Guest Hollow’s Biology Curriculum
brings science to life.
We’ve researched labs and activities from a variety of sources for a variety of budgets, created a comprehensive year-long daily/weekly schedule, put together workbook pages to help students better learn and retain the textbook material, researched and added in some terrific links, videos and other resources and added a list of supplementary reading to expand on the textbook concepts via “living books“.
There aren’t many options for a solid *Christian high school biology curriculum that is low cost and has lots of options, extras and engaging material to help expand concepts. That’s why we created Guest Hollow’s High School Biology by editing the well-known and esteemed CK-12 Biology Curriculum (thanks to a Creative Commons license CC BY-NC 4.0)!
We love science and want to give homeschooling families more options that are a bit different from the “norm”. Students and families love our curriculums! Try us, and you’ll see why!
*Secular families can use our schedule with the original CK-12 biology book. Click here for more info.
Question: What edits were made to the CK-12 text and materials?
We’ve taken the rigorous CK-12 biology textbook and edited it (thanks to a Creative Commons license) to fit a Christian creationist perspective. Edits are as follows:
- References to evolution were taken out.
- New videos were added. Students can watch them right from the online text!
- Christian material was added.
- Definitions were placed with vocabulary words in the beginning of each chapter.
- New pictures and illustrations were added.
- Custom illustrations were created to better communicate concepts.
- Additional concepts and material were added.
- Some humor was added and/or sections were rewritten to be more clear and understandable.
- Latin and Greek root word “alerts” were created and inserted in the text – a fun way to learn vocabulary using science!
- The human anatomy portion was taken out. We don’t believe several weeks study is adequate for a rich understanding of the human body. Check out our high school anatomy curriculum that fills this need.
- We edited the workbook to make it more visual with added humor and edits that reflect the changes in the Guest Hollow version of the textbook.
We also added a schedule that ties in a variety of lab options, activities, videos, workbook assignments, games, free printables, additional books, and more to make a rich learning experience that goes beyond the text!

I cannot even tell you how much Biology curricula I looked at before I finally (thankfully) found this one! It saved our year! It went along with my daughter’s learning style so much better than a boring textbook-only approach, heavy on the math with expensive, impossible labs. This one made biology do-able. We enjoyed (as a family) so many videos. The online lab options were life-savers some weeks. The worst part is having to leave stuff out because there is no way you can do it all! So much to choose from!
I was so anxious and felt so unequipped to teach my son his high school level courses starting this year. I wasn’t sure what curriculum I was going to use for science until a friend talk to me about this curriculum. I was so pleased and blessed to be a recipient of such a wealth of resources in this Biology curriculum. Couple of moms and I started our own co-op using this curriculum and are having such a blast seeing the kids enjoy it so much and learn in such an interactive way. I love all the resources that were put together for this curriculum. We love the videos the additional books and the fact that the links are free. The outstanding quality of this curriculum is beyond what I expected. I always dreaded having to create weekly schedules and planning a full curriculum. This course is set up week by week with all the instructions very clear and easy to follow even if my kids wanted to donut on their own.
Love it love it love it!!! I’m very greatful that someone took the time to bless others so abundantly! May God continue to bless your efforts.. Thank you for this gift!
Here are two reviews of Guest Hollow Biology, the first one written by me, the second one by my teen daughter.
Parent Review: We used Apologia science books for a number of years and they worked well for us. When we got to Biology though my daughter began to struggle. The reading was difficult, the material hard to understand. She loves science, but I could see the joy of learning Biology fading fast. Enter Guest Hollow. It was recommended to me by other Homeschool Moms, and I couldn’t be happier with it.
First of all, the textbook is free, which made it easy to give it a try. The lessons are laid out in an easy-to-read format. Each lesson contains videos to help cement the concepts, which is especially good for students who are visual learners.
