9. Measurement—A Common Language SI Prefixes SI units are similar to our money units, in which a dime is ten times more than a penny. Name the example for each of the SI Prefixes.

10. Some SI Units of Measure Measurement—A Common Language

11. Compare and Contrast Name the similarities and differences of mass and weight. Measurement—A Common Language

12. Volume of Liquids Measuring the volume of liquids and rectangular solids requires different methods. Measurement—A Common Language

13. Densities of Some Common Substances Knowing the density of an object helps you predict how it will float and identify what it is made of. Measurement—A Common Language

14. Temperature Scales Zero on the Kelvin scale (0 K) is the coldest possible temperature. It is called absolute zero. What is the boiling point and what is the freezing point on the Celsius thermometer? Measurement—A Common Language

15. Mathematics and Science Accuracy and Precision In a game of darts, accurate throws land close to the bull’s eye. Precise throws land close to one another. Where would darts land in the situations described on boards C and D?

16. Mathematics and Science Significant Figures Suppose you are tiling a bathroom. You might estimate that the tile is 5.3 cm long. The measurement 5.3 cm has two significant figures, or sig figs. You are certain of the 5, but you have estimated the 3.

17. Mathematics and Science The percent error in the calculation of the density of copper was 5.04%. Percent Error The experimental density of copper is 9.37 g/cm 3. The true value is 8.92 g/cm 3. To calculate the percent error, use the following formula and substitute.

18. Mathematics and Science Hognose Snake Egg Data We can use math to analyze the data in the table about the number of hognose snake eggs in seven nests.

19. Mathematics and Science Collected Data What might be an unknown variable that could have affected data?

20. Mathematics and Science Think Like a Scientist How and why are the number of sea turtle nests in Florida changing?
