Chapter 1 - The Science of Chemistry
chemistry is the study of matter and itschanges,water is an essential chemical,matter has mass, volume, and pressure,accuracy does not mean precision,we use scientific notation to refer to verylarge or very small numbers.
How can a seedling become a tree?Is a precise result necessarily accurate?Is 0.012 the same thing as 1.2 × 10 ?
1B: Volume in ChemistryStudents learn how to measure volume using agraduated cylinder. They also observe achemical reaction by adding drops of bleach tosolutions containing food coloring, thencalculate the percent by volume of bleachneeded to remove each color.
1C: Mass in ChemistryStudents learn to measure the mass of solidsand liquids on a digital balance. Liquiddetergent is then added to a mixture of waterand oil. Students propose a hypothesis toexplain their observations.
1D: Dimensional AnalysisThis is a fun way for students to practice usingconversion factors. They manipulatedimensional analysis cards that show them howto cancel units when they do conversions.
