BLOCK 2 Questions to consider • Definition/Illustration – Spectrum of solubilty, insoluble but if shaken, emulsifies=droplets in solvent • Influencing (IV) factors – Heat – Type charge on chemical – Concentration of chemical/amount of water – Acidity/alkalinty (in baseline/guided expt) – Mixing/shaking/swirling etc. • Things to measure/observe (DV) – Number/frequency – density – Size in microscope FOV • Chemical explanation – Interaction between +/- charges (diagram) complex – Reduction of hydration around colloidal particles (research the terms) simple – ? About role of water • Connection to origin of life question – Shows a model for possible genesis – Share feature with present and original “cells”
