This month students will be investigating the mathematical aspects of chemistry. Students will learn the importance of significant figures and metric conversions. They will be making measurements, such as mass, volume, and density. Students will also learn how to determine whether their measurements are accurate or precise. We will be making conversions between the standard system of measurement used in America and the SI system used by the scientific community. We will perform labs in which we use a metric recipe to make bubble soap. We will also make a density column. The second half of the month, students will start learning about the submicroscopic world (atoms, ions, isotopes, etc.) We will learn about the history of the atomic theory and perform a fun alchemy lab, in which we will create silver and gold-colored pennies. Students will also learn about the structure of an atom (protons, neutrons, and electrons), and how ions form.
