What makes a homeschool science curriculum secular?
It teaches science without religious content. Each listing on this page carries a worldview label from the maker's own description; read that description too, since science is the subject where programs differ most.
Is a science kit enough, or do we need a full curriculum?
Kits and subscription boxes add hands-on projects. A full curriculum adds a sequence, reading and review. Many families pair one of each. The listings below say which type each one is.

REAL Science Odyssey from Pandia Press
Secular
A secular science series with labs and activities. It comes in Level 1 and Level 2. For families who want science that builds year to year without a faith lens. Price: Level 1 courses from $43.99 (Astronomy, Earth and Environment) to $52.99 (Life, Chemistry, Physics, Biology). Worth it because each course covers one science for a full year, so the shelf holds one book instead of five.
An all-subject, literature-based year that includes science, history, language arts and math. For families who would rather buy science as part of a planned year. Price: All-Subject Packages $309.43 to $1,060.29 on bookshark.com right now (list $386.79 to $1,325.36). Worth it because science, reading and history arrive planned on the same schedule.
Live online science classes in small groups, taught by independent teachers. For kids who want a teacher, a lab demo and classmates. Price: set by each teacher, per class. $20 off a first class with code NEWTERM20 (one per household, end date not posted). Worth it because messy experiments become someone else's kitchen.
