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.

Science K covers the body, senses, plants, and weather; Level 1 does trees, habitats, and insects; Level 2 leans physical science; Level 3 adds earth and space; Levels 4-5 move into cells, ecosystems, energy, and geology. The whole line runs K-5.

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.
