What does Fair Test Lab teach?

Fair Test Lab is a science game for 2nd grade – 5th grade that practises fair tests: change one variable, compare, conclude. Like every TernQuest game it is tied to a skill on the curriculum map (state standards — Common Core, NGSS, CSTA and History–Social Science, PK–5), and Pip the tern gives hints, never answers.

Is it free?

It is part of the Family Pass. A free account includes 50+ arcade games and every narrated story for one child; the Family Pass unlocks everything for up to 4 children.
