Lesson Plan | Active Learning | Main Phases of the Moon

Assumptions: This Active Lesson Plan assumes: a 100-minute class, prior student study with both the Book and the start of Project development, and that only one activity (among the three suggested) will be chosen to be conducted during the class, as each activity is designed to take up a significant portion of the available time.

Objectives

Duration: (5 - 10 minutes)

This stage of the lesson plan aims to establish the learning objectives that will guide the classroom activities. By clearly defining what is expected for the students to achieve, it facilitates the organization and focus of practical activities. The outlined objectives aim to ensure that students can not only recognize the phases of the Moon but also understand the mechanism behind their change and the regularity of their cycle.

Main Objectives:

1. Empower students to identify and describe the four main phases of the Moon (new, waxing, waning, full).

2. Develop understanding of the periodicity of the Moon's phases, highlighting that they repeat in a cycle of approximately 29 days.

Side Objectives:

1. Encourage observation and recording of natural phenomena as part of the scientific method.

Introduction

Duration: (20 - 25 minutes)

This stage of the lesson plan is designed to engage students and connect the prior knowledge acquired about the phases of the Moon with real-world situations. The problem-based situations serve to activate critical thinking and prepare students to apply their knowledge in new contexts, while the contextualization helps understand the relevance of the phases of the Moon in daily life and history. This initial process of questioning and contextualization aims to ensure that students are motivated and ready to explore the topic in depth during practical activities.

Problem-Based Situations

1. Imagine you are an astronaut on a special mission to study the phases of the Moon and you need to explain to the support team on Earth what you observed. How would you describe each phase of the Moon and what could you say about the periodicity based on your observation?

2. If you were at a campsite and needed to predict whether the next night would be ideal for observing the full Moon, what information about the phases of the Moon would be important? How would you use this information to make your prediction?

Contextualization

The phases of the Moon are a fascinating astronomical phenomenon and are present in many cultures around the world, even influencing rituals and traditions. For instance, ancient Egyptians used the phases of the Moon to help predict the flooding of the Nile River, which was essential for agriculture. Moreover, the Moon plays a crucial role in the formation of tides, demonstrating how events in space have direct impacts on Earth.

Development

Duration: (70 - 75 minutes)

The Development phase is designed to allow students to apply and deepen their prior knowledge about the phases of the Moon in a practical and interactive manner. Through playful and creative activities, students will be able to visualize and manipulate complex astronomical concepts, facilitating comprehension and retention of the content. This approach also promotes teamwork and creative expression, which are important skills for the holistic development of students.

Activity Suggestions

It is recommended to carry out only one of the suggested activities

Activity 1 - Moon Phase Hunters

> Duration: (60 - 70 minutes)

- Objective: Visualize and understand the phases of the Moon through practical observations and simulations, reinforcing theoretical learning about the topic.

- Description: Students will be organized into groups of up to 5 members and will receive a 'mission letter' that describes a series of observations to be carried out during different phases of the Moon. Each group will receive a kit containing a flashlight, a marble, and a Styrofoam hemisphere to simulate Earth. They will use these materials to recreate the phases of the Moon, observing how the position of the light (flashlight) and the position of Earth influence the appearance of the Moon.

- Instructions:

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

• Distribute a kit to each group, containing the flashlight, the marble, and the Styrofoam hemisphere.

• Explain that the flashlight represents the Sun and the marble represents the Moon, which will be moved around the Styrofoam hemisphere representing Earth.

• Ask the students to use the materials to recreate the four phases of the Moon, moving the marble around the hemisphere and observing changes in the illumination of the 'Moon'.

• Each group should record their observations, drawing and describing each phase of the Moon and the relative positioning of the Sun, Earth, and Moon.

• At the end, each group will present their findings to the class, explaining what they observed and how the phases of the Moon are formed.

Activity 2 - Lunar Calendar Builders

> Duration: (60 - 70 minutes)

- Objective: Develop planning and visualization skills, as well as reinforce knowledge about the periodicity of the Moon's phases.

- Description: In this activity, students will design and build a lunar calendar for a complete month. Using cardstock, markers, a ruler, and a paper model of the Moon, the groups will create a calendar that visually represents each phase of the Moon, highlighting the dates and approximate times of each phase.

- Instructions:

• Organize students into groups of up to 5 people.

• Provide each group with cardstock, markers, a ruler, and a paper model of the Moon.

• Explain that they must create a lunar calendar for one month, visually representing all the phases of the Moon.

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

• Each group will present their calendar to the class, explaining how they calculated the dates and what each phase of the Moon represents.

• Encourage a final discussion about the importance of understanding the phases of the Moon for everyday and cultural planning.

Activity 3 - Moon Phase Theater

> Duration: (60 - 70 minutes)

- Objective: Foster creativity and understanding of the phases of the Moon through artistic and playful expression.

- Description: Students will create a small play that simulates the phases of the Moon. Each group will be responsible for representing a different phase, using materials such as fabrics, cardstock, paints, and makeup to create a set that illustrates the phase of the Moon, as well as the movements of the Earth and Moon that cause it.

- Instructions:

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

• Distribute materials such as fabrics, cardstock, paints, and makeup.

• Assign each group a phase of the Moon to represent.

• Students should create a set that represents the phase of the Moon and the movements of the Earth and Moon that cause it.

• Each group will present their scene to the class, explaining what they are representing and how the phases of the Moon are formed.

• At the end, there will be a discussion about the presentations, highlighting the creativity and understanding of the phases of the Moon demonstrated.

Feedback

Duration: (15 - 20 minutes)

The purpose of this section is to consolidate learning, allowing students to articulate what they have learned and hear the perspectives of their peers. The group discussion helps reinforce the concepts of the phases of the Moon discussed during practical activities, as well as promote communication and argumentation skills. This phase also serves to identify any gaps in understanding that may still exist, allowing the teacher to clarify doubts and reinforce key points of the content.

Group Discussion

To start the group discussion, the teacher can say: 'Now that everyone has had the opportunity to explore the different activities, let's share what we learned. Each group will have a few minutes to present the most interesting findings and challenges encountered during the simulations and constructions. Remember to explain how the phases of the Moon are formed and what each phase represents.'

Key Questions

1. What were the biggest difficulties encountered while trying to recreate the phases of the Moon, and how did you overcome them?

2. How did the simulations help to better understand the periodicity and characteristics of the phases of the Moon?

3. Is there a way in which what you learned about the phases of the Moon can be applied in real situations or in other areas of knowledge?

Conclusion
