每年DSE BIO都必會出實驗題目,但呢類題目偏偏係唔少同學既死穴!到底有咩溫習實驗題目嘅方法?
1. 搞清楚實驗嘅基本concept同definition
你一定一定要明白實驗常用嘅terms: experimental set-up, control set-up, independent variable, dependent variable, limitation, source of error...如果連呢堆嘢都搞唔清,就好難去理解實驗背後嘅principle,更何況係識答問題!另外,仲要學下點樣去describe result同make conclusion。如果上面嘅基本概念都未搞掂,我有個網上課程專攻呢個題型可以幫你極速pick up翻呢個題型架🗣
2. 開一本實驗題型筆記簿,畫低最常考嘅實驗同佢嘅variation
DSE實驗最熱門嘅課題都係個幾個:respiration, photosynthesis, transpiration...等等,呢堆課題都會比較多實驗。大家可以嘗試做CE嘅時候,幫翻堆實驗分類、將佢地塞落唔同topics。慢慢你會發現雖然有d實驗set-up係完全唔同,但原來背後嘅principle都係一樣😝。variation只係用來掩飾,令條題目多少少變化姐😏 而最常考嘅實驗我係個course入面都會逐個同大家KO🗣
3. 搵下同抄低每個實驗set-up嘅共通點
大家要睇熟某個特定既environment係點set-up, e.g 我要點樣remove CO2? 我要點樣去prevent heat loss to surrounding? 我要點樣remove O2? 可能好多讀Bio同學仔都冇讀chem/phy, 對於其他chemicals/基本set-up完全唔熟。所以大家要搵定以上堆environment點set-up, 睇到條題目先會理解到。而家有題目甚至會要求同學自己design成個set-up🤦🏻♀,如果連呢d都搞唔熟,又點自己畫一個?📝 當然唔止以上呢堆environmental factor, 而我個course仲會有個table比大家跟住背🗣