The curriculum comes complete with a weekly schedule that simplifies things for the Homeschool Parent. It really is Open and Go. There are optional labs within Guest Hollow Biology, plus supplementary reading suggestions, and printable worksheets (except for the last three chapters but I’m hopeful those will be added).
My daughter has done very well using this Biology curriculum. It’s mostly independent, and she has been able to understand and retain the material. I wasn’t sure about her using an online curriculum since we have never used one before, but she really likes that aspect of it.
Student Review: Guest Hollow is a very easy to use, very clean formatted biology. I really enjoy using it. I like how they explain things in an easy to understand form, not too over my head. I like the videos that are inserted throughout the text. It helps me grasp some concepts that I may not be getting just by reading the text. Some of them are interactive, which is neat cause it is almost like a lab.
So, to sum it all up: We love Guest Hollow Biology! I anticipate that we will follow this year up with Guest Hollow’s Chemistry. Thank you for a great curriculum!
Callie Conley –
I hated biology before I found Guest Hollow! I am a visual learner, and Guest Hollow Biology gives tons of videos to watch, reading interesting books, and hands-on activities like dissecting and experiments. Now I love biology thanks to Guest Hollow!
As a student, this was a very fun biology textbook. I liked how you incorporated videos into the book. I fell like I could talk to someone about biology more after doing this course. Thanks for everything!
Leah Sours –
I liked all of the videos however, I felt like there were too many workbook pages.
Heather Powell –
Last summer, I researched biology curriculum that would prepare my 9th grader for the biology SAT subject test the following Spring. In 5th grade, she enjoyed Big Otter’s anatomy course, so we looked at what Guesthollow had to offer for high school. The free CK-12 online textbook that Guesthollow uses lines up well with what is included on the subject test. The videos, labs, extra books, and worksheets included in this curriculum helped her retain what she read in the textbook. In addition to Guesthollow’s biology curriculum, she reviewed what she had learned with Barron’s SAT subject test preparation guide. This book filled in what she needed to know about evolution and human anatomy for the test. Last May, my daughter took the SAT biology E subject test and scored a 740. I am grateful to Guesthollow for all the work put into this free high school biology curriculum, and we plan on using their Chemistry curriculum for 10th grade.
As a student, I found this Biology curriculum very interesting and fun. I was behind a few years, but this definitely helped me catch up. The videos were really interactive, plus I loved how the Christian’s perspective were added to the topics. However, I think the workbook assignments were too much work! Even so, I enjoyed this Biology curriculum. Thank you!
We have completed Guest Hollow’s Biology, Chemistry and Physics curricula. Biology is by far my daughter’s favorite! She enjoyed the “real life” books that were much more engaging than a boring textbook. She commented that each lab was “fun in it’s own way,” and “they helped solidify the content for me.” A great way to earn high school credit without tears!!!
My daughter will be in 12th grade this fall. We started using Guest Hollow Biology when she was in 9th grade. Before that we had used Apologia textbooks for science which we thought were nice. When we switched to Guest Hollow we both thoroughly enjoyed her science studies and we learned and shared so much. The choice of books, videos, and games is an educational feast that was so pleasing to our minds! Thank you for prompting us to savor our science studies! My daughter is considering an occupational therapy career because of her enjoyment of science.
Nicole Echols –
So excited that we found Guest Hollow Biology this year! It’s been a fantastic fit for our family. The curriculum is engaging with just the right amount of videos, colorful illustrations and information. It keeps the attention of all three of my high schoolers. Thank you for making Biology come to life!
JENNIFER GUEST –
Thank you so much for the feedback! I’m so glad your highschoolers enjoyed the program! Thank you so much for posting. 🙂 It’s a big encouragement to me!
Kate Polakowski –
I found this Biology curriculum to be very engaging and useful. The sections on evolution made me research the evidence in greater depth and reminded me not to take everything I read for absolute fact. The different components such as videos and online activities helped my brain to focus and absorb information much better, and I enjoyed the writer’s funny quips throughout the text. This Biology course made me look forward to studying science! My only wish was that the curriculum had presented more fully the differing opinions in the argument about evolution and a two billion year old earth. Other than that I greatly enjoyed the course. Thanks for a lovely semester of biology!
