Activity 2: The Incredible Shrinking Cube

① This example dynamically demonstrates a cube shrinking and subdividing into smaller cubes, visualizing the recursive changes in area and volume. ② Core math concepts include cubes, geometric sequences, logarithmic functions, scaling of area and volume, and recursive division. ③ Construction highlights: using GeoGebra's Segment command to build edges and vertices (A to H and primed counterparts), with multiple segment objects (f, g, h, i, j, k, l, m, n, p, q, r, etc.) forming a 3D framework, and sliders or animations to control the scaling factor and observe the shrinking sequence. ④ Suitable for upper secondary or pre-university students, useful for exploring the connection between geometric scaling, sequences, and logarithmic functions, and as an interactive resource for math modeling or dynamic geometry lessons.
