How each one plays by grade
R.E.A.L. Science Odyssey runs 5 grades further than Mystery Science. If you want one program to carry the subject for the long haul, plan on leaving Mystery Science around grade 5 and choosing again.
Mystery Science
Grades K-5
Works as a full curriculum through grade 2. Grade 3 is the turning point where you'll want more than an hour a week. By grades 4-5 most families run it as a supplement, and it ages out by middle school.
R.E.A.L. Science Odyssey
Grades K-10
Level 1 is parent-led with scripted readings and a lab most lessons, fitting the grammar stage. Level 2 is written to the student, adds formal lab reports, and Biology 2 includes microscope work and a couple of dissections.

Who Mystery Science fits
Secular K-3 families who want engaging science without much prep, especially a parent who'd rather not be the science expert and households juggling several young kids. Families who want a self-teaching program or rigorous depth past grade 4 should look elsewhere, and strict young-earth families won't want the evolution and old-earth content.

Fits secular and classical families who want a rigorous, hands-on deep dive into one subject at a time, with scripted lessons that carry a science-shy parent, for kids comfortable with evolution and an old Earth. Young-earth families wanting faith-integrated science, anyone wanting a zero-prep kit, and those needing dedicated grades 11-12 lab courses should look elsewhere.
