Since we are starting a new section about electricity in chemistry, our lessons this week focussed on electron flow, electron position in various types of structures, and electrolysis of ionic salts.
This weeks lessons focussed on rates of diffusion , a summary of particles, and an introduction to how electricity works.
Since its such an important topic, this week covered mole calculations in gases and in titrations, as well as a look at SI units of measurement in chemistry
This weeks lessons were all about moles and mole calculations of various sorts.
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
So in this short week, we started the biology section by looking at how plants make food, and how water travels through a plant
