A note about BrainPOP was added to the printable schedule:
I’ve scheduled in some BrainPOP videos. Some high schoolers may find BrainPOP too childish. However, the videos are short and quite informational with short quizzes for each one. My kids still thought the BrainPOP videos were fun, even when they were older. You may want to look for a trial before spending the money on a subscription. If you decide BrainPOP is not a fit for your family, feel free to skip it.


All links were checked and broken links were fixed. Schedule formatting was changed. Videos were added in. Textbook links were updated to reflect our updated website. Workbook links were removed (as the workbook is now a single download found here:

4 thoughts on “Guest Hollow’s High School Biology Curriculum Online Schedule

  1. I couldn’t find where the video “Evolution vs. God” was scheduled. I looked through the online & printable schedule I purchased & didn’t see it in either one. Can you tell me what week we’re supposed to watch it?

    1. I should have marked that video as unscheduled. You can watch it whenever you wish! I’m updating the schedule to put that note in there! 🙂

  2. Can this curriculum be used for younger grades? I have a 5th grader and a 9th grader that I am searching for science curriculum for. My 5th grader is a little above her grade level, and my 9th grader is autistic and below grade level.

    1. Every student is different, so it’s hard to say what will work for kids I don’t work with on a regular basis in person. 😉 You know your kiddos best. I recommend you look over the book list, the online textbook, and the lab/supply list and see if you think it could be a fit. The curriculum was designed for high school, but like anything else we make, you can adapt it. I just don’t know if it would work in your situation or not. Sorry, I’m not too helpful! Another option may be to look at our anatomy program (Jr. Anatomy). That may be more of a fit. You may also want to post your question on one of our Facebook groups:
      Maybe other parents in the groups can help share what they’ve done. 🙂
