This video contains all the required practicals for Physics Paper 1. For combined and separate scientists, this includes: 1) 0:00 specific heat capacity (5:05 difficult method), 2) 7:32 how the length of a wire affects resistance, 3) 10:57 how adding resistors in series or parallel circuits affects resistance, 4) 14:23 current-potential difference (IV) graphs, 5) 18:43 density of regular and irregular objects. For separate scientists only, there is also a required practical on heat insulation (20:33).
