1. Measurements and Experimentation (i) Estimation by orders of magnitude of size (length, area and volume), mass and time. Order of magnitude as statement of magnitude in powers of ten; familiarity with the orders of magnitude of some common sizes (length, area and volume), masses and time intervals e.g. idea of, mass of atoms, bottle of water, planets, diameter of atom, length of football field, inter stellar distances, pulse rate, age of earth etc. (ii) International System of Units, the required SI units with correct symbols are given at the end of this syllabus. Other commonly used system of units fps and cgs. (iii) Measurements using common instruments (metre rule, Vernier calipers and micrometer screw gauge for length, volume by displacement using a measuring cylinder, stop watch and simple pendulum for time, equal arm beam balance for comparison of masses).
