1
00:00:09,620 --> 00:00:10,940
Hey, hello everyone.
2
00:00:11,600 --> 00:00:12,380
My name is Mr.
3
00:00:12,380 --> 00:00:12,830
Yaro.
4
00:00:13,220 --> 00:00:15,770
And today we have a
very interesting topic.
5
00:00:16,400 --> 00:00:18,290
Each of you heard about chemistry.
6
00:00:18,950 --> 00:00:22,320
Sounds like something
dangerous, but actually not.
7
00:00:23,010 --> 00:00:26,760
Chemistry it's a science knowledge
about different materials.
8
00:00:27,745 --> 00:00:32,468
How to mix this materials and how exactly
this materials can behave after mixing.
9
00:00:33,038 --> 00:00:33,848
In chemistry
10
00:00:33,938 --> 00:00:35,978
it's very urgent to be precise.
11
00:00:36,608 --> 00:00:41,588
Because mixing of different proportions
can be dangerous, especially for safety.
12
00:00:42,158 --> 00:00:46,268
We can use different chemical
tools from chemical laboratory.
13
00:00:46,878 --> 00:00:53,708
And this chemical tools can help us
to deal, with uh, a various chemicals.
14
00:00:54,218 --> 00:00:55,988
So let's check this out
what do we have here.
15
00:00:56,718 --> 00:01:00,338
I want to introduce you
a simple chemical tools.
16
00:01:00,758 --> 00:01:03,578
This chemical tools you can find
in every chemical laboratory.
17
00:01:03,783 --> 00:01:09,153
So it's very urgent in chemistry
in mixing it's protects our eyes.
18
00:01:09,723 --> 00:01:13,773
For eyes protection we use safety goggles.
19
00:01:15,303 --> 00:01:19,513
Also, we want to protect our
hands - we can use safety gloves.
20
00:01:26,863 --> 00:01:27,433
Next part.
21
00:01:27,913 --> 00:01:29,533
So this is beaker.
22
00:01:30,343 --> 00:01:32,353
We can use big beaker and small beads.
23
00:01:33,288 --> 00:01:37,728
Big beaker will help us to
carry all liquid for experiment.
24
00:01:38,298 --> 00:01:40,518
The small one, you can
transfer a little bit
25
00:01:43,998 --> 00:01:47,838
and after we can do our experiments
with this amount of liquid.
26
00:01:49,788 --> 00:01:51,228
So next one - tray.
27
00:01:52,218 --> 00:01:57,198
So tray can help us to carry all
materials like small or weak.
28
00:01:57,918 --> 00:02:01,278
Next part is plastic container with leed.
29
00:02:02,378 --> 00:02:07,908
A plastic container can help to store
different materials like liquids
30
00:02:07,968 --> 00:02:13,688
or powder or even something gooey.
31
00:02:13,688 --> 00:02:13,988
Next.
32
00:02:14,498 --> 00:02:18,968
This is great cylinder,
long beaker with ruler.
33
00:02:19,418 --> 00:02:21,863
And we can see amount of liquid inside.
34
00:02:23,513 --> 00:02:25,433
Next part is a bottle with lead.
35
00:02:25,643 --> 00:02:28,343
We can store powder.
36
00:02:31,283 --> 00:02:32,783
Next is flask.
37
00:02:34,013 --> 00:02:36,323
With flask we can observe
reaction in different way.
38
00:02:39,203 --> 00:02:40,103
Here's the petri dish.
39
00:02:40,883 --> 00:02:42,703
We can observe a small reactions here.
40
00:02:44,748 --> 00:02:47,838
And by tweezers, we can
catch small materials.
41
00:02:53,038 --> 00:02:54,148
Next one is pipette.
42
00:02:54,258 --> 00:02:56,768
With pipette we can transfer
a small amount of liquid.
43
00:03:05,058 --> 00:03:05,908
This is the spoon.
44
00:03:06,098 --> 00:03:10,758
Spool we can use if we need to transfer a
small amount of powder or mixed something.
45
00:03:11,288 --> 00:03:13,788
And finally, of course,
this is the lab coat.
46
00:03:14,118 --> 00:03:16,458
The lab coat can protect our clothes.
47
00:03:17,378 --> 00:03:17,828
Okay.
48
00:03:18,178 --> 00:03:22,358
If we know how to use all of these
tools and if we know everything
49
00:03:22,358 --> 00:03:26,228
about safety, I guess we can
do a simple chemical reaction.
50
00:03:27,218 --> 00:03:33,318
So for simple chemical reaction, we will
use petri dish and is this magic powder.
51
00:03:34,628 --> 00:03:37,758
For this magic powder we will use spoon.
52
00:03:48,798 --> 00:03:49,818
Let's use this liquid.
53
00:03:50,718 --> 00:03:53,718
All right, let's count: three, two, one.
54
00:03:56,138 --> 00:03:58,778
Uh huh.
55
00:04:00,213 --> 00:04:00,783
Very good.
56
00:04:00,993 --> 00:04:03,963
So guys, as you can see, it's very
interesting reaction with bubbles.
57
00:04:04,863 --> 00:04:05,673
See you next time.
58
00:04:05,943 --> 00:04:06,423
Bye-bye.
