What this lesson teaches

Earth spins once each day and orbits the sun each year, which creates repeating patterns: shadows shift through the day, day turns to night, and different stars appear in different seasons.

Worked examples

Example 1

A stick in the ground casts a long shadow in the morning, a short one at noon, and a long one again in the evening. The shadow moves in the same pattern every single day as Earth spins.

Example 2

The sun rises a little farther north each day from winter to summer, then heads back. The pattern repeats every year.

Example 3

We see the sun 'move' because Earth spins, not because the sun travels around us. The pattern is real; the explanation took centuries to get right.

Practice questions

  1. Measure a shadow's length three times in one day and record the times.
  2. Graph how the shadow changed from morning to evening.
  3. Use your data to explain what causes the daily pattern of day and night.

Patrones en el Cielo

La Tierra gira una vez cada día y orbita el sol cada año, lo que crea patrones que se repiten: las sombras se mueven durante el día, el día se convierte en noche, y en distintas estaciones aparecen distintas estrellas.

Ejemplo 1: Un palo clavado en la tierra proyecta una sombra larga en la mañana, una corta al mediodía, y una larga otra vez en la tarde. La sombra se mueve con el mismo patrón todos los días mientras la Tierra gira.

Ejemplo 2: El sol sale un poco más al norte cada día del invierno al verano, y luego regresa. El patrón se repite cada año.

Ejemplo 3: Vemos que el sol se 'mueve' porque la Tierra gira, no porque el sol viaje alrededor de nosotros. El patrón es real; la explicación tardó siglos en aclararse.
