Pre-Chemistry Course Overview

This Pre-Chemistry homeschool course for middle school and and high school students will focus on introducing students to the basic structure of elements and how elements combine to form compounds. Upon completion of this middle school course, students will be familiar with the Period Table, the structure of an atom and the mechanism involved in ionization and compound formulation.

Everything you hear, see, smell, taste, and touch involves chemistry and chemicals. And hearing, seeing, tasting, and touching all involve intricate series of chemical reactions and interactions in your body. With such an enormous range of topics, it is essential to know about chemistry at some level to understand the world around us.

Course Reviews

“My daughter just finished Mr. Leingang’s PreChemistry class and loved it! I highly recommend!!” ~ Erin

“I took Pre-Chemistry in fall, 2016, with Mr. Leingang during my seventh grade school year. He was my first online teacher. I liked him because he made us work hard and expected the best from us. He could make complex ideas very simple. He likes kids, but does not tolerate misbehavior. He himself works hard at teaching us, and it motivated me to work hard for him. I would love to take another class with him because he’s the best science teacher ever!” ~ Joshua

“My son and daughter (8th and 9th grade) took your Pre-Chemistry class this fall. It was NOT easy, however, they learned SO much and you made them work. You have high expectation and the kids learn to respect you and DO the work! I was so impressed with how they were able to rise to the challenge and with the level they were learning. This course is excellent! I love the book, the labs, the tests and homework. I also appreciate how quick you are with keeping the kids on topic with chat! You are an excellent online teacher! Can’t wait for the kids to take High School Chemistry with you next year!” ~ Suzy

Chris Leingang

The desire to be a teacher was birthed in Chris Leingang during his 8th grade year. After graduating high school, Chris entered college with that desire still burning inside. In 1996, Chris graduated from Portland State University with a B.S. in Science with an emphasis in Chemistry and Physics and then went on to graduate from Concordia University, Portland with an M.A.T. in Secondary Education in 1998.

Mr. Leingang's teaching experience spans both middle school and high school in both the private and public sector. He has had the opportunity to teach a wide variety of subjects including General Science, Physical Science, Chemistry, Physics, Forensic Anatomy and American Government. Chris was later called into full-time Christian ministry with Lutheran Brethren Youth Ministries, where he led teams of young adults as they worked in church-planting and outreach.

Mr. Leingang's passion for teaching had not left but had been refocused on ministry, missiology and church leadership. As with most teachers, his passion for teaching is coupled with a passion for learning. Hence, it was no surprise, when in 2002, he enrolled in seminary.
