See why so many parents choose Journey Homeschool Academy for hands-on, faith-based science.
The thought of taking Physics was daunting!
When we started homeschooling, I never dreamed I would have a child that would take high school physics, let alone attempt it at home. My strengths are not in math & science. Thanks to Journey Homeschool Academy, advanced high school science classes have been a positive experience for us! I have confidence my son will be graduating from high school with a quality, rigorous science foundation and will be well prepared for post-secondary education.
With 8 kids to homeschool, I needed to delegate some of the teaching to someone else…
Discover Physics is not only quality educational content presented clearly and enthusiastically by excellent teachers, it has an independent learning format for students. This was such a good choice for our family!
If I just had a textbook, I wouldn’t be able to understand Physics…
However, the videos make the concepts easy to understand and follow. The visuals really help me grasp what being taught. And if I still don't get it, the ability to contact real teachers is life-changing!
I see so many people put their kids back in school when they get to high school, because they lack the confidence to teach high school science…
…thanks to you guys, that is no longer an excuse. The videos in this course are top notch and I like the layout of the workbook with the opportunity it provides to learn notetaking skills. This is a challenging course, designed well, and taught from a biblical worldview. Thank you for working so hard to put these amazing courses together!
I had taken Experience Chemistry and Discover Physics was the next one on my list...…
What I like most about the course is how Luke and Trisha explain the topics in new ways from one another as it helps me better understand the concepts. I’ve also appreciated the pre-made notes!
With physics, I was mostly concerned about labs and helping my student with homework…
I love that Discover Physics included all the teacher guides and helps so I could help out even when I didn’t know the exact answer myself. And I really appreciated that it was online and my student could work independently, so I could help my younger students who need more one-on-one time.
I so appreciate the perfect blend of faith and science in this course.
The Gilkersons have a logical, faith-based approach to creation. They don’t try to make it preachy like some Christian curricula, but maintain a high-standard for science academics. I love that my children have their faith and beliefs validated and enhanced while still getting high-quality academics.
You’ve got questions… we’ve got answers
What’s included in my purchase?
You’ll have access to all lesson and lab videos along with PDF downloads of the student guidebook, lab guide, curriculum guide, answer keys, homework help videos, and sample lab reports.
Should you want a physical copy of the guidebook or lab guide, those are available for purchase in our store. It is highly recommended that you purchase the textbook Conceptual Physics.
You will also be responsible for purchasing lab supplies for any labs you’d like your student to complete.
Are there any math prerequisites for this course?
Your student should have completed an algebra 1 course prior to taking this physics course. This is a rigorous math-based, physics course.
When should my student take this course? What grade?
We recommend students take this course in the 11th or 12 grade. Many parents choose to list this course as an honors course on their student’s high school transcript. There is a lot of math and the course moves at a fast pace to cover all of the material.
If you are looking for a class for younger students or students you’re not sure would be able to keep up with the pace of this course, we recommend checking out our Astronomy, Biology, or Earth Science courses. These courses are less advanced, but still appropriate for students seeking a science class for high school credit.
When does the course begin?
You’ll have immediate access to the course as soon as you register!
Since this course is self-paced, you, the parent, have control over when your student begins the course. You can start as soon as you register, or wait a few weeks or months. Beginning the course is as easy as pressing a button. Once you begin the course for your student, they will have one year to access the course.
How long will I have access to this course?
You’ll have access to the course for one year of access — you decide when your student begins the course. There are 35 weekly lessons, so that should provide ample time for your student to complete the course. Once each video is live, your student can watch and re-watch it anytime they would like to throughout the duration of the course.
Does my child have to view the course videos on specific days or times?
No, students can watch the lessons any time throughout the week. Once released, each video can be reviewed as many times as the student wants through the end of the course.
Can my student earn high school credit for this course?
In most states, students need to accumulate at least 120 hours of instruction and course work to receive a high school credit.
Many parents choose to record Discover Physics as an honors level lab-science on their student’s high school transcript. We recommend your student complete all of the following to accumulate the necessary course hours for high school credit:
- complete all the course lectures
- take all the quizzes and exams
- complete recommended readings
- watch laboratory videos and complete a minimum of 15 lab assignments
How you use this course and the resources available is ultimately up to you, the parent, as this is a homeschool course.
Can I enroll more than one student in this course at the same time?
In the upper level course, each student receives their own grade, online portal, and auto-graded quiz so each student should enroll separately. We do offer generous multi-student discounts for families enrolling more than one student in the class at the same time.
Can we use a different textbook for this course?
We believe parents are best equipped to determine their students’ educational needs. As a homeschool course, you’re welcome to choose whatever textbook you’d prefer for your student to use or omit textbook reading altogether if you’d prefer. For most students, anytime they can use multiple modes of learning it helps them retain information better.
After reviewing many, many textbooks we chose Conceptual Physics: The High School Physics Program because we believe this textbook does an excellent job of reinforcing the concepts students are learning in the lectures. We provide recommended reading for your student from this book. If you choose to use another textbook, you’ll need to be sure to assign students what you’d like them to read each week.
We have also created alternative reading schedules to accompany several other commonly used textbooks by homeschoolers. While we cannot vouch for every detail in these textbooks, the reading lists provided here generally overlap with what is covered in each of the lessons in the course.
In addition to our recommended textbook, Conceptual Physics, we currently have a reading list available for the following textbooks:
• Introductory Physics, Novare (2nd edition)
• Exploring Creation with Physics, Apologia (2nd edition)
• Physics, Bob Jones (3rd edition)
• Physics: The Foundational Science, Abeka (2nd edition)
How long do students have to complete individual lessons?
We recommend students plan to complete one lesson per week to finish the course during a typical school year. Once your student begins the course they will receive access to the next lesson within 1-2 hours of completing the current lesson. This allows you the flexibility to work ahead if needed to account for vacations or time off while still finishing the course in the typical timeframe. Students will have a full calendar year to complete the course, so if they fall a week or two behind, they should still have plenty of time to complete the course.
Can I take this course if I live outside the U.S.?
You sure can! We’ve made sure to make the lessons applicable to those worldwide.
What additional books or supplies will I need for this course?
Students will need a number of different supplies to complete the labs and activities work. See the complete Discover Physics Lab Supply List.
It is highly recommended, though not required, that you purchase the textbook Conceptual Physics: The High School Physics Program. While this is our preferred textbook for the class, we’ve also included reading lists for several other textbooks, or you may omit textbook reading.
A PDF download of the Student Guidebook and Lab Guide are available as part of the course purchase.
Can I pay for this course with my Educational Savings Account (ESA)?
We are an approved vendor with several ESAs and are continuing to add to the list all the time! We’re happy to provide you with invoices or other information you need to submit to your ESA. You can see all the ESAs we’re currently approved vendors with and/or submit a request for us to apply to the ESA in your state.
Do you offer options for using this course with a co-op?
We offer co-op pricing for groups of 4 or more who have designated a single instructor/ facilitator. Co-op courses are designed for groups that are meeting at least weekly.
Our co-op courses are set up differently than our family programs to accommodate groups. You can learn more about our co-op courses here.
