Unit 4
Starts
We'll be reviewing Unit 4's concept on cell communication and review homeostasis. Long distance and short distance cell signaling will be covered, as well as positive and negative feedback loops. Please be ready to participate and engage!

Biology Crash Course
11th session
Get ahead of everyone else in your honors/on level biology class. This course reviews a little bit of 8th grade biology and covers the entirely of 9th grade biology, getting you ready for any future biology class that you are willing to take!

Biology Course 🌱🧬
13th session
Welcome! In this series, we will go over all the units in Khan Academy's High School Biology Course (NOT AP/IB). I will go over content in each session, and we will do Khan Academy practice problems. I intend on making sessions interactive and engaging. I hope to be able to help you learn about biology! :)🧪🔬
❗🕕 Sessions are planned to be on Saturdays at 6pm EST. There is no set end date yet. Sessions will be added as time goes on.
🐢Sessions are pretty slow-paced. The sessions are slow paced because I want to make sure each learner knows the content well. 💡
The units we will go over include:
1. Ecology and natural systems
2. From cells to organisms
3. The cell cycle and differentiation
4. Energy and matter in biological systems
5. Gene expression and regulation
6. Inheritance and variation of traits
7. Mechanisms of evolution
8. Common ancestry and phylogeny
There is unit 9 as well but I won't be going over that in my series.

Biology Olympiad Prep
18th session
⁹Are you preparing for the Biology Olympiad, or just want to dive deeper into biology? In this series, we’ll work through key topics covered in the USABO open exam, including cell biology, genetics, physiology, ecology, and more. Each session will focus on 1–2 chapters/concepts, with practice questions and discussion to strengthen understanding.
This series is great if you:
- Want structured preparation for the Biology Olympiad.
- Enjoy learning advanced biology topics beyond the classroom.
- Like reviewing with examples, problem-solving, and explanations.
We’ll go step by step through the material and build a strong foundation for competition success. No prior Olympiad experience required—just curiosity and dedication!
Note: This series will be lasting into January to cover as much material before the Open Exam.
