第 1 題 In mathematics, what is the result of adding two or more numbers called?
在數學中，把兩個或多個數相加的結果叫什麼？
『Sum』指加法運算的結果，例如 3 + 4 = 7，7 就是 sum。
'Sum' is the result of addition, e.g., 3 + 4 = 7, so 7 is the sum.

哪個術語表示『減法的結果』？
『Difference』是減法的結果，例如 9 - 5 = 4，4 就是 difference。
'Difference' is the result of subtraction, e.g., 9 - 5 = 4, so 4 is the difference.

在科學實驗中，你故意改變的變量稱為______。
『Independent variable』是實驗中由實驗者主動改變的變量；『dependent variable』是隨之變化的結果；『control variable』是保持不變的變量。
The 'independent variable' is the one you change on purpose; the 'dependent variable' is the outcome that changes; a 'control variable' is kept constant.
第 4 題 Which phrase best describes 'a fair test' in science?
哪個短語最能描述科學中的『公平測試』？
公平測試只改變自變量，其他變量保持不變，這樣才能確定因果關係。
A fair test changes only the independent variable while keeping all other variables constant, so you can identify cause and effect.
第 5 題 In a science report, which section would you write 'The plant grew taller in sunlight'?
在科學報告中，你會把『植物在陽光下長得更高』寫在哪一部分？
『Result』部分用來描述實驗中觀察到或測量到的數據和現象。
The 'Result' section describes the data and observations from the experiment.
第 6 題 Which of the following is the best definition of 'volume' in science?
