Rules • Each student is assigned a base unit out of 3 possible ones, kg, m, s. Note that the other 4 base units, A, mol, K and cd are not given because they will be covered in later topics. • For a class of 25, the following distribution is recommended: • kg – 5 • m – 10 • s – 10 • Students will be asked to form groups when shown a Physical Quantity. Those with a negative power, e.g. the two “seconds” in kg m s–2, will have to sit/squat down. • Students who did not form a group will be ousted and the last few left in the game will win prizes.
