Middle School Chemistry

Course Description

This complete middle school chemistry course covers all of the major concepts taught across most schools in North America and prepares students for future chemistry courses. This course is unique as each topic will focus on what happens on a molecular level, allowing students to gain a strong understanding of the basics of chemistry.  A solid background in these topics will allow students to understand more complex topics of bonding and chemical reactions in subsequent courses.

Unlike other survey courses, this chemistry course is designed to allow the student to gain insight into the behavior of atoms and molecules in each state of matter and under different conditions.  In learning introductory chemistry material in this way will allow students to have a solid understanding of the concepts they will need for high school chemistry. 

For Pennsylvania learners, this course covers all of the chemistry standards for grades 6, 7, and 8.  The course also covers the physics standards on the topics of heat/heat transfer and energy. This course is also applicable to science students in the following states: Alabama, Alaska, Arizona, Arkansas, California, Colorado, Connecticut, Delaware, District of Columbia, Florida, Georgia, Hawaii, Idaho, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Minnesota, Mississippi, Missouri, Montana, Nebraska, Nevada, New Hampshire, New Jersey, New Mexico, New York, North Carolina, North Dakota, Ohio, Oklahoma, Oregon, Pennsylvania, Rhode Island, South Carolina, South Dakota, Tennessee, Texas, Utah, Vermont, Virginia, Washington, West Virginia, Wisconsin, Wyoming.

The course consists of 29 content rich video-lessons, 10 exercise and lab review or set-up videos, worksheets, note sheets, quizzes, tests and additional materials and resources which parents will have immediate access to upon purchasing this course. This course includes a number of lab activities to allow students to have hands-on experience with chemistry.  Each of the labs requiring materials uses items that could be found around the home or purchased easily and cost effectively.  Any lab requiring materials that students will likely not have available are done as demonstrations or through videos.

Course Goals

Upon course completion, students will be prepared to move on to higher level chemistry courses. Students will have a solid understanding of the periodic table, bonding, states of matter and changes to those states on a molecular level, conduction, and density.

I have loved science and nature for as long as I can remember. I enjoy passing on this enthusiasm and interest for science to my students and my own children. I have taught at the middle school level for 16 years and the elementary level for 2 years. My teaching background includes environmental science, life science, physical science, gifted education, and graduate-level education courses. I have also taught at a nature center where I got to work with a variety of animals including snakes and birds of prey. I coached a middle school Science Olympiad team for 10 years and high school volleyball for 6 years.
