海尼曼的理解閱讀終于挑戰(zhàn)N級(jí)了，就著All about volcanoes這本書(shū)，做了2個(gè)小實(shí)驗(yàn)，通過(guò)實(shí)驗(yàn)，讓BB輸出關(guān)于volcano的特性，并按書(shū)的內(nèi)容提問(wèn)了一些問(wèn)題來(lái)梳導(dǎo)理解，感謝娃，令我這個(gè)文盲媽也懂得了關(guān)于火山的一些常識(shí)哈！ ???? <font color="#167efb"><b>Experiment 1 -- Coca cola burst</b></font> 這個(gè)實(shí)驗(yàn)相對(duì)簡(jiǎn)單，只需要準(zhǔn)備一瓶可樂(lè)或雪碧就好，一共做了3次，每次BB都玩得非常開(kāi)心！<div>通過(guò)這個(gè)實(shí)際，讓BB理解了2種火山的區(qū)別，如何得知火山準(zhǔn)備噴發(fā)，噴發(fā)的3種表達(dá)方式！</div> ???? <font color="#167efb"><b>Experiment 1 -- Vinegar burst</b></font> <font color="#ed2308"><b>Part 1: 實(shí)驗(yàn)過(guò)程，讓BB懂得各種實(shí)驗(yàn)道具名稱(chēng)，實(shí)驗(yàn)過(guò)程，為什么會(huì)噴發(fā)</b></font> What we need: <div>containers (such as a volcano, some test tubes)容器，比如小火山或者試管 </div><div>a tray 托盤(pán), </div><div>vinegar 白醋, </div><div>a funnel 漏斗, </div><div>baking powder/soda 食用小蘇打<br>food colorings食用色素,</div><div>goggles 護(hù)眼鏡, Measuring cup. 量杯<br>Look at this. It looks like water, but.. It's not water, so don't drink it. You can smell it, and guess. Haha! It is sour, isn't it?<br>This is called vinegar. Vinegar is sour. Here is a tray<br>This tray is very important because you want to keep your table clean.<br>We also need some baking powder, okay.<br>Alright, so the first step is open our baking powder. You can do it carefully or I may help you .Just take that off, just like this. And then open it up. Make a little crase there so you can pour easy. Ok, here we go.<br>You don't need too much. Ok, that's enough.<br>Then next part is we must put in color to make our experiment more exciting.<br>When a volcano erupts, lava flows out.<br>Do you know what color is lava?<br>The lava from the volcano is red. we put a few little drops of red. Maybe four drops are enough. Alright, now.<br>We've got our baking soda into the volcano. We've got out color put inside.<br>Now it will erupt. We take our vinegar.<br>Are you ready?<br>We are going quickly pour the vinegar into the volcano. Ready? Here we go!<br>my god. Amazing! So beautiful.<br>They look like a real volcano.<br>Do you like it? Yes. I like it.<br>Mommy, please tell me, why there are so many red bubbles, like the lava?<br>Well. That's very simple.<br>You see when the baking soda and the vinegar mixed together.<br>They create a chemical reaction.<br>And that causes the bubbles to come out. Like the lava.<br>We added the color <br>So that our bubbles look more colorful and more beautiful.<br>We don't want to just see clear lava, right?<br></div> <font color="#ed2308"><b>Part 2: 利用實(shí)驗(yàn)，讓BB理解火山的定義、組成，2種火山的區(qū)別，如何得知火山準(zhǔn)備噴發(fā)，噴發(fā)的3種表達(dá)方式， 夏威夷島的形成過(guò)程</b></font> ???? <b><font color="#167efb">Reading discussion </font></b> 1.
