Hey, hello everyone.

My name is Mr.

Yaro.

And today we have a very interesting topic.

Each of you heard about chemistry.

Sounds like something dangerous, but actually not.

Chemistry it's a science knowledge about different materials.

How to mix this materials and how exactly this materials can behave after mixing.

In chemistry

it's very urgent to be precise.

Because mixing of different proportions can be dangerous, especially for safety.

We can use different chemical tools from chemical laboratory.

And this chemical tools can help us to deal, with uh, a various chemicals.

So let's check this out what do we have here.

I want to introduce you a simple chemical tools.

This chemical tools you can find in every chemical laboratory.

So it's very urgent in chemistry in mixing it's protects our eyes.

For eyes protection we use safety goggles.

Also, we want to protect our hands - we can use safety gloves.

Next part.

So this is beaker.

We can use big beaker and small beads.

Big beaker will help us to carry all liquid for experiment.

The small one, you can transfer a little bit

and after we can do our experiments with this amount of liquid.

So next one - tray.

So tray can help us to carry all materials like small or weak.

Next part is plastic container with leed.

A plastic container can help to store different materials like liquids

or powder or even something gooey.

Next.

This is great cylinder, long beaker with ruler.

And we can see amount of liquid inside.

Next part is a bottle with lead.

We can store powder.

Next is flask.

With flask we can observe reaction in different way.

Here's the petri dish.

We can observe a small reactions here.

And by tweezers, we can catch small materials.

Next one is pipette.

With pipette we can transfer a small amount of liquid.

This is the spoon.

Spool we can use if we need to transfer a small amount of powder or mixed something.

And finally, of course, this is the lab coat.

The lab coat can protect our clothes.

Okay.

If we know how to use all of these tools and if we know everything

about safety, I guess we can do a simple chemical reaction.

So for simple chemical reaction, we will use petri dish and is this magic powder.

For this magic powder we will use spoon.

Let's use this liquid.

All right, let's count: three, two, one.

Uh huh.

Very good.

So guys, as you can see, it's very interesting reaction with bubbles.

See you next time.

Bye-bye.
