The Lighthouse Lab I'm going to go ahead and put it in the middle of the middle.

Thank you.

Oh, hey there.

If you've ever taken a bath before, you'll have noticed that some things Like this rubber duck, Stay on top of the water.

They float.

Other things, like this bath plug, sink to the bottom of the bath.

They sink in water. So what causes this?

Well, the simple answer has to do with density.

Density is the amount of mass an object has in a given volume.

The more mass an object has in a given volume, the more dense it is.

Objects that are more dense than water will sink to the bottom.

But objects that are less dense than water will float on the top.

Our rubber duckies volume is mostly made up of air which is less dense than water.

That's why it floats on top.

Take a look at these objects.

Let's make predictions about which ones will float or sink when placed in this bath of water.

Thank you.

This is a ball of modelling clay.

Hmm, it feels pretty heavy.

I think it might sink.

What do you think?

Yep.

It's definitely more dense than water.

Thank you.

What about this metal coin?

Metal is pretty heavy.

I think this is definitely going to sink in water.

Yep.

Definitely more dense than water.

This polystyrene ball is very light.

I think this is definitely less dense than the water.

What do you think?

Yep.

It floats.

What about this ping pong ball?

It feels very light too.

I think it's less dense than water.

It floats.

What about this glass marble?

Hmm.

Yep, definitely more dense than the water.

This is a wooden block.

Hmm.

I'm not sure about this one.

What do you think?

Wow, it floats.

So the wooden block is less dense than water.

That was fun, wasn't it, rubber ducky?

What's that?

You want to go for another swim?

Here you go.

See you next time in the Lighthouse Lab.

Music.

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。