JENNIFER GUEST –
Thank you so much for your review! I appreciate the feedback! <3 I’m so happy you enjoyed the course.
A Thankful High Schooler –
I loved this curriculum for it’s easy to understand nature, as well as your Christian worldview.
Thank you for your amazing work, my classmates and I loved it!
Jennifer Guest –
Thank you so much for leaving a comment! I’m so glad you and your classmates loved it. 🙂
Hope Smith –
I loved this biology curriculum. My sister and I did it together and loved it. Thank you for all the work you put into it.
Jennifer Guest –
Thank you so much for your comment! 😀 You totally made my day.
Mona Koerner –
We thoroughly enjoyed Guest Hollow Biology. The ability to choose activities was great. The literature suggestions were wonderful and my daughter found many things to read on her own as a result. I appreciated the online text with embedded videos we were able to read/watch as we went along much more interesting than a straight text book. We also enjoyed many, many good full length (hour long videos) we usually watched these for our lunch hour. Thank you GuestHollow! Biology became my daughter’s favorite subject this year.

I just wanted to leave a review for your Biology curriculum, which we just finished in June of this year. I was in 10th grade. I really enjoyed it. The lessons were easy to read, and they made sense! I have dyslexia, and it can be difficult to understand stuff, but your lessons made sense to me. They were funny at times, and I enjoyed the videos. (The ones I watched. 🙂 And I liked that fact that if I found a mistake, I could let you know, and you would fix it, and thank me. That was really nice. The work sheets were also super helpful, and made sense. The optional living books were also a super fun bonus! “For All the Tea in China” was so cool that I gave a report on it in our yearly end-of-school presentations. All in all, I really enjoyed your biology course, and I am super glad my mother made me do it. (And found it!)
Andrea Mulder (verified owner) –
We used this curriculum with my freshmen daughter. Overall I thought the curriculum thorough and informative. Most of the accompanying books were useful, interesting and educational. My daughter learned biology in an interactive and satisfactory way.
Two critiques: I thought the books on evolution were good and relevant to the curriculum. However, the Answers books , while great for general apologetics, are not specifically biology. It felt irrelevant and therefore excessive in an already overflowing curriculum. For reference, we are a Christian family.
Second, there were way too many workbook pages for each section and I found it very difficult figure out which pages I could have her skip without losing content. I also found many of the workbook page questions written in tricky ways to make it difficult to understand. I think these need editing.
Jennifer Guest –
Thank you so much for your feedback! We didn’t write the workbook questions, CK-12 did – but I think that’s something we may consider changing in the future (to be like our other curriculum workbooks). I also appreciate your feedback about the Answers books. We’ll consider finding some substitutes! Thanks so much for leaving your review and for the excellent critiques! <3
Bex Buzzie –
Jen And Charles are probably the most genuine people I have encountered. They put their heart into their products because they have you in mind. They understand the struggles and pitfalls of traditional curricula like in the upper level sciences with a no math approach! It has been such a blessing to know they exist to support the homeschool community!
Jennifer Guest –
Awwww, thank you so much for the kind words! <3 We both enjoyed our FIRST podcast with you!!
To anyone reading these comments, go check out Bex’s site: https://thehomeschoolpodcast.org/ Our interview will go live in the middle of June 2022. 😀 Bex is such a sweet woman who really loves the homeschooling community and is working hard to support it! We loved working with her (once I got over my introvert panic attack -exaggerated but barely, lololol).
Leah S (verified owner) –
My 14 year old daughter loves this curriculum so much that she asked to continue Guest Hollow for her a science the duration of High School. The schedule is easy to follow and she loves the books that go along with it.
