Chemistry Part 1 will explore many aspects within the subject of chemistry. Students will begin by investigating matter, atomic structure, and the periodic table. The learners will then explore the role of electrons with respect to ionic, metallic, and covalent bonding. Students will also demonstrate the ability to name and to write formulas for ionic compounds, molecular compounds, and acids and bases. Finally, students will analyze mole-mass relationships and mole-volume relationships. In addition to virtual experiences, the lessons in this course will provide students with hands-on lab experience through various inquiry activities and mini-labs that can easily be performed in the home. These experiences encourage skills necessary for critical thinking. This course includes a virtual chemistry lab CD.
