　　a wind vane or weather vane is an instrument which helps in determining the direction of the wind and helps in weather forecasting. Not only is it one of the oldest, but also one of the simplest weather forecasting instruments to have been invented. In fact, it is quite simple to make on your own; all you need are a few things–most of which are readily available at homes–like a drinking straw, pencil with an eraser attached to it, card paper, straight pin, and a box or a paper cup.

Step-by-step Instructions to Make a Wind Vane

The wind vane that we are referring to here is not the state-of-the-art equipment that you see at the weather station, or one that you see on tall buildings, but a simple homemade vane which is meant to help you understand the basics of wind as an element of nature.

To begin with, it is important to know that one side of the wind vane is always slightly bigger than the other. It is specifically designed in this manner to ensure that it comes in proper contact with the wind. When the wind blows, the side which is bigger is pushed by the wind, which leaves the narrower side, i.e., the pointer or arrow, pointing towards the direction from which the wind is blowing.

Step 1

Take the card paper, draw the head and tail of the wind vane on it, and cut out these portions using a scissor.

Step 2

Take the drinking straw and give it small cuts on either end (as shown in the illustration below.

Step 3

Insert the head and tail of your wind vane in the cuts that have been made in the straw.

Step 4

Take the straight pin, pierce it through the drinking straw in the center and attach the straw to the eraser on the pencil. Before you move ahead, make sure that the straw is turning smoothly.

Step 5

Make a base for your wind vane using a paper cup or box. You simply have to pierce a hole in the paper cup and place the pencil in it.

The Water Cycle

Step 1

The sun happens to be the driving force of the water cycle. It heats up the water in seas, rivers, lakes and glaciers, which evaporates and rises up in the atmosphere. Water is also evaporated through plants and soil through a process called transpiration. This evaporated water is in the form of water vapor, which cannot be seen with naked eyes.

Step 2

This water vapor then comes in contact with air currents, which take it higher into the atmosphere. After reaching cooler temperatures, the water vapor condenses to form clouds, which contain millions of tiny droplets of water.

Step 3

These clouds move all round the globe and grow in size, collecting more water vapor on their way. When it becomes too heavy for the clouds to hold anymore water vapor, they burst and the droplets of water fall back on earth in the form of rain. If the atmosphere is cold enough, the form of precipitation changes from rain to snow and sleet.

Step 4

In the last step, rain or melted snow flows back into water bodies like rivers, lakes, and streams. Rainwater is also soaked up by the soil, through a process called infiltration. Some of the water also runs off the surface or seeps in the ground, which may later be seen as groundwater or freshwater springs. Eventually the water reaches the oceans, which are the largest water bodies and the biggest source of water vapor.

The water cycle happens to be a simple cycle, yet involves a lot of processes. Some of the processes that are involved are:

Evaporation:

When the heat of the sun causes water to turn to water vapor, it is known as evaporation.

Condensation:

As the water vapor moves higher in the atmosphere, it cools down due to a decrease in the temperature. On cooling, the water vapor condenses to form tiny droplets of water. This process is known as condensation.

Precipitation:

The tiny droplets of water that are formed as a result of condensation keep on accumulating in the clouds. When a cloud can no longer accommodate any more water droplets, the water is released from them in the form of rain, hail, sleet, or snow.

Run-Off:

The water that falls back to the surface of the earth either stays on the surface of the earth, or flows off the surface into water bodies like rivers, lakes and reservoirs. This flow is termed as run-off.

Transpiration:

Plants absorb water from the soil and transport it to the leaves via the stem. When this water evaporates from the leaves and stem, it is termed as transpiration.

Infiltration:

When the water on the surface of the earth seeps down the ground, it is called percolation or infiltration. It later forms aquifers in low-lying regions.

These were the major steps and processes involved in the water cycle. A cycle – from water vapor in the air to precipitation as rain – takes about nine days to complete.

When I was pregnant，you were a fetus inside me,you grew in an area called the womb where I gave your everything you need until you are big enough to come out.Look at this picture,the doctor used a special camera made it for us when you were a three-month-old fetus.It was the first picture of your life.Look at these colorful pictures.The doctor made them at the fifth month when I expected you. I saw your face for the first time in these pictures.I felt so excited at that moment.

I copied the precious pictures and cut them down.We pasted one picture on a pregnant woman patten.And the picture.💝

Of couse,we hug eachother and sang You are my sunshine.

Ultrasound超声 美音/'ʌltrəsaʊnd/

Nurse: Follow me. We're about to finish your check-up with an ultrasound.

Ultrasound比B ultrasound这种说法更常用，读作 [ˈʌltrəsaund]。

Child: Is this what the doctor uses to see a baby still in his mommy's tummy?

Mom: Yes, it is. We have a copy of my ultrasound of you inside my tummy!

我们留着一份你在妈妈肚子里时候的超声报告呢！

Nurse: Lie down on this table, please. 躺在这个台子上。

Now, pull your shirt up to show your stomach. 把衣服撩起来，把肚子露出来。

I'm going to put some jelly on, so the ultrasound can read the inside of you properly.

我要给你抹一些胶凝，这样超声就能正确地读取你身体内部的信息了。

如果要特指耦合剂，用coupling jelly，coupling 读作 [ˈkʌpliŋ]。N. 连接；连接器（尤指列车等的）车钩，挂钩

Child: That tickles!好痒！

Nurse: Haha, I bet it does. Try to hold still, we are almost done.

我就知道你会痒。再坚持一下马上就好了。

All good. Let's clean your stomach and you will be good to go.

都挺好。把你的肚子清洁一下，你就可以走
