Box 1:Carbon CycleThe carbon cycle has been a topic of discussion among scientists.碳循環在科學界已經是一個討論的主題What is the carbon cycle?什麼是碳循環？The movement of carbon around different parts of Earth.碳在地球不同部位中移動The movement of carbon from the air into our bodies.碳的移動是因為來自空氣進到我們的身體The movement of carbon from burning fuels into the atmosphere.碳的移動是燃燒燃料進到大氣層Box 3:The carbon cycle is the exchange of carbon through the atmosphere, soil, oceans, sediments, and the interior of Earth. It is called a cycle because volcanoes and thermal vents release carbon back out into the atmosphere to repeat the exchange over and over again.碳循環是碳透過大氣層、土壤、海洋、沉澱物並和地球內部交換而來。它被稱作循環，因為火山爆發和熱的排氣口會釋放碳，退回大氣並重覆不停的交換。In the atmosphere, carbon exists as carbon dioxide and is important in supporting life. Forests store carbon in trees above ground and in soil below ground. As carbon cycles through oceans, some living things in the oceans use the carbon to make hard body parts like shells. Since oceans cover almost three-fourths of Earth's surface, the oceans are a major part of the carbon cycle.在大氣層中，碳存在在二氧化碳中，且它是支持生命很重要的部份。地上的森林在樹上儲存碳且也儲存土壤下。當碳循環透過海洋時，一些海洋生物使用碳製作成身體的部份硬的部份，就像貝殼。因為海洋覆蓋了四分之三的地球表面，海洋是一個主要碳循環的部份。

Box 1:Cause-and-Effect RelationshipIn talking with a friend about how it always seems to rain on picnics, Hilda said there was no cause-and-effect relationship between rain and picnics.與朋友聊天聊到有關於在野餐時總是看起來會下雨，Hilda說下雨和野餐是沒有因果關係。What is a cause-and-effect relationship?什麼是因果關係？When something always seems to happen當某物總是發生When something happens as a result of something else當某事發生是因為別的東西的結果When there is no pattern to things that happen當沒有模式的事情發生Box 3:A cause-and-effect relationship is when something happens as a result of a something else happening first. For example, when the temperature outside becomes very cold, water will turn into ice. Therefore, there is a cause-and-effect relationship between temperature and water turning into ice.因果關係是當別的事情發生時某事會跟著發生。舉例來說，當室外溫度變得非常冷時，水會變成冰塊。因此，這是有因果關係在氣溫與水變成冰塊的。Many discoveries in science are best understood by describing their causes-and-effects. When scientists see a connection between two things, they try to show a cause-and-effect relationship. For example, below is a photo of a parched, or extremely dry, stretch of land. The land is parched because there has been no rain for a long time. The cause is "no rain." The effect is "parched land." 許多科學上的發現是因為理解了因果關係。當科學家看兩件事的關聯，他們試著表現因果關係。舉例來說，下面這張是展現非常炎熱，極度乾燥的土地。這土地是乾燥的因為已經沒有下雨很久了。這個因就是”沒有雨”，果就是”乾燥的大地”。

Box 1:

Climate ChangeEarth has experienced climate change since before anything lived on the planet.地球有氣候變化的例子是自從萬物住在這個星球上。What is climate change?氣候變化是什麼？Changes in weather over long periods of time氣候改變是經過長時間的Changes in weather from one season to the next氣候的改變是從一個季節到另一個Changes in weather during one day一天之內可以有氣候改變Box 3:Climate change is a change in long-term weather patterns. For example, increases or decreases in temperatures around the world over many years would signal a climate change. When dinosaurs were living, Earth was much warmer than it is today. Over the millions of years since dinosaurs became extinct, Earth has gotten colder due to climate change. Today, Earth may be going through another period of climate change, but the question is still to be studied.氣候改變是氣候長時間改變的模式。舉例來說，經過非常多年後，全世界的氣溫上升或下降將會為顯著。當恐龍還在生存時，地球是比現在還溫暖的。經過恐龍滅絕千萬年之後，地球開始並冷因為氣候變化。現在，地球可能正在度過另一個氣候變化，但這問題仍然還在研究中。The graph below shows climate change in the Antarctic region using three different models. The first two models reflect changes in temperature at two different locations over the last 450 thousand years. The third model shows changes to the ice volume over the same period of time.以下的圖表表示在南極州的氣候變化，使用了三種不同的模式。其中兩個是反映是氣候變化在兩個不同的地區在過去的 450千年。第三個是展示了在同時間內結冰量的變化。

Humidity is the amount of water vapor, or moisture, in the air. When there is high humidity it often rains and reduces the amount of water vapor in the air.濕度是水蒸氣或空氣中的水份的總量。當有高度濕度時，它通常會下雨和減少空氣中的水蒸氣總量。Humidity also changes with the temperature. Keeping the humidity of the air lower by using an air conditioner in the summer helps people feel more comfortable. At high humidity, perspiration (sweat) does not leave the skin quickly, so we feel hot and sticky. In the cold winter months, the air is much dryer and the low humidity can make a person's skin feel very dry.濕度也改變了溫度。讓空氣中的濕度降低在夏天可以使用冷氣機幫助人們感覺到比較舒適。在高的濕度下，汗是無法快速離開皮膚的，所以我們感覺到又熱又黏，在很冷的月份中，空氣是非常乾燥並有較低的濕度可以讓人的皮膚感覺非常乾。Box 5:In which of the following sentences is the word humidity used correctly?下列哪個句子使用濕度這個字是正確的？A When the humidity is high outside, it often rains.當外面的濕度是高的，它通常下雨。B When the humidity is low outside, it often rains.當外面的濕度是低的，它通常下雨。C The humidity in the air smelled like smoke.空氣中的濕度聞起來像煙D The humidity in the air caused strong winds.空氣中的濕度引起強烈的風Box 8:Well done! Your answer is correct.非常好！你答對了The correct answer is A: When the humidity is high outside, it often rains.正確答案是 A: 當外面的濕度是高的，它通常下雨。Box 12:Another way to think of humidity is dampness of the air.濕度的另一種想法就是空氣的潮溼度Word: Image影像Word ID: 700033Strand: 2Topic: [Light Behavior][光學]Used: [SG2][SH2]

This means an object that is not moving will not start moving without a force that makes it do so. It also means that an object will move in a straight path at a constant speed unless a force acts on it.

慣性是物體改變移動時的阻力。這意思是靜止的物體無法開始移動因為沒有讓它移動的力量。它也意即有一個物體將在這個直線上等速前進除非有一個力量能讓它停下。A seat belt is designed to counteract the effects of inertia and keep you safe when you are in a car. If the car in which you are riding comes to a quick stop and you are not wearing a seat belt, you will continue to move forward and hit the windshield or dashboard. A seat belt keeps this from happening.安全帶是設計去取消慣性的效應且當你在車子裡時保護你的安全。假如車子突然急停時，你又沒有繫上安全帶，你將會繼續往前移動並撞上擋風玻璃或汽車儀表表。安全帶防止這些事的發生。Box 5:Which of the following situations is an example of inertia?下列哪個狀況是慣性的例子A Falling forward when you trip on something當你失足時往前跌倒B Being pressed against the seat in a car when your mom steps on the gas pedal當你媽媽踩油門的時候，身體會被車子的安全帶勒緊C Books falling off the car seat when your mom stops the car suddenly當你媽媽突然把車停下時，書掉落在車椅上D All of the above以上皆是Box 8:Well done!
