Presentation of New Knowledge (15 minutes)Types of Celestial Bodies•Stars: illuminated star-shaped objects seen in the night sky•Moon: Earth’s satellite•Sun: the central celestial body in our solar system•Planets: celestial bodies that orbit the Sun, including Mercury, Venus, Earth, Mars, Jupiter, Saturn,Uranus, Neptune, and Pluto.Observation Methods for Celestial Bodies•Direct observation: observe the moon, stars, and sun directly•Use of magnifying glasses: observe smaller celestial objects such as the moon and Mars•Use of telescopes: observe distant celestial objects such as stars and nebulaeHands-On Practice (25 minutes)The teacher will guide students in using magnifying glasses and telescopes to observe the closest celestial body, such as the moon or a star. Through demonstration and guidance, the teacher will teach students how to use a telescope.Expansion Activities (10 minutes)The teacher will show pictures and provide information about other planets, allowing students to learn about unique characteristics and names. Through discussion, the teacher aims to promote curiosity and imagination among students. Summary (5 minutes)The teacher and students will work together to summarize the knowledge and skills they have learned, and reinforce their understanding.Teaching EvaluationThe teacher will evaluate students’ performance during hands-on practice, using the following categories: excellent, good, passing, and poor. Additionally, the teacher may design related exercises to test each student’s learning outcomes. HomeworkStudents will be asked to observe stars and the moon at night and use language to describe their observations. Students will also be required to note the date and appearance of the last lunar phase on their calendars.
