"Where is the flag-raising platform" flagpole and shadow PPT courseware

Let’s learn the direction first

In the morning, which side does the sun rise from?

Students, point your right hand to the east. Then, which side is your left hand, front, and back?

Get up in the morning and face the sun. East is in front, west is behind, north is on the left, and south is on the right.

Maps are usually drawn from north to south, left to west and right to east.

When describing the position of an object, another object needs to be selected as a reference.

Xiao Ming wants to go to the Children's Palace. Do you know how to get there?

How to get to the Children's Palace?

First go east and then north, and you'll be there

If Xiao Ming wants to go to the stadium, do you know how to get there?

How do you tell the direction between north and east?

To express the direction more accurately, in addition to the four main directions of east, south, west and north, compasses are usually engraved with: southeast, northeast, southwest and northwest.

Give it a try:

1. Identify the eight directions in the classroom.

2. Sit on your seat and say: Who are your classmates from the southeast, northeast, southwest, and northwest?

To the northeast is ( )

To the southeast is ( )

To the northwest is ( )

Operation:

In daily life, in addition to using a compass to identify the direction, what other ways can we identify the direction?

1. Look at the number of trees

The south side of the tree receives sunlight for a longer period of time and has denser branches and leaves; the north side of the tree receives less sunlight and has sparse branches and leaves.

2. Use the watch to identify the direction

On a sunny day, you can use your watch to tell the direction. For example, it is ten o'clock in the morning. 10 divided by 2 is 5. Point the 5 scale on the watch towards the sun. The direction pointed by 12 is true north. The formula to remember is "time is divided in half to the sun, and the 12th point is to the north."

3. Pay attention to the ant nest

Ant nests under trees and near shrubs are always to the south of the trees and shrubs. Many animals in nature are very smart and they will choose to build their nests facing south.

4. Look at the moss

Moss likes a dark and humid environment. In places with many rocks, you can also find a striking rock to observe. The moss-covered side of the rock is the north side, and the dry and bare side is the south side.
