Uncommon Supplies Needed for Course Labs:

Microscope– Choose either monocular or binocular, and either oil immersion or not. You don’t need to spend a fortune on a microscope, but avoid toy microscopes and those priced under $80 (new).
Microscope slides with covers
Dissecting pins
Dissecting tray or small pan
Forceps (for microscope specimens) or large tweezers
Lens wipes
Prepared slide of an allium (onion) root tip
Methylene blue dye
Oil for oil immersion slide (if applicable and if not included with microscope)
Prepared slide of a lilium (lily), anther meiosis
Legume inoculant (rhizobacteria)

Biology 2 in Action

What Our Customers are Saying

We are using Bio 2 with a mixed age group in a co-op setting. The format of the lessons are very easy to follow and the students find the labs fun and engaging. The content of each chapter is efficiently communicated and concepts are easy to understand with examples and illustrations to explain the more complex topics. Concepts and vocabulary are introduced and then applied in the labs. Materials for labs are easily-sourced items. The kids really look forward to lab day! Each chapter features a guided research portion that gives students a chance to learn about a famous science-related topic or scientist relevant to the chapter. There's a quiz at the end of each chapter that reinforces what they kids have learned (we use this to test their retention). I would highly recommend Bio 2 to individuals or co-ops looking for a well-rounded, hands-on approach to biology. I'm really glad we chose this curriculum for our students. The Teacher's Guide is indispensable.

We are loving Pandia Press Biology 2. My daughter loves the hands on, real world learning that takes her from her microscope to cooking in the kitchen to doing plot studies in local streams. I searched high and low for more than a basic - learn from a book, science course. This is hands on, real world experience and it's everything I was hoping for and more. She wants to be an aeronautical scientist when she grows up and Pandia Press is giving her a spectacular education that will help catapult her into whatever field she decides to go into.

RSO Biology is one of the few curriculum of any kind that has actually worked for our family. We love the layout. It's not overwhelming. You can just pick up and go and it's customizable. Several of my friends have been sold on the product after seeing my posts about our RSO labs on social media!

Reviews of Biology 2

REAL Science Odyssey Biology Level 2 Review

by Weird Unsocialized Homeschoolers

We used – and loved – REAL Science Odyssey from Pandia Press when my younger two kids were in elementary school. (You can read my reviews of Life and Earth and Space.) We loved the engaging lessons and hands-on labs. So, it makes sense that we would come back to the series for middle school. . . .

RSO Biology 2 Course Description


You will find R.E.A.L. Science Odyssey (RSO) to be unlike any other science curricula available. Most notably, it is secular: excludes any supernatural explanation for any event occurring in nature, including the origin of life. Only scientific inquiry and theory based on empirical and measurable evidence are understood to be valid and standard science in all of our RSO courses.

Also, RSO courses are written specifically for home and small group use. Packed full of serious science and loads of fun, RSO is an incremental program that gently builds on itself and incorporates mathematics, scientific method, and science terminology. Created with the science novice in mind, you don’t need any science background to teach RSO.

RSO Biology (Level 2) is a comprehensive course for life science at the middle school to high school level (grades 5 through 9). But unlike many science textbooks, RSO Biology 2 is not a dry collection of facts and worksheets but rather an in-depth course that engages young people’s minds at the same time they are actively participating in the learning of biology.

RSO Biology 2 has been created specifically for home and small group use. The course assumes no science background for teacher or student, and there’s no need for an expensive laboratory. Biology 2 uses natural settings that encourage students to explore the world around them. Most materials needed for labs and activities are commonly found items. A few items such as a microscope (microscope labs are optional but highly encouraged) and dissection specimens are easily obtained from science supply vendors.

New format: The course is now contained in three books (student textbook, student workbook, and teacher guide). The student textbook starts each chapter with an entertaining written lesson. The lesson is followed by several components in the student Workbook that are intended to reinforce the lesson, address the needs of different learning styles, and engage students in hands-on learning and research. These components include lab sheets, lab reports, problem sets, activities, famous science research assignments, coloring sheets, microscope labs, poetry, and vocabulary review. The parent/teacher’s text provides all the help a science novice needs to assist her student including suggested course scheduling, summaries, additional material and explanations, sample reports, learning objectives, answers and suggestions, tests, and quizzes. Divided into 32 chapters, Biology 2 provides a rigorous and complete biology course that covers a 36-week school year.
