Scientific method- It is the logical or systematic approach in solving problems.Steps:1. State the problem2. Formulate the hypothesis3. Test the hypothesis4. Gathering the data5. Analyze the data6. Drawing the conclusionAssignment:Define: a) significant figures b) Scientific NotationGive the rules of significant figures & writing down numbers on their scientific form.Answer:a) Significant figures: are digits that are known with certainty.b) Scientific notation: is a combination of two numbers. The first number is a decimal number between 1 and 10, called exponent, is a power of ten.2. Rules of significant figures:1) all nonzero digits are significant.2) between two nonzero digits are significant.3) Zeroes to the left of the first nonzero digit are not significant.4) If a number is greater than 1, all non-zeros to the right of the decimal point are significant. If a number is less than one only zeros at the end of the number and the zeros between 2 non-zero digits are significant.5) the zeros immediately to the left of an unexpressed decimal point are not significant.Scientific Notation: it follow the formula /m x 10^n/ where m consists of one or more significant figure digits which are equal to or greater than one but should be less than ten.
