• Divide the class into groups of up to 5 students.

• Provide each group with a kit containing a flashlight, a marble, and the foam hemisphere.

• Explain that the flashlight represents the Sun, and the marble represents the Moon, which will move around the foam hemisphere that symbolizes the Earth.

• Ask students to recreate the four phases of the Moon by maneuvering the marble around the hemisphere and observing the changes in the Moon’s illumination.

• Each group should illustrate their observations by drawing and describing each Moon phase and the relative positions of the Sun, Earth, and Moon.

• At the end, groups will present their findings to the class, explaining their observations and how the Moon's phases are formed.

Activity 2 - Lunar Calendar Builders

> Duration: (60 - 70 minutes)

- Objective: Enhance planning and visualization skills while reinforcing knowledge about the periodicity of the Moon's phases.

- Description: In this activity, students will design and create a lunar calendar for a month. With poster board, markers, a ruler, and a paper model of the Moon, the groups will construct a calendar that visually represents each phase of the Moon, marking the dates and approximate times of each phase.

- Instructions:

• Organize students into groups of up to 5 members.

• Provide each group with poster board, markers, a ruler, and a paper Moon model.

• Explain that they need to create a lunar calendar for one month, visually depicting all Moon phases.

• Students must calculate and include the approximate dates and times of each lunar phase on the calendar.

• Each group will share their calendar with the class, explaining how they computed the dates and what each Moon phase signifies.

• Facilitate a concluding discussion about the significance of understanding the Moon's phases for cultural and daily planning.

Activity 3 - Lunar Phase Theater
