A Understand the basis of
chemistry and scientific measurements.
1 Measure volume, mass, and density.
2 Identify equipment used in a beginning chemistry lab. (A minimum of
3 Understand and use the Scientific Method.
4 Demonstrate the process of the scientific method.
5 Use the scientific method to classify observations.
B Use the concepts of dimensional analysis, scientific notation & significant figures to solve problems.
1 Use the Metric (International) System (SI) to make measurements and in solving problems.
2 Use dimensional analysis to solve problems and perform unit conversions.
3 Use scientific notation to represent very large and very small numbers and to correctly use scientific notation in calculations.
4 Determine the number of significant figures in a measurement and to use this to correctly report answers.
5 Know the difference between accuracy and precision.
C Be able to classify matter and identify changes in properties.
1 Classify mixtures as heterogeneous or homogeneous and understand the differences between mixtures and pure substances.
2 Identify and give examples of physical and chemical changes.
D Measure and calculate energy transfers and changes.
1 Understand the difference between energy and temperature.
2 Calculate and measure energy changes.
