This inquiry-based, modular science curriculum covers three strands: life science, physical science, and earth science. The pre-kindergarten/kindergarten level contains five modules, and levels 1-5 contain three modules each. The Teacher lesson manuals for levels 1-5 are accompanied by Teacher masters books for each module. The set is accompanied by three mini-modules for physical science (2 modules for levels 1-3 and 1 module for levels 3-5) which consist of Teacher lesson manuals and Teacher masters visual packs.
