  1. 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”

  2. Notes from Prelab Characteristics of Life/Cell Theory recollections • Cells come from cells • Cells are the smallest unit of life • Metabolizing (respiring, growth, energy transfer via enzymes) • Reproducing • Self-movement as a response to a stimulus ____________________________ Theories as to origin of life • Panspermia- came from across the universe (evidence: amino acids, fossils) • Chemical evolution- primordial soup (requiring: energy transfer, polymerization, reproduction, information molecule)
