Read about scientific concepts and theories at the beginning of each lesson.
Each topic in RSO Level One is presented in an entertaining story-like format, followed by hands-on activities, background science information, parent instructions, labs, reading lists, journaling ideas, and websites.

Flexible and OrganizedOur comprehensive courses offer clear, easy-to-follow lesson plans that can be used as written or easily adapted your family’s particular needs and interests. Each course in the RSO series was developed to work with all ages, either independently at home or for use within a group. (Licensing is required for group, co-op, or classroom use.)
Academic and Hands-onGive your child an academically rigorous science education with our secular courses written by real scientists. Tap into your child’s natural curiosity through engaging text and creative hands-on labs and activities, while encouraging critical thinking skills and independent study.
From dissecting seeds, to comparing mollusks, to finding out how long it takes a message to get from your eyes to your brain and then to your hands, students will learn REAL life science in a way that is immersive and fun.
Exploring the properties of waves using a simple rubber band instrument, building a model of the Voyager space probe using household materials, and spending time gazing at the stars and journaling what you see are just a few of the creative activities within the course.
Making a timeline that puts Earth’s age into perspective, modeling the formation of igneous rocks, and creating a water cycle in a bowl in order to observe evaporation, condensation, and precipitation are a few of the creative activities included in the course.
From using the senses of sight, smell, and touch to explore the physical properties of matter, to creating a pH test solution using red cabbage, to learning about buoyancy by floating an egg in saltwater, students experience the concepts of chemistry in a way that is both immersive and fun.
Building simple levers and describing how they work, using different sizes and shapes of balloons to learn about rocket science, and learning what happens when you drink through a straw are just a few of the creative science experiments found within the course.
The RSO Level Two courses for middle and high school students bring science to life through engaging content, colorful images and diagrams, hands-on labs, research projects, and more.
Each lesson within the course books builds on the last and is designed to challenge students to conduct independent research, use critical thinking skills, and make connections between the concepts on the page and the real world. They are written at the student’s level to encourage independent learning, though Teacher Guides are available and highly recommended. Level Two courses include: Biology and Astronomy + The Stargazer’s Notebook.
The complete year-long Biology Level 2 curriculum requires this textbook as well as the accompanying Biology Level 2 Workbook. The Biology Level 2 Teacher Guide is also highly recommended.

We recommend the eBook version of the Teacher Guide as it contains helpful microscope slide answer keys and direct Internet links.
This course can generally be completed in 12 to 16 weeks, though some lab work, such as monitoring the sun and moon over an extended period of time, is continued after the completion of the main course. An Astronomy Level 2 Teacher Guide with suggested course schedules, sample reports, learning objectives, and test answers is available and recommended.
Additionally, to continue your study of astronomy for a full year, you can also purchase The Stargazer’s Notebook, which guides you in exploring the night sky with observation instructions, sky maps, labs, and more.

The smiles this curriculum produces are priceless! THANK YOU for creating such an amazing SECULAR curriculum!! –, homeschooling parent
We are on week 2 of Biology 2 and my kiddo can not get enough!
RSO Chemistry 1 is a fantastic, rigorous, secular science curriculum! It uses a multi-sensory approach to teach key principles and stays well clear of classic text-book style teaching. My kids are thoroughly enjoying this level and we highly recommend it!
After a ton of science curricula research, I finally ordered RSO Life Science! I am not a science person but I want my kiddo to love science. This seems like it’ll work for us both!
Every single year of homeschooling so far, (4 years), we have chosen a Real Science Odyssey program from Pandia Press. The lessons are informative, engaging, and fun! We have done Chemistry, Astronomy, and Physics, now Biology 2!
It's incredible after homeschooling for 18 years to find a resource that creates exactly what we were looking for in merging constant experimentation with text. Thank you once more for putting it all together.
Today in Biology 2, We talked about DNA and RNA and how fascinating it all is. Sooo fun! Thanks for a great curriculum Pandia Press!
I have tried various science resources over the years and have never found one I like as much as REAL Science Odyssey. Kudos!
