介绍目标: “Today, we are going to create a volcano eruption! First, we need to build our volcano.” (“今天,我们要制造一次火山喷发!首先,我们需要建造我们的火山。”)
制作火山锥:
“Let’s place the empty bottle on the tray. This will be the crater of our volcano.” (“我们把空瓶子放在托盘上。这将是火山的喷发口。”)
“Now, we will use clay or play dough to mold and shape the slopes of the volcano around the bottle.” (“现在,我们用黏土或彩泥来塑形,在瓶子周围做出火山的斜坡。”)
“Make sure you don’t cover the opening of the bottle!” (“确保不要盖住瓶口!”)
第二步:配制“岩浆” Prepare the “Lava”
添加基础成分:
“Now, let’s prepare the lava! First, pour some warm water into the bottle until it’s about one-third full.” (“现在,我们来准备岩浆!首先,往瓶子里倒一些温水,到三分之一满。”)
“Add two spoons of baking soda. This is our base.” (“加入两勺小苏打。这是我们的碱。”)
“Now, let’s add a few drops of red food coloring and a squirt of dish soap. The soap will make the foam thicker and more bubbly!” (“现在,加入几滴红色食用色素和一点洗洁精。洗洁精会让泡沫更稠、充满气泡!”)
“Use the spoon or stirrer to mix everything together gently.” (“用勺子或搅拌棒把所有的东西轻轻地混合在一起。”)
第三步:引发“喷发” Trigger the Eruption
营造氛围:
“Our volcano is ready! Are you ready for the eruption? It might get messy, so stand back a little!” (“我们的火山准备好了!你准备好迎接喷发了吗?可能会有点乱,往后站一点!”)
倒入醋:
“Now, for the magic! Quickly pour the vinegar into the crater!” (“现在,神奇的时刻到了!迅速把醋倒进喷发口!”)
“Watch carefully! What do you observe?” (“仔细观察!你观察到了什么?”)
第四步:观察与描述 Observation & Description
在孩子兴奋的同时,引导他/她用英语描述所见现象。
“Look! The lava is bubbling up and overflowing!” (“看!岩浆正在冒泡,并且溢出来了!”)
“It’s foamy and fizzy! So many bubbles!” (“它是多泡沫的和嘶嘶作响的!好多气泡啊!”)
“The reaction is very powerful!” (“这个反应非常剧烈!”)
“Can you hear the fizzing sound?” (“你能听到嘶嘶声吗?”)
