Lesson 16

春季星空

Starry sky in spring

1. 残雪消融，枝头绽绿，斗转星移。转眼间，大自然洋溢着春天的气息。

Snow melt, branches bloom green, stars change. In the twinkling of an eye, nature is full of the breath of spring.

 同学们，经过这一段时间的观察，北斗七星和冬季其他星座发生了怎样的变化呢？有没有新的星座闯入我们的视线？用自已喜欢的方式观察、记录。

Students, after this period of observation, what changes have taken place in the big dipper and other constellations in winter? Are there any new constellations in our sight? Observe and record in the way you like.

一天中的变化

Changes in the day

发生了哪些变化？

What has changed?

从冬到春，星空又从冬到春的变化

From winter to spring, the starry sky changes from winter to spring

根据从秋到冬、从冬到春对星空的观察，我们发现了什么？

What do we find from the observation of stars from autumn to winter and from winter to spring?

我对北斗七星变化的预测是正确的 。

My prediction of the change of the Big Dipper is correct.

星空的变化可能有 这样的规律。。。。。。。

There may be such a pattern in the changes of the starry sky.......

我又发现了。。。。。。

I found out again......

3.认识春季星空中的显著星座 。

Recognize the prominent constellations in the spring sky.

狮子座位于北斗七星的南方。它的头不朝西  ，有几颗较亮的星组成弯弯的镰刀型 ，尾巴在东 ，主要由3颗星组成一个三角形 。

Leo is located in the south of the dipper. Its head is not facing west, and there are several bright stars forming a curved sickle type, with the tail in the East, mainly composed of three stars to form a triangle.

4.我们来寻找北极星 。

We're looking for Polaris.

北极星总是在正北方向 。黑夜，指南针又看不到其他辨认方向的标志是，可以利用北极星辨认方向 。

Polaris is always due north. At night, the compass can't see any other signs to identify the direction, that is, the north star can be used to identify the direction.

怎样才能找到北极星呢 ？

How can I find the Arctic star?

5.我们继续来观察、研究星空。

We continue to observe and study the starry sky.

我继续研究我选定的星座 。

I continued to study my chosen constellation.

我又要重新选定观察目标了 。

I'm going to retake my observation.

我们来预测 ：从春天到夏天 ，北斗七星会发生什么变化 ？春季的其他星座会发生什么变化 ？

Let's predict: what will happen to the Big Dipper from spring to summer? What will happen to the other constellations in spring?

6.在天空中找到北极星 ，坚持观察北极星 。继续利用观星箱观察、记录北斗七星及自己选定的观察目标的变化  。

Find the Polaris in the sky and stick to the observation of the stars. Continue to use the observation box to observe and record the changes of Beidou seven stars and their selected observation targets.
