1.1 背景知识
1.1.1 植树节

1.1.1.1 植树节的英文是Tree Planting Day吗？

其实，外国（特别是美澳）并不这样表达，而是用Arbor Day。

arbor美 /'ɑrbɚ/ 英 /'ɑːbə/

朗文词典对arbor的解释是：a shelter in a park or yard made by making plants grow together on a frame shaped like an arch，即“〔公园或院子里长满蔓藤的〕棚架，藤架”。这个词来自拉丁语，本是“树”（tree）的意思。

1.1.1.2 中国的植树节是3月12日

很多国家都有自己的植树节。最早的植树节是美国内布拉斯加州（Nebraska）于1872年发起的。

而中国的植树节则与孙中山有关。

中国自古以来就有在清明节时节插柳植树的传统。1915年，几位林学家倡导以每年清明节为“中国植树节”。同年7月，在孙中山的倡议下，当时的北洋政府正式下令规定每年的清明节为植树节。

1925年3月12日，孙中山先生逝世。三年后的1928年，为纪念孙中山逝世三周年，国民政府举行了植树式。此后便将每年的3月12日（即孙中山逝世的日子）定为植树节。

新中国成立后的1979年，在邓小平的提议下，第五届全国人大常委会第六次会议决定将每年的3月12日定为中国植树节。

植树节起源的英文版介绍：
国外植树节的起源：
In order to protect the forests, make the environment more beautiful and maintain ecological balance, many countries in the world have set up the Arbor Day in accordance with their real situations.为了保护林业资源，美化环境，保持生态平衡，世界上很多国家都根据本国实际情况设立了植树节。

Compared to the other countries ,the United States of America was the first one to implement the tree-planting activities, which has more than 130 years old.在这些国家中，美国的植树节最早，已有130多年的历史。

On April 10, 1872, the first American Arbor Day was initiated by a journalist from Nebrask, and more than millions of trees were planted across the state of Nebraska.1872年4月10日，由内布拉斯加州一新闻记者发起美国第一个植树节。当天，内布拉斯加州全境种树超过100万棵。

中国植树节的起源：
In ancient China, there was a tradition of planting trees in the Qingming Festival. The earliest tree-planting on the roadside was initiated by a man named wei xiaokuan from shaanxi province more than 1400 years ago.中国古代在清明节时节就有插柳植树的传统，历史上最早在路旁植树是由一位叫韦孝宽的人于1400多年前从陕西首创的。

In1979,China officially designated March 12 as "Arbor Day". Encourage individuals and teams to plant and care for trees in order to protect the environment.1979年，中国正式将每年的3月12日定为“植树节”。鼓励个人和团队种植和爱护树木，保护环境。

How to Celebrate Arbor Day：

Arbor Day is a day to gather and celebrate trees and all that they do for us. It is a day to show gratitude by caring for current trees, planting new ones, and simply getting outside and enjoying the fresh air and beauty that they provide.
There are many ways to celebrate Arbor Day and to show your appreciation for trees. If you are wondering what to do to properly celebrate the occasion, here are some ways you can commemorate the holiday.
1）The best way to celebrate Arbor Day is to plant a tree or many trees!
2）Another way to celebrate Arbor Day is to donate money to an organization that plants trees, preserves rain forests, and/or works to save forest lands around the globe.
3）Volunteering in your local community to plant new trees and care for existing ones is a great way to show your appreciation on Arbor Day.
4）Educate Yourself! Read a book on trees and get a forestry degree online.
5）Simply speaking ,get outside! Go on a hike. Make a point to take in the beauty of the trees. You could even make a game out of it and try to identify the most trees.

Plant a tree重点
Here is a quick step-by-step guide to planting your new tree.
1）Dig a large hole where you want the tree to go.
Make sure the hole is at least two times as wide as the root ball and deep enough for the root ball to fit so the top is slightly above with the surrounding ground.
2）Carefully position the tree in the hole.
Be sure that tree is facing the direction that you want it to and remove any ties or burlap that came attached to the tree root.
3）Fill in the remaining space.
Add loose soil and organic matter (optional) to the space leftover. Try not to add too much to one side, forcing the tree to tilt in one direction. You want it to grow straight and tall.
4）Attach the tree to a stake.
Stick a stake into the ground and through the root ball. Then attach it loosely to the trunk of the new tree.
5）Water, water, water.
Newly planted trees require more than more established trees. Water the new tree every day for the first few weeks.

简化版本：

Step1：Select a site with enough room for roots.选择能容纳树根的足够场地。

Step2：Dig a hole in the middle of the area.在场地中间挖坑。

Step3：Put the sapling in the hole.把树苗放到坑里。

Step4：Cover the root with soil.给树根填上土。

Step5：Water the sapling.给小树苗浇水。

主办方没给水桶没法浇水，Jasper就用自己的水杯来浇水，哈哈哈

这次又是跟Vincy和Demi姐姐们一起约的，感觉入了工程，还收获了朋友，真不错….

4.1 Life cycle of silkworms

The lifecycle of a crawling worm into a moth goes through several stages.

5 Important Stages in the Life Cycle of a Silkworm

Stage 1: The Egg

This is the first stage of a silkworm’s life cycle. The female moth lays eggs which are the size of a small ink dots! The female can lay more than 350 eggs at a time. These eggs remain dormant till springtime when the warmth in the air arouses them to hatch. This happens once a year. But due to human intervention the breeding of silkworm and hatching of eggs takes place at least thrice a year.

