This very short week, we only had a chance to look at proton numbers and mass numbers and what they tell us about elements, as well as isotopes.
This week we finished off separating techniques with a final look at how to separate two immiscible liquids, followed by the start of a new section on atomic structure
This week we concentrated on Fractional Distillation as a separating technique for alcohol and water, crude oil and atmospheric gasses.
This week was all about crystallisation, making crystals and physical versus chemical changes
This week we looked at criteria of purity in chemicals, and various methods of purification, including filtration and crystallisation
This week we learned about seperating mixtures using a technique called paper chromatography. We were able to do an experiment at home.
Kinetic molecular theory as evidenced by diffusion and Brownian motion, and Quantities and symbols of measurement.
Kinetic model of matter, heating and cooling curves
This week was all about the particulate nature of matter, including vocabulary about phase change. Focus Syllabus C1.1.1 to C 1..1.3
Year 7 - sampling techniques, adaptations, Year 8 - drugs and addiction, Year 9 - population graphs, the greenhouse effect and the hole in the ozone layer, Year 10 - Brownian motion, heating and cooling curves, Year 11 - d.c.…
