Eclipse Seasons on a Yearly Timeline

Start with the lunar month diagram, then the tilted orbit sheet. Use the 2025 timeline to test the model, and add the pendulum sheet as evidence of rotation.

Place four 2025 eclipses on a timeline and match each to a full or new moon phase. The directions on the page read: Use the phase key to fill in the table of 2025 eclipses (dates from NASA). Write each eclipse's letter above its date on the timeline. An answer key is included.

Yes, both. We made it for 8th grade Earth and space, and it works the same at home or at school. At home, a student can work through it alone and then go over it with you, which shows quickly what is solid and what needs another look. In class it works as independent practice, homework or a warm-up, and you can print one copy or a full set.

An eclipse season is a stretch of a few weeks when the Moon's nodes line up with the Sun, so both solar and lunar eclipses can happen. In 2025, a lunar eclipse on March 14 was followed by a solar eclipse on March 29. The timeline sheet places all four 2025 eclipses.

A lunar eclipse happens when Earth's shadow falls on the Moon. That requires Earth to be between the Sun and the Moon, which is the full moon position. A solar eclipse needs a new moon instead.

The pendulum keeps swinging in the same direction, but the floor under it turns with Earth. At the North Pole the swing turns about 15 degrees per hour, and at the equator it does not turn. The pendulum sheet graphs the rate by latitude.
