Live MS
Physical Science, Part One

In this course, you will study the matter and forces that God used to create our universe. Students will watch a recorded lecture before class in this “flipped classroom” and bring assignment questions and ideas to the interactive classroom.

Total classes: 13 live classes plus pre-recorded lessons, which must be viewed before the live class each week.

Prerequisite: 7th-grade math, previous or concurrent

Suggested grade level: 7th to 9th grade

Suggested credit: One full semester of Physical Science

Special Notes: This is a 3-part course. Part One is a prerequisite for both Part Two and Part Three. Students are expected to sign up for Part Two OR Three in the Spring. Due to the popularity of this course, it is offered twice (on the same day). Choose the time that works best for you and your homeschool. There are weekly pre-recorded lecture lessons in addition to the 13 live classes. One week the live class may be changed to a pre-recorded class.


This is a ‘flipped’ class. Students will be required to watch the recorded lecture before coming to the live class. The live class will be in a discussion (question and answer) format based on the lecture. We will study the matter and forces that God used to create our universe. Completion of this course (Parts One and Two) is excellent preparation for high school chemistry and physics.

Materials and Homework

Course Materials and Technology:

1. Text: Holt Science and Technology: Physical Science (Holt, Rinehart, and Winston, 2007) ISBN: 0-03-046228-2. We recommend buying used. (www.amazon.com/exec/obidos/ASIN/0030462282/catholictreas-20).

NOTE: The teacher will provide the 2004 edition of this text free online to the class. It is missing some information. Everything missing from the text is available in the class recordings and accompanying slides. This is an acceptable, but not ideal, alternative to the textbook.

2. A calculator

3. A computer with a working microphone. (This is an interactive class; microphones are mandatory.)


  • The pre-recorded lecture videos must be viewed before the live class each week.
