RSO Earth & Space Level 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 Level 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!
