Hello, I'm Silvia. Today we are going to find out more about mixtures. There are two

2
00:00:07,759 --> 00:00:15,679
different mixtures heterogeneous and homogeneous but which one is which? Now I am going to do

3
00:00:15,679 --> 00:00:27,920
experiments about mixtures. We need four solids that dissolve in water. I choose sugar, salt,

4
00:00:27,920 --> 00:00:38,960
sun of Morocco and biscuits. Also you need eight transparent cups, cold water and hot water

5
00:00:39,759 --> 00:00:54,350
and a spoon to stir. First you have to put four cups in front of the solids

6
00:00:54,350 --> 00:01:18,819
Then, put water inside, like this Now, with the spoon, put a little bit inside

7
00:01:18,819 --> 00:01:57,540
Then, we are going to stir the sugar The sugar starts to dissolve

8
00:01:57,540 --> 00:02:14,020
The sugar dissolved in water Let's try with the salt

9
00:02:14,020 --> 00:02:34,879
The salt is dissolved in water, in cold water.

10
00:02:34,879 --> 00:02:40,639
The sand don't dissolve in water.

11
00:02:40,639 --> 00:02:49,099
Let's try with the biscuits.

12
00:02:49,099 --> 00:02:52,860
They don't dissolve in cold water.

13
00:02:52,860 --> 00:03:17,310
Now let's try with hot water.

14
00:03:17,310 --> 00:04:14,060
the spoon to stir let's stir the biscuits the biscuits don't stir in hot water

15
00:04:14,060 --> 00:04:41,730
Now the sand. The sand doesn't dissolve in salt water.

16
00:04:41,730 --> 00:04:56,980
Let's try with the salt. The salt dissolves in hot water.

17
00:04:56,980 --> 00:05:09,339
The sugar dissolves in salt water.

18
00:05:09,339 --> 00:05:15,339
Incredible! We've done the experiment good!

19
00:05:15,339 --> 00:05:21,029
As you have seen, there are lots of things to do at home.

20
00:05:21,029 --> 00:05:25,029
Stay at home, but no others.
