Completely revised in Dec. 2024: improved questions, layout, and answer sheet. Further differentiation. Please ensure you can access the video before you get this resource. Find the film by searching YouTube’s Tangwaap channel for Scientific Eye: Salty Water. Many other channels also host the video.
The film covers: a marine aquarium; solutions; uses of salt including biological importance; formation of Cheshire Rock Salt deposit; human history of salt; marine salts, the Dead Sea; buoyancy; desalination for salt production, and desalination for fresh water at sea.
15 questions for the 19-min film. Now differentiated THREE ways! All versions look similar, but “B” version has subtle clues, and “C” version asks pupils to circle the right answers from a choice of three, allowing pupils with literacy difficulties to access the work. Questions right up to the end, no slack time. Answer sheet. Very easy to mark. .doc & .pdf for all files. Two separate links to the film on all sheets.
