Well this month we’ll explore the three states of matter, liquid, solid and gas.<br>Today we’re gonna do something very fun.We’re gonna explore magnetism.<br>For this experiment, you’ll need iron fillings, corn starch, glue, a magnet, water.<br>做这个实验，你需要铁屑，玉米淀粉，胶水，一个磁铁，水<br>A popsicle stick, a bottle cap.<br>一根冰棍棒， 一个瓶盖。<div>So we have something here called iron filings.So you can put the magnet even your little one underneath,and then you can see the iron filings moving.<br>那么我们这儿有一些叫做铁屑的东西。你可以把磁铁，甚至是你的小磁铁放在下面，然后你可以看到铁屑在移动<br><br>Yeah, wow it stands up.Yeah, they will stand up like hair almost, very cool.<br>So now we’ll make something called goop.So we have our little bowl here and we’re gonna make our goop.<br>那么现在我们要制作一种叫做半流体的东西。所以我们这儿有小碗，我们要制作我们的半流体。</div><div><br>So the first thing we put in is our iron filings.OK just pour them all in there.And then we have some glue.<br><br>And we’re gonna take this bottle of glue，and we just put a little bit in, okay?Just a little bit there.<br>我们要把这个胶水的盖子取下来，我们只要倒入一点儿在里面，知道了吗？只要一点点。<br><br>And now, our goop is almost ready.<br>现在，我们的半流体几乎准备好了。<br><br>We’re gonna take this popsicle stick.So first you just stir the glue in with the iron filings.It’s very gooey.<br>我们要用这个冰棍棒。所以首先你只要将胶水和铁屑搅拌在一起。非常的粘哦。<br><br>Now once you have a little bit mixed.next we take some corn starch.And we’re just gonna pour the corn starch right into there.<br>现在当你稍微将他们混合起来后，接下来我们要用玉米淀粉，我们要将玉米淀粉倒入里面。<br><br>OK, now we’ve got the corn starch is mixed in with the glue and the iron filings.And then you just stir it all together, okay.<br>好的，现在我们已经将玉米淀粉和胶水还有铁屑混合起来了。然后你只要将它们都搅拌在一起，好的<br><br>It takes a little bit of time to mix everything together<br>And eventually, everything will mix together.</div><div>And if it’s too thick, put some more glue,if it’s too thin, add a little bit more corn starch.<br></div><div>如果太稠的话，就加入一些胶水.如果太稀了，就加入一点儿玉米淀粉<br></div><div>How’s that look? Oh it looks like ice cream.but don’t eat it.<br><br>Alright, now our goop is ready.So the first thing I’ll do is I’ll try your magnet, the small one.</div><div><br></div><div>And try to get the goop to move and go up a little to the magnet.Look，It’s moving a little bit, yeah.Up, up, up.</div><div><br></div><div>OK, you can see that little piece there is moving with my magnet, see?Yeah, it’s dancing!<br>好的，你们可以看到这一小块正在跟着我的磁铁移动，看到了吗？<br>And if you get too close it will go right up to the magnet.So you just keep it up a little bit and there, you see it’s coming up.<br>如果你靠的太近，他们会直接粘到磁铁上。所以你要保持一点儿距离，然后你会看到它起来了。<br></div> So you just get it where you can see the goop is moving, okay?And then you go a little closer.And the goop should start to come up to your magnet.So you just keep moving it around.and you’ll see the goop starts to come up to your magnet.But remember, don’t go too close or it will go……<div>That was pretty cool.but why does it go up, is that because of the glue?<br>It’s not because of the glue, bit a little bit because The magnet will attract the iron filings which are mixed with the glue and corn starch.<br>磁铁会吸引混合了胶水和玉米淀粉的铁屑。<br><br>Why does a magnet attract the goop?<br>The goop contains iron fillings or powder.The iron in the goop is magnetic as magnets are attracted to metal.And because the goop is a thick liquid,when we put the magnet close to it, the goop will rise upwards.<br>这个流体中含有铁屑或铁粉。磁铁可以吸引金属，流体中的铁是有磁性的。因为这个流体是浓稠的液体。所以当我们用磁铁靠近它时，流体就会向上升起。</div>
