理科ラボ: A Small Interactive Middle-School Lab

Field notes

理科ラボ presents each lesson as a question followed by a controlled comparison: students alter one condition and inspect the resulting diagram, measurement, or motion. Its 35 materials are indexed by middle-school year, science field, and unit, with examples ranging from P/S-wave timing and circuit layouts to Moon position and energy bar graphs. The site says the collection does not yet cover every unit and that additional experiments and observations are being added progressively.
