Description
Updated for the most recent AP Biology Course and Exam Description! This resource is designed to help guide your AP Biology students to learn, study, and review all of the topics in Unit 3. No prep, print and go!
Each Essential Standard is written out on the left side of the paper, with focused, open ended questions on the right side for students to work through.
Topics for AP Biology Unit 3:
- 3.1 Enzymes
- 3.2 Environmental Impacts on Enzyme Function
- 3.3 Cellular Energy
- 3.4 Photosynthesis
- 3.5 Cellular Respiration
The entire resource is editable. Worksheet questions are packed tightly to conserve paper! Or complete digitally!
Includes a comprehensive answer KEY!
Updated for the Most Recent CED
The College Board made a handful of changes to each Unit which I have highlighted in the editable Key so you can quickly find them. Check out this blog post, “What is Different about the new AP Biology 2025 CED?” It goes over all of the changes in detail!
Save hours of time!
**Bonus** Save hours of time searching for resources to teach with! Purchase includes a curated list of resources. Arranged and organized for each unit topic. These are resources I use myself, so if you have questions about any of them, just ask! The list includes online interactive activities, video clips, and Lab ideas and classroom activities for your students. Since the internet is constantly changing, some links go dead every year. I spend part of my summer weeding through the links, deleting and replacing any dead ones as I can. I then send out an update for everyone to have the new links.
My AP Biology students benefit tremendously from having quick access to the Essential Knowledge standards and these guiding questions. After going through each set, they feel confident they are ready for the Test!
How to use this resource:
- While going through a Unit as a working document, students can add to it as they learn
- Just before a Unit test as a study guide
- At the end of the semester to prepare for the AP Biology Exam
It is helpful to have students begin by going through the Essential Knowledge itself, highlighting key vocabulary. This gives them a good foundation to grow from, they know what to look for and what is important as they learn about, or review for the Unit.
When my students use these as review, I put them into small groups of three or four. They work together to complete the questions. Then students get into new groups and review their answers. I help guide them and help with questions that they can not come to an agreement on.
