What it practices
Sorting things into science categories, one grade at a time: living and nonliving, floating and sinking, and animals and plants in kindergarten; animal coverings, plant parts and light sources in 1st; solids, liquids, weather and life cycles in 2nd; magnets, planets and renewable resources in 3rd; conductors, producers and physical changes in 4th; mixtures, gases and food chain roles in 5th; elements, metals and rock types in 6th; cell parts, organs and chemical changes in 7th; and chemical and physical changes, Earth's layers, the solar system and electromagnetic waves in 8th. Brick Lab makes it a test of aim: every brick you break is a decision, and a wrong one explains why it does not belong.
