Concepts are experienced before they are named. Length, for example, is introduced operationally through the procedures needed to measure it. New words are introduced only as needed in order to effectively communicate on a subject. As a rule, only frequently used terms are introduced at all. Keeping to this discipline cuts down on new vocabulary words and guarantees that new words will become familiar through frequent use.
Investigations progress from the more familiar to the less familiar.
Investigations with the magnifying glass precede investigations with the microscope. Quantitative measurements are routinely made and mathematics is appropriately used as required. The investigations with the magnifying lens require measuring lengths and determining the ratio of one length to another.
