How to guide primary school students to observe the starry sky in four seasons by using active star map

1. Observe and explore the summer starry sky and typical constellations; You can communicate with students and introduce the constellations and methods they observe under the stars of the four seasons.

2. Choose the constellation of interest independently, participate in long-term scientific exploration activities, and explore the starry sky in the four seasons; Willing to cooperate and communicate in activities.

3. Know the changing rules of the Big Dipper and other constellations throughout the year; Understand the four seasons starry sky and its constellations.

Scalable goals:

Continue to observe the starry sky and discover more secrets about it.

Teaching preparation:

1, to guide and encourage students to observe the stars and constellations in summer; And collect and sort out their typical constellations and related materials in the starry sky of the four seasons.

2. Prepare some information about the starry sky in summer, such as pictures or videos of the Milky Way and the summer triangle.

Teaching process:

Dialogue introduction: With the arrival of summer, the beautiful starry sky is more brilliant. We can not only observe the majestic Milky Way, but also see the scene where the Cowherd and the Weaver Girl meet in the Summer Triangle. (If you have prepared video materials about the starry sky, you can play the video first, so that students can feel the beauty and magic of the starry sky and have a strong desire to explore. )

Activity 1:

1. Let students discuss their observations and findings collectively before class. For example, students can show the changes of the handle of the Big Dipper in spring and summer.

2. Guide the students to communicate what changes have taken place in the constellations they have observed and explored and the starry sky in summer, so that students can fully tell their observation methods, observation time, observation place, observation feelings and collected legends about constellations, which can be pictures, written materials and observation records.

Teachers should create a relaxed and free environment for each participant so that they can fully express their views.

4. Show the information card in the textbook and two front and side pictures of the Milky Way, or show the pictures and written materials about the Milky Way collected by yourself and students.

5. Finally, through the full map of the starry sky and related materials and courseware, let the students fully communicate the changes of their observed constellations from spring to summer and the typical constellations of the starry sky in summer. On this basis, we can also exchange knowledge about the summer starry sky and constellations, as well as the beautiful legends about the cowherd and the weaver girl and the legends of other constellations, so that students can have a comprehensive understanding of the summer starry sky and constellations.

Activity 2:

1. Students communicate in the group and sort out the first-hand information they have observed, recorded and collected on the starry sky and related constellations in the past year, including observation methods, their own feelings and discoveries.

(1) Ask the students to show and exchange their observations on the Big Dipper in one year, and draw four pictures of the Big Dipper in autumn, winter, spring and summer.

(2) Cassiopeia and Pegasus in autumn, Orion and Ursa major in winter.

(3) Cancer and Taurus in spring, Cygnus in summer, Summer Triangle, etc.

2. Guide the students to discuss and summarize the laws of starry sky changes according to observations, records and related materials, and arrange the records of the four seasons changes of the selected constellations in the sky in their favorite way, and leave space for students to arrange and display.

3. Have a big discussion and exchange in the form of the whole class, show the changing rules of the starry sky and constellations summarized by students, guide students to learn from the experience of others, and constantly improve their own discovery and understanding, so that the whole class can realize the changing rules of the starry sky and constellations throughout the year.

Free activities:

1. Organize students to speculate and guess what will happen to the starry sky, the observed constellations and other constellations they are interested in in in the new year cycle. Make reasonable judgments and guesses.

2. Guide students to put forward new research questions on the basis of original observation, and discuss the scientific nature of the questions in groups. Let the students in the group make a plan and discuss the feasibility of the plan.

3. Confirm that the regularity of summary is correct, and keep observing to see if there are more and more valuable discoveries.

Evaluation:

Let the students in the group evaluate themselves and other students from the aspects of "persistent long-term careful observation", "observation record" and "finding problems", and encourage them to continue to observe the stars and constellations for a long time and strive to make new discoveries.

Outreach activities:

Guide students to continue to observe the starry sky and the constellations they are interested in. Regularly carry out some exchange and exhibition activities, compare who can observe persistently, see who finds more and who finds valuable problems, so that everyone can strive to be "little astronomers" and let the activities be truly implemented.
