外研版Book1Module5如何寫實驗報告

1、如何寫實驗報告【寫作任務(wù)】請你根據(jù)下列提示，寫一篇英語短文介紹壯觀的“火山”實驗, 在英語口語課上與大家分享。實驗?zāi)康模河^察沸水和冷水的對流實驗器具：空瓶、紅墨水實驗方法：1. 在空墨水瓶里滴入10滴紅墨水；2. 注入沸水，扭緊瓶蓋，把它放入水槽里；3. 向水槽里倒入冷水，浸過瓶口約5厘米；4. 輕輕地旋開瓶蓋。實驗結(jié)果：瓶內(nèi)的紅水慢慢上升噴向水面。結(jié)論：沸水和冷水發(fā)生對流時，沸水上升，冷水下降。注意：1. 詞數(shù)100左右（開頭已給出，但不計入總詞數(shù)）；2. 參考詞匯：火山爆發(fā) eruptionAim: To find out what may happen when boiling wate

6、od: 1. Put ten drops of red ink in the empty bottle.2. Add some boiling water to the bottle. 3. Close the cap tightly, and place it in the sink.4.
