Welcome to Guest Hollow's High School Biology workbook page!

Biology curriculum

Click here to go back to Guest Hollow's Biology main page and access the other components of Guest Hollow's Christian High School Biology Curriculum.

Each download is a packet of workbook and activity pages to help your students better learn and retain the information in the textbook chapters. Don't feel like you have to use them all. They may be more helpful to some students than others.

Click to tip!

Some of the workbook activities are:

  • True/False questions
  • Multiple Choice
  • Vocabulary match-up
  • Fill in the blank (vocabulary)
  • Draw items
  • Critical reading - read a passage and then answer questions
  • Critical writing
  • Compare & contrast
  • Cut & paste activity (kind of like lapbooking on a notebook page)
  • Fill out the diagram
  • Etc.

Most, but not all, workbook pages are adapted from the original CK-12 workbook.

Changes made:

  • References to evolution taken out
  • Graphics & text added
  • Format made more student-friendly and visually appealing
  • Some assignments adapted, deleted or added
  • Humor and cartoons added
  • Some appropriate/related Bible verses & Christian material added

Image credits are included with each image. Anything not credited is either hand-drawn or photographed by me or from Microsoft clipart, Clipart.com or in the public domain.

If you would like to help support my efforts (workbook files are big and take up bandwidth when you download them!), please see my website support page for how you can contribute to guesthollow.com. Even a small amount helps.

The files below require you have a free program to open PDF files.


*NOTE: If you want to save ink, have your student write the answers to the questions in a notebook for pages with true/false and multiple choice questions. Only print out activity pages that require cutting & pasting, etc.

The rest of the workbook pages may be created at a later date. These pages are lower in my queue than other materials I am working on, since this biology curriculum is accessible for free online and was originally created for my son and not my business. I need to make earning an income via this website my priority at this time. Thanks for understanding! You can use the original CK-12 workbook pages and access the answers via the resources tab on this page: https://www.ck12.org/workbook/CK-12-Biology-Workbook/.
