1
00:00:02,029 --> 00:00:21,620
Experimental!

2
00:00:21,620 --> 00:00:31,339
If some solids are soluble or insoluble.

3
00:00:31,339 --> 00:00:34,340
First, we make an hypothesis.

4
00:00:34,340 --> 00:00:37,340
And then we do the experiment.

5
00:00:37,340 --> 00:00:40,340
To do this, we need to choose four solids.

6
00:00:40,340 --> 00:00:42,340
We chose...

7
00:00:42,340 --> 00:00:44,340
two of them.

8
00:00:44,340 --> 00:00:46,340
Instant coffee.

9
00:00:46,340 --> 00:00:49,340
Sands

10
00:00:49,340 --> 00:00:51,340
And cookies

11
00:00:51,340 --> 00:00:53,340
We also need

12
00:00:53,340 --> 00:00:56,340
Plastic plastic

13
00:00:56,340 --> 00:00:58,340
Cold water

14
00:00:58,340 --> 00:01:01,340
One spoon

15
00:01:01,340 --> 00:01:17,390
Hot water

16
00:01:17,390 --> 00:01:21,390
First we add sugar to cold water

17
00:01:21,390 --> 00:01:28,959
Then we add instant coffee to cold water

18
00:01:28,959 --> 00:01:35,459
After that, we add sand to cold water.

19
00:01:36,459 --> 00:01:41,459
And finally, we add the cookies to cold water.

20
00:01:58,909 --> 00:02:01,909
Now we repeat the same process.

21
00:02:01,909 --> 00:02:03,909
But with hot water!

22
00:02:26,439 --> 00:02:54,629
We found out that because we can see the sun.

23
00:02:55,629 --> 00:02:55,870
Thank you.
