- - - - do not time first few oscillations as they are irregular and do not sing along the same plane
      - do not displace pendulum at a large angle , the angle should be 5 degrees or less to minimise effect of air resistance
      - time 20 oscillations or more and calculate average timing to reduce significance of human reaction time in stopping the stopwatch
- - - - square :length x breadth
      - parallelogram : base x height
      - trapezium : 1/2 x h x sum of parallel sides = (a + b/2)
      - circle : π x r2
    - - count all squares that take up at least 1/2 a square
      - calculate area of 1 square
      - area = number of squares x area of one square
  - - - sphere : 4/3 π r3
      - cone : 1/3 π r2
    - - v1 - v2 = volume of object
