Feedback and error review.

Try this with Physical Sciences

1. Choose one criterion, teacher comment or mark you want to understand.
2. Compare your answer against that criterion and rewrite only the part that missed it.
3. Try the same skill on a fresh task to see whether you can apply the feedback.

Pick a starting point

• Atomic structure and the periodic table: Electron configuration, shells and periodic trends in atomic radii and valency
• Describing motion: Scalars, vectors and the equations of uniformly accelerated motion
• Conservation of momentum: One-dimensional collisions and explosions using Σp(before) = Σp(after)
• Bonding and structure: Metallic, ionic, covalent molecular and covalent network structures and the properties they explain
• The mole and reacting quantities: n = m/M, n = N/N(A), the Law of Conservation of Mass and simple stoichiometry
• Isotopes and relative atomic mass: Isotopes, mass spectra and calculating relative atomic mass from abundances
