酸是一種與鹼相反的化合物。果汁來自橘子、萊姆和檸檬都是弱酸的例子。在你胃中有許多非常強烈的酸，可以幫助你分解你所吃的食物。If an equal amount of an acid and a base that are of equal strength are dissolved or mixed in water, they will cancel each other out and produce water that is neutral. However, if there is more acid than base, the liquid is said to be acidic. If there is more base than acid, the liquid is basic.假如相等強度的酸和鹼混合溶解在水中，它們將會互相抵消並產生中性的水。然而假如酸多過鹼，這液體被稱作酸性。假如鹼多過於酸，這液體被稱作鹼性。Box 5:Scientists use a special blue paper to find out if something is an acid.

Box 1:WaxingThe science teacher was explaining the phases of the moon. During the lesson, she talked about a waxing moon.科學老師正在解釋月亮的圓缺變化。在這堂課中，老師討論了上弦月。If the moon is waxing, what is it doing?假如月亮是上弦樂，它正在幹嘛？Appearing closer in distance or position代表距離或位置是比較靠近的Appearing bigger in size or brightness代表尺寸是比較大或比較亮的Appearing smaller in size or brightness代表尺寸是比較小或比較亮的Box 3:Waxing means to increase in size, strength, or intensity. When the sun is rising in the morning, the light from the sun is waxing, or getting stronger in brightness.上弦月意思是尺寸、強度或亮度增加。當太陽在早上升起時，太陽光是增大的，或是光變

強或變亮。When the moon does not reflect any light at night, it is called the new moon. When there is a new moon, the moon is not visible in the sky. During the nights that follow, the moon begins waxing. That means the face of the moon that is lit by sunlight reflects more and more sunlight until it becomes a full moon.當月亮在晚上無法反射任何光線時，它被稱作新月。當有新月時，天空中的月亮是無看到的。在接下來的幾天晚上，月亮慢慢變大。這意思是月亮可以反射出越來越多太陽光直到它變成滿月。

Wedges are objects that are slanted or pointed.楔形物是一種很簡單的機器。楔形物是一種斜或突出的物體。A wedge makes it easier to push or pull things. For example, the point of a nail is a wedge that makes it easier to pound the nail into a board. A sharp side of a knife is a wedge that makes it easier to cut things.楔形物可以更簡單的推動或拉動物體。舉例來說，鐵釘的尖端就是一種楔形，它可以讓鐵釘更簡單敲進板子上。刀子的尖端就是楔形，它可以讓切東西變得更簡單。The wedge has been in use for over 9,000 years. In ancient Egyptian quarries, bronze wedges were used to break away blocks of stone needed for construction. Some Native Americans used antler wedges for splitting wood.楔形物已經被使用超過 9000年。在古埃及礦場中，銅楔形物拿來被使用在建築上需要敲開石頭時。一些美國印地安人使用楔形切開木頭。

But scientists have a different definition of work.當大部分的人討論工作時，他們意思是做某些事賺錢或是得到好成績。因為科學家對工作

有不同的定義。In science, work means to use force over a distance. The greater the force or the further the distance, the more work is being done. So, taking out the trash or mowing the lawn is a lot of work. But writing a report does not take very much work. That's because it does not take much force to push a pen or to press keys on a computer.在科學上，勞動意思使用力越過距離。力量越大或越遠的距離，越多的勞動需要完成。所以丟掉垃圾或是割草是需要很多勞動的。但寫報告不需要太多的勞動，這是因為它不需要太多的力去推筆或按鍵盤。Box 5:Which of the following requires the most work?下列哪一項需要很多勞力？A Doing research using a computer用電腦做研究B Playing cards玩牌C Pushing a baby in a stroller推有娃娃在裡面的娃娃車D Riding a lawnmower騎割草機Box 8:Well done!

Yeast is used to make many different foods and beverages. You may have seen someone adding yeast to bread dough. That is because yeast gives off carbon dioxide, which makes the bread rise.酵母一種單細胞生物，它不需要空氣去成長和繁殖。酵母拿來使用在不同食物和不同飲料上。你可能有看過有些人把酵母加進麵粉團。這是因為酵母放出二氧化碳，可以使得麵包膨脹。Yeast can also be used to make a liquid called ethanol. Ethanol is used to make gasoline for cars and trucks.酵母也可用在製造一種叫做乙醇的液體。乙醇是拿來製作給車或貨車使用的汽油。

Another way to think of power is that it is the amount of energy that is produced or used in a given amount of time. Different tasks require different amounts of power. For example, it takes much more power to hammer a nail into a piece of wood than to file your fingernails.功率是工作完成的速率。另一個想到功率的方式是在一個時間內產生了多少的能量或使用多少的能量。不同的任務要求不同量的功率。舉例來說，敲打一根鐵釘讓它釘到木板上是比銼指甲花更多的功率。When the steam engine was first invented, its power was compared to the work a horse could do. That is why the term horsepower is still used today to describe how powerful a car engine is. The amount of power used by a light bulb, on the other hand, is measured in watts. A light bulb that uses 60 watts is more powerful and brighter than a light bulb that uses 45 watts.

當蒸汽機被發明時，它的功率是與一匹馬的功率相比。這就是為何馬力仍然使用在今天形容車子的引擎有多大馬力。功率的總和也會用在燈泡，另外一方面就是用瓦特衡量。使用60瓦的燈泡是比使用 45瓦的燈泡要有大功率與亮。Box 5:Which of the following activities would require the least amount of power?下列哪個活動可能需要最小的功率？A Riding a bicycle騎腳踏車B Taking a jog慢跑C Playing basketball打籃球D Reading a book閱讀Box 8:Well done!
