1
♩♩Intro♩♩ Squeaks has been asking when we're going to make slime for a really long time now.
2
And so have lots of our viewers!
3
Well, guess what, Squeaks?
4
Today's the day!
5
It’s gonna be squishy, and smooth, and…probably pretty slimy.
6
And you can make it with a few simple ingredients that you probably already have at home!
7
First, you'll need a bowl, a measuring spoon, a stick or plastic spoon for mixing, a container if you want to store your slime when you're done, and a grown-up to help.
8
Our slime is going to be made out of regular school glue, baking soda, food coloring, and contact solution.
9
The contact solution should have something called boric acid in it, which a lot of them do — you can ask a grown-up to help you make sure.
10
All the ingredients we're using are safe to touch — that's the whole point of slime!
11
But it's not for eating.
12
Now for the fun part: let’s start making some slime!
13
First, pour the glue into the bowl.
14
And I bet you can guess what it’s for!
15
That's right!
16
To make it sticky.
17
But maybe not in the way you're expecting.
18
Glue is sticky, but it's still very liquidy.
19
To make slime, we need to make the glue stick to itself so it becomes a big ball of goop we can pull apart and squeeze together.
20
That's what the other ingredients are for!
21
Well, except the food coloring.
22
That's just to make the slime a cool color.
23
So the next thing we're going to do is add one tablespoon of baking soda to the glue.
24
We’ll mix the baking soda and the glue together until it's completely dissolved.
25
Then, we’ll add a few drops of food coloring and mix it together.
26
Keep adding food coloring until you make the color you want!
27
We're using fushcia.
28
Hmmm. I know it's the right /color/, but does this look like finished slime to you, Squeaks?
29
Naw, it still looks too liquidy.
30
What do you think will happen when we add the contact solution?
31
Let's see. I’m going to start adding the contact solution one teaspoon at a time so we can really observe what’s happening.
32
Oh wow! It’s really starting to get more goopy!
33
I’m going to add another teaspoon and keep stirring.
34
It looks like the slime is getting even thicker and stickier now.
35
It’s even sticking to itself!
36
That’s because of the way the baking soda and contact solution we added are changing the glue.
37
The little tiny pieces, or molecules, that make up glue are too small for us to see.
38
But if you could, you'd see that they're a lot like tiny chains.
39
At first, the glue was very runny because the chains were all sliding around each other.
40
But the baking soda and contact solution made the chains get all tangled up!
41
That's why the mixture sticks to itself and becomes more like a ball of slime.
42
Once the slime is sticking to itself more than the bowl, you’ll know it’s almost ready!
43
If your slime is still runny, keep slowly adding a little more contact solution to the glue and baking soda mixture.
44
Finally, to get your slime to the perfect level of sliminess, you’ll have to knead it with your hands, either in the bowl or on a surface that's easy to clean.
45
Keep kneading and stretching and even squishing it together until it’s the perfect slime consistency!
46
This slime is so cool!
47
I can form it into a ball and it’s almost solid, but I can also pull it apart and let it drip down.
48
It’s almost like the slime is like a solid and a liquid at the same time!
49
And that's what makes slime so special.
50
Most types of liquids only turn solid when they freeze, like when water freezes into ice.
51
And most types of solids only turn liquid when they melt!
52
But slime is different.
53
When you just leave it alone, it spreads out in the bowl like a liquid.
54
Even though the little chains in the slime are connected to each other, they can still slide around each other enough to flow like a liquid.
55
But when you press it together or pull it apart, the chains get more tangled, and the slime becomes much more like a solid!
56
Just like the oobleck we made one time, remember, Squeaks?
57
Yeah!
58
Keep playing around with your slime to see what else you can discover about it!
59
When you’re done, you can put it away in a container so it doesn’t dry out, and just make sure to wash your hands when you're done.
60
But most important of all: have fun!
61
Did you make this slime?
62
What did you learn about it?
63
Ask a grown-up to help you leave a comment below, or send us an email at [email protected].
64
We’ll see you next time here at the Fort!

推薦影片

為什麼要通過這個影片練習口語?

在這個科學實驗的影片中,主持人通過有趣的方式展示瞭如何製作史萊姆。這個過程不僅激發了孩子們的創造力,也為學習英語提供了良好的口語練習環境。在觀看影片時,學習者可以模仿主持人的發音和表達,增強自己的英語口語能力。通過這種英語影子跟讀(shadow speak)的方法,學習者不僅能提高口語流利度,也能加深對英語詞彙和句式的理解。

語法與表達的背景

影片中使用了很多有用的表達和結構,以下是幾個關鍵點:

  • 用詞的清晰性:主持人在描述製作史萊姆所需的材料時,使用了簡單而明確的詞彙,如“碗”、“膠水”和“食用色素”。這種清晰性有助於學習者理解基本詞彙。
  • 命令句:例如“先倒入膠水”,這種指令性語言適合在我們日常交流中使用。模仿這些句子可以幫助學習者在實際對話中更自信地表達自己。
  • 時態的應用:影片中常使用現在進行時來描述製作過程,如“I’m going to add…”。這種用法適合正在進行的活動,促使學習者學習何時使用不同的時態。

常見的發音陷阱

在這個影片中,一些單詞的發音可能對學習者構成挑戰:

  • “slime”(史萊姆)- 注意這個詞中的“sl”聲母,確保發音流暢。
  • “baking soda” (小蘇打)- 尤其是“soda”部分,要注意發音清晰,以免與其他類似詞混淆。
  • “contact solution” (隱形眼鏡溶液)- 這個短語中有多個音節,學習者應注意連讀,以提高口語自然度。

通過在觀看這個影片的同時,利用shadowing site提供的技術,學習者能夠更好地掌握這些發音和表達,提升他們的英語口語練習(shadow speech)能力。

影片中的語法

說話人最常用的結構,並附上影片中的原話:

結構影片中的用法
被動語態 be + 過去分詞 — 強調發生了什麼,而不是誰做的be made · are connected
動詞 + -ing enjoy、keep、stop… + -ing — 後接 -ing 形式的動詞start making · Keep adding · start adding
“will” 表將來 will + 動詞 — 決定、承諾或預測you'll need · We'll mix · we'll add
現在進行時 am/is/are + -ing — 此刻或近期正在發生的事we're using · you're expecting · is getting

什麼是跟讀法?

跟讀法 (Shadowing) 是一種有科學依據的語言學習技巧,最初開發用於專業口譯員的培訓,並由多語言者Alexander Arguelles博士普及。這個方法簡單而強大:您在聽英語母語原聲的同時立即大聲重複——就像是一個延遲1-2秒緊跟說話者的影子。與被動聽力或語法練習不同,跟讀法強迫您的大腦和口腔肌肉同時處理並模模擬實的講話模式。研究表明它能顯著提高發音準確性,語調,節奏,連讀,聽力理解和口語流利度——使其成為雅思口語備考和真實英語交流最有效的方法之一。
