RSO Earth & Space 1 Course Description


An add-on to Earth & Space is now available! Earth & Environment 1 Add-on is intended to be used as an add-on course to Earth & Space 1.  This add-on includes many of the labs and lessons found in Earth & Environment 1 that incorporate three new thematic elements not found in Earth & Space 1.

You will find R.E.A.L. Science Odyssey (RSO) to be unlike any other science curricula available. Most notably, it is secular. 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.

In RSO Earth & Space (level one), the topics include weather, seasons, the earth, minerals, rocks, our solar system, and space. Students study the weather and atmosphere with several hands-on labs including making an anemometer, a rain gage, and water cycle in a bowl. Rocks and minerals are studied in depth with students identifying their samples through the same tests used by geologists. Each planet in our solar system is studied individually as students make their own planet book. Earth & Space has recently been revised to include changes to the status of Pluto and the definition of planet.

The following is a list of topics your child will learn during the year while completing Earth & Space (level one). Each topic and/or subtopic will include 1 to 3 lessons complete with lesson story, labs, reading, and other activities. Each topic will take anywhere from 1 to 4 weeks to complete. Remember your child will also be having a whole lot of fun. Also included in this scope are laughing, playing, digging, exploring, reading, singing, and begging for more RSO!

RSO Earth & Space (Level 1) Scope and Sequence

The Earth

  • Weather and Seasons – monitoring weather, understanding seasons
  • The Water Cycle
  • The Earth’s Interior – crust, mantle, outer core and inner core
  • The Earth’s Surface – water and land
  • Minerals – what they are and how to identify them
  • Rocks and the Rock Cycle – igneous, sedimentary and metamorphic rocks
  • Erosion – wind, water, ice, and biological erosion
  • Soil

The Solar System

  • The Earth/Moon System
  • The Solar System – the sun, planets, and asteroid belts
  • The Planets – Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
  • Pluto is studied as a dwarf planet


  • Stars, Comets, Meteoroids and Asteroids
  • What’s Not in Space?


Uncommon Supplies Needed for Course Labs:

Science Thermometer– The liquid in good science thermometer goes down on its own, unlike the liquid in a medical thermometer, which must be shaken down. Some kitchen thermometers will work, but most do not go low enough. You will need a thermometer that will go down to 30° F or 0° C.

Inflatable Globe

RSO Rock and Mineral Kit & Streak Plate- A custom kit is available from Rainbow Resource. If you want to put together your own kit, you will need 1- to 2-inch samples of: Talc, Magnetite, Mica, Pyrite, Feldspar, Quartz Crystal, Granite, Basalt, Snowflake Obsidian, Conglomerate, Sandstone, Shale, Marble, Slate, and Schist. Plus, you need a streak plate to test mineral streak color. An unglazed kitchen tile (or even a sidewalk) can serve as a streak plate.

Triple beam balance (optional)

Binoculars– I would avoid the $10 ones, but you don’t have to spend $100.

What Our Customers are Saying

The thing I love best about Pandia’s science books is that they don’t make me feel overwhelmed from the moment I open them up, like so many other curricula. Instead of being faced with wall to wall text, written just to the teacher...I am faced with pages of small sections of text, broken up in a bite-size, easy to understand way, with the student pages and their cute illustrations mixed in with the units to add to the visual appeal. Each section is labeled appropriately so I can tell at a glance what I am looking at and I know what I am to do with each section: Peruse the list of materials for that unit, read a section designated as “read aloud” to my child, learn the procedures that we are going to be doing for a lab (and background info), find the printables for my child that go with that’s all there, in clear, manageable sections that make me feel like I CAN DO THIS. Plus, it’s fun, interesting, and hands-on, with lots of cool labs using mostly things from around the house!! We love Pandia science!

Review of Earth & Space

by Creekside Learning

If you’ve been here before, you may know that I love using hands-on curriculum with my kids. No surprise then, that we really enjoyed using R.E.A.L. Science Odyssey’s: Life (RSO) program. And this year, we will be using their Earth and Space curriculum and we are really looking forward to it...
