Here's a free high school biology curriculum for you! If your child is participating in our high school biology labs this fall, or if you're just looking for an inexpensive, but pretty awesome way to present biology at home, I've made a reading list for the free High School Biology Flexbook available on CK12.
CK12 provides free, interactive textbooks. Each chapter includes a lesson, videos, interactive adaptive review, and an in-lesson tutor. That means that the free High School Biology Flexbook is an all-in-one curriculum. Sign into the teacher's version for a teacher's guide!
The reading plan is for CK12 Biology for High School . It's a weekly schedule, so you'll still have to determine how much you want to do each day.

You can download the reading plan here in Excel.
If you're looking for more free resources (like a reading plan for World History Modern Era), I'm putting the links on one page! Stay tuned!
