Quando Usar Solar Eclipse 3D Explorer - Melhores Sessoes
freetoolonline.com editorial teamO Solar Eclipse 3D Explorer é ideal para demonstrações em sala de aula e aprendizado sobre eclipses solares com os cones de umbra e penumbra da Lua varrendo a Terra - não é um efeméride ou calendário de fases.
| Parâmetro | Valor |
|---|---|
| Largura da umbra | 100 - 270 km |
| Tamanho angular do Sol | ~0,53 graus |
| Tamanho angular da Lua | ~0,52 graus |
| Tempo de varredura (1x) | ~12 segundos |
A demonstracao de cinco minutos em sala
A demonstracao de cinco minutos em sala is the ideal session: open Solar Eclipse 3D Explorer, press Play shadow, and let the class watch the Moon's umbra sweep Earth while the panel names each phase. Pause at 50 percent progress and read umbra width from 100 to 270 km - faster than a flat diagram alone.
Shadow cones and the totality path
Solar Eclipse 3D Explorer suits teaching shadow cones because the penumbra and umbra meshes show where the Moon's shadow falls on Earth. Students can scrub to totality, toggle the totality path, and connect the narrow central track to nearly equal Sun and Moon angular sizes - about 0.53 deg versus 0.52 deg.
Fullscreen shadow pacing
Solar Eclipse 3D Explorer in fullscreen keeps the play button, progress slider, totality path toggle, and facts panel visible while Sun, Earth, and Moon stay in view. Press Play shadow and one sweep across Earth compresses in about 12 seconds at 1x - enough motion to hold attention without sound or accounts.
Sessions it does not fit
These sessions do not fit Solar Eclipse 3D Explorer: any time you need the date of the next real eclipse, tonight's Moon phase, or Earth's shadow on the Moon at full moon. The scene does not run an ephemeris, does not match today's sky, and does not show lunar-eclipse geometry (Earth's shadow on the Moon - use Lunar Eclipse 3D Explorer). For everyday phase names and the 29.53-day synodic cycle, use Moon Phases 3D Explorer. It also needs WebGL in the browser.
