Anemometer Course Presentation

 The wind is a common natural phenomenon, and it is also a natural phenomenon that children are very interested in. From the formation of the wind, the types of the wind to the role of the wind, it contains a very rich scientific knowledge. Let children understand these knowledge simply, it can open up their horizons, enrich their knowledge, and enhance their scientific literacy. By making "manufacturing wind", it can also cultivate children's practical ability, thinking ability, coordination ability, etc., thus developing children's potential.

 Activity Objectives:

1. Understand the causes, characteristics, and types of wind.
2. Make your own wind.
3. Feel the power and intensity of the wind.
Inductive summary, analyze the types of wind

1. Prepare for the activity by looking for different types of wind in our daily lives.
Now, please tell us, what winds have you all found?
(1) Air conditioning blows cool air.

It is very cold when there is a strong wind.

(3) Opening the refrigerator will feel cool.

Typhoon

After Mom sprays the perfume, there is a fragrance in the air.

The wind in the hair dryer is very hot.
Teacher's Summary: In life, there are many different kinds of wind, and children have found these winds in different ways and places. The wind is a large family, and there are many types of wind in nature that can be classified by level, season, and direction. For example, a level of cooking smoke drifts with the wind, a level of wind blows face, a level of wind makes leaves move and colorful flags float, a level of wind blows away paper pieces...; The wind in summer is warm and humid, and the wind in winter is cold and dry.
Please let the children judge the level of the wind based on the nursery rhyme.
2. The humidity and wind direction of the experimental wind.
Blow the spray of water from the fan towards the children, so that everyone can feel the cool and damp feeling of the wind, and guide the children to recall the characteristics of the wind when it rains (a little cool, with a wet feeling on the body). Then use a hair dryer to blow towards the children's heads, feeling very hot and dry!
Light a candle and have the child hold it at the window, doorway, and hallway, observing the direction of the flame, and then tell where the wind is blowing from.
Teacher's Summary: Children have learned how to judge the strength of the wind, the direction of the wind, and the dryness or moisture of the air. These are experiences that people have summarized from their daily lives, and they will play an important role in your future lives.
Further Question: Do you know how the scientists who are responsible for weather forecasts predict the wind's strength and direction? (Anemometer, wind vane) 3. Make a wind vane by yourself.
(1) Fold the two ends of the red waxed paper strip and cut the ends to form a head, and then stick it to the thin wooden stick.
Insert the straw into the bottle filled with sand, and then insert the thin stick into the straw.
Section Four: Exhibition of Works Encourage children to display their own made wind direction indicators, and then arrange the children's works to be displayed collectively.
Activity Extension:
Take the children to observe the wind direction with a homemade wind vane in the outdoor.
