'cooled' to describe what has happened to a material to make it change state. Works well as a summary note for KS2 or early KS3

Activities and a short worksheet/assessment I used for my Cambridge Stage 7 Science class

Two very nice tasks to get students thinking about how particles move and interact during Diffusion. The first involves the teacher spraying air freshener and students drawing how the particles spread out. Task 2 involves leaving a gummy bear in water overnight and observing and recording any changes.

I made these booklets to guide my KS3 Science class through revising for their upcoming Progress Tests. There is one booklet for each Year group with the objectives drawn from the Cambridge KS3 Science curriculum. I have tried to make the objectives as succinct as possible and phrased them in the form of 'I can' statements. The booklets contain links to videos, interactive websites and simulations. I teach a multi-graded class (Year 7,8 and 9) so found these booklets particularly useful in helping stronger students to revise independently while I worked more closely with weaker students. For each topic, students must complete 1-2 tasks then rate themselves for each objective as red, amber or green. I suggested they use this to help establish what they need to go back and study further.