Stage 2: Larvae

When the eggs crack there emerges a hairy silkworm. This larva stage is the one where growth takes place. Upon hatching, a silkworm is 1/8th of an inch. They feed on tender mulberry leaves. They consume large amount of these leaves for 20 to 30 days and go through four stages of molt or skin changes. The first molt is when the silkworm sheds all its hair and attains a smooth skin.

Stage 3: Cocoon

At this stage the silkworm spins a protective cocoon around itself. It is made by a single thread of silk and it the size of a small cotton ball. This, it does to protect itself from predators. This is the stage where the second molt takes place when the lava turns into a pupa inside the cocoon.

Stage 4: Pupa

This stage is the motionless stage just before adulthood. It is at this stage when people take the cocoon and plunge it into boiling water to kill the pupa and unwind the silk thread. But if they don’t the pupa rests peacefully for 2-3 weeks after which it metamorphoses into an adult moth.

Stage 5: Adult moth

The pupa changes itself into a beautiful adult moth. These moths are flightless and do not have a mouth so they are unable to consume food. Once the adult moth comes out its sole purpose is to find a mate. Within 24 hours of mating a male moth dies while the female lays eggs and then even she dies. Thus the lifecycle of a silkworm begins again.

4 Interesting Facts about Silkworm

Normally silkworms reproduce only once a year but in countries like India and China they can do so round the year because of the weather.

Silkworms is the term used for the worms called Bombyx Mori.

The salivary gland of the silkworm larvae produces the silk thread for the cocoon.

One cocoon will contain raw silk thread of 300 to 900 meters in length.

4.2 Silk

Introduction

Silk is a valuable fiber made mostly by insects called silkworms. It is used to make high-quality clothing, sheets, and other things.

Natural Silk

Silkworms are actually caterpillars, not worms. A silkworm builds a case called a cocoon around itself for protection while it changes into a moth. It makes the cocoon with silk that comes out of a tube in its head. The silkworm wraps a single long strand of silk around itself over and over again.

Some spiders also make silk. They weave silk webs to catch insects to eat. However, the silk made by spiders is too thin for making cloth.

The Silk Industry

In the silk industry, silkworms are raised from the time they are eggs until they have made a cocoon. In nature, a silkworm breaks open its cocoon to come out as a moth. Silkworms used for industry are killed with hot air or steam inside the cocoon. This way the cocoon is not damaged.

To process silk, the cocoons are first put in hot water. This softens the cocoons so the silk can be unwound. Several cocoons are unwound at the same time to form a single strand. Then several strands are twisted together to make thicker, stronger yarn. The yarn can be dyed and woven into cloth.

History

The silk industry began in China more than 4,500 years ago. The Chinese traded silk but would not tell other countries how it was made. Silk was such an important product that the trade route between China and Europe was called the Silk Road. In the ad 500s silkworms were stolen from China. Then Europeans started making silk themselves.

Today artificial fibers are often used instead of silk. But people still value silk items because of their quality. China remains a major silk producer.

Remember, the redder the berry, the sweeter it will taste. Don't pick the green or white ones. Those are not ripe yet. They still need to grow some more and turn red and sweet before they are ready to pick and eat.

记住，浆果越红越甜。不要挑绿⾊或⽩⾊的草莓。还没熟。它们还需要再⻓⼀会才会变红、变甜。

This strawberry is rotten, we can not eat it. If you eat it, your tummy will hurt.

这是草莓烂了，我们不能吃。如果你吃了它，你的肚⼦会痛的。

Good choice, it looks perfectly ripe and fresh. Excellent, you have filled up your basket.

Woo, what appetizing （ 诱人的 ) strawberries! They must be delicious! But we should wait for a moment.

喔，多美味的草莓啊！⼀定很好吃！但我们应该等⼀下。

We must wash them with fruit and vegetable wash, rinse twice with fresh water.

吃之前⼀定要⽤果蔬清洁剂清洗，然后⽤清⽔漂洗两遍。

5.3 Strawberry Pollination 草莓授粉

Inside each flower are the male and female parts. What makes a new fruit grow?

每朵花⾥⾯都有雌雄两部分。新⽔果是怎么⻓出来的？

The male parts are called stamens ， stamens is dad ， look, these are many stamens.

雄性部分叫雄蕊，雄蕊就是爸爸，看，这些都是雄蕊。

Many daddy stamens are around mummy pistils. They sticking out in the circle.

很多雄蕊围绕在雌蕊周围。他们在圆圈⾥冒出来。

At the Top of each daddy stamen ，pollen is made. See the yellow powder.

在每个雄蕊的顶部，都有花粉。看⻩⾊的粉末。

They are pollen, daddy stamens can produce pollen！

它们是花粉，雄蕊可以产⽣花粉！

So at the center of the flower, there are pistils, there are mommy！

同理，在花的中⼼，有雌蕊，这些就是雄蕊！

The female part of the flower is called pistil（mommy）.

6. 农场采摘

本来以为去农场还有可能可以采摘点农作物，于是找了这个视频，结果形程很匆忙，哈哈哈😄

PS: 植树活动去年参加过一次，今年惊喜地发现孩子植树的过程几乎也都知道了，用词也算准确。。。至于采草莓部分，清英主题课里好多次反复学过植树学的东西，所以孩子复习起来特快。。。以前ft拓展好难，现在觉得好像做多了感觉也没那么难了哈。。。

日复一日地坚持，妈妈和孩子们都进步了，当然爸爸也进步了，例如现在外教课爸爸下班的话都是爸爸带孩子预习然后带孩子上课，于是妈妈才有时间陪妹妹和抽空打个卡哈。。。。
