Well this month we’ll explore the three states of matter, liquid, solid and gas.Now today we are going to make a super cool parachute.<div>這個(gè)月，我們將要探索物質(zhì)的三種形態(tài)，液態(tài)，固態(tài)和氣態(tài)。<br>那么今天我們要制作一個(gè)超級(jí)酷的降落傘。<br><br>做這個(gè)實(shí)驗(yàn)，你需要一個(gè)降落傘。<br>For this experiment, you’ll need a parachute.<br>A plastic container.一個(gè)塑料容器。<br>An earth kite.一個(gè)地面風(fēng)箏。<br>Paint.顏料<br>A paintbrush.一根筆刷。<br>A bottle cap.一個(gè)瓶蓋<br>A piece of black paper. 一張黑紙<br><br>Now you can see our parachute here is very, very white.OK. We want to make this parachute more beautiful.<br>現(xiàn)在你們可以看到我們這兒的降落傘非常非常的白。好的，我們想讓這個(gè)降落傘變得更漂亮。<br><br>So first thing we can do is we lay it out nice and flat like this, okay.And then we have our paint.<br>那么首先我們要做的是將它好好的鋪開(kāi)，像這樣鋪開(kāi)，好的。然后我們用顏料<br><br>So you can see here I put a piece of paper down.this is just to make sure I don’t get any paint on the table or anywhere else.OK. We want to make sure everything stays clean.<br>那么你們可以看到我在這兒放了一張紙。這是為了確保我不會(huì)將顏料弄到桌子或別的地方。好的，我們要保證讓一切東西都干干凈凈的。<br><br>And we also have our brush.</div><div>我們還有筆刷<br>And now we can find any things of different shapes in our house,for example,a little cap,maybe this is from some toothpaste or something.And you can see it’s a circle.<br>You can find other things in your home to put onto your parachute.<br><br>所以，小朋友們，你們可以在屋子里找到一些物品<br>So you can find some things in your house, kids.<br><br>So I’ll show you here. I think the first color I will use is green.So we just open up the green then we put it on the paper.<br>所以我們只要打開(kāi)綠色，然后我們將它放在紙上。<br><br>Then you take your little circle cap.And you can just brush some green on there.And then we’re just gonna make a circle right on the parachute.And you can make your parachute anywhere you want, right？<br>然后用你的圓形小蓋子。然后你只要在那兒刷上綠色。然后我們就可以在降落傘上印出一個(gè)圓形了。你可以在你的降落傘的任何地方印出圖形，對(duì)嗎<br><br>So I’m just gonna make little green dots or you can make lines.you can color everything whatever you want to do<br>所以我要做出綠色的小點(diǎn)兒，或者你們可以畫(huà)線段。你可以將所有東西都涂上顏色，想怎么做就怎么做<br>OK, now, make sure you have some water so you can clean your brush cause you don’t want to get green paint in another color.<br>好的，現(xiàn)在，要確保你準(zhǔn)備了水，這樣可以將筆刷洗干凈，因?yàn)槟銈儾幌胱尵G色將別的顏色染色。<br><br>And you can also have some wet wipes.You can wash off your little cap around like this.<br>你們也可以用濕紙巾?？梢詫⒛愕男∩w子擦干凈。</div><div><br></div><div>So you can use circles or triangles, anything you want<br>所以你可以用圓形或者三角形，任何你想用的<br><br>now you can see we have finished our beautiful parachute.You can see the colored circles are all over there.And you have to make sure that after you paint it, you let the paint dry.<br>你們可以看到上面全部印滿了彩色的圓形。你們要確保當(dāng)涂好顏料后，要讓顏料變干。<br><br>OK, so that when you touch it,See I can touch it and there is no paint on my hand.<br>好的，所以當(dāng)你摸它的時(shí)候,看，我可以摸它，我的手上也沒(méi)有顏料。</div><div><br></div><div>And now,look at this.This is our little earth kite.OK I‘m just gonna open that up to show you.</div><div><br></div><div>Can you figure it out?</div><div>Wow.you make it.Good thinking.Can it fly?<br>Then we have a long string here.<br>然后我們這兒有一根長(zhǎng)線。<br><br>So you can play with that.And just pull it.You pull that, and it just flies in the sky.<br>Now I think we can play together.So you can take your earth kite.and I can take my parachute.<br>You can throw your parachute up in the air, and watch it rise up into the air and then it will drop down nice and slow.And you should catch it before it can land on the ground.OK. So you can throw this as high as you want.<br>你可以將你的降落傘拋向空中,看著它在空中升起來(lái), 然后慢慢的落下。你應(yīng)該在它落到地上之前抓住它。好的，那么你可以想扔多高就多高。<br><br>Why does a parachute work?<br>為什么降落傘會(huì)這樣？<br><br>When the parachute opens,it will fill up with air and become very big and wide.<br>當(dāng)降落傘打開(kāi)后, 它會(huì)充滿空氣，變得很大很寬。<br><br>It then creates drag which slows us down.Without drag we’ll fall very fast.<br>然后它就會(huì)產(chǎn)生阻力，讓我們能夠緩緩下降。沒(méi)有阻力的話，我們就會(huì)快速地落下去。<br><br>The bigger the parachute, the slower we’ll fall.because the drag is increased.<br>降落傘越大，我們就落的越慢.因?yàn)樽枇υ黾恿恕?lt;br></div>
