Segment C: Significant Figures
We take you to a woodworking shop where we explain the rules for using significant figures as we work through examples.
-Explain that in science we come up with a hypothesis and perform experiments (take measurements) to decide if a hypothesis is valid or not.
-Express and explore the idea that measurement tools always come with a degree of uncertainty.
-Provide the rules for determining the number of significant figures in a number.
-Show how we handle significant figures during calculations.
-Demonstrate these rules with examples.
significant figures - the important digits in a number that express its precision.
