00:00:01,260 --> 00:00:10,880
Good morning! We are 4th grade ESB and this school year we have studied about how to take care of the ecosystem and the earth in general.

2
00:00:11,300 --> 00:00:16,260
We realized that there is a problem at this school and we can solve it easily.

3
00:00:18,440 --> 00:00:25,260
We saw that we wasted a lot of water and energy during the break time every day.

4
00:00:25,260 --> 00:00:35,899
So we started to check all classrooms for almost three weeks to see who had left the lights, the digital boards and the taps on.

5
00:00:36,659 --> 00:00:38,219
Here we have the results.

6
00:00:40,240 --> 00:00:48,179
Regarding the water, every single day, except one, there were from one to five taps on.

7
00:00:48,659 --> 00:00:52,380
And the flow in some cases was pretty strong.

8
00:00:52,380 --> 00:01:01,640
So we waste around 150 liters of water at break when we leave the taps running with strong flow.

9
00:01:02,119 --> 00:01:08,519
And taking into account that we need 50 liters when we take a short shower around 5 minutes,

10
00:01:08,799 --> 00:01:12,200
we could have 3 showers with the water wasted.

11
00:01:12,640 --> 00:01:12,959
Wow!

12
00:01:14,680 --> 00:01:27,560
The next part of our investigation was related to the light.

13
00:01:27,560 --> 00:01:33,359
First, we asked Jesús what type of light bulbs we have at school.

14
00:01:34,680 --> 00:01:45,019
As you know, there are different kinds of light bulbs and luckily we have the ones that use less amount of energy to work.

15
00:01:45,459 --> 00:01:45,879
Great!

16
00:01:46,719 --> 00:01:54,879
Secondly, we checked if the lights were turned off in all the classrooms when they were empty at break.

17
00:01:54,879 --> 00:01:59,180
We found that the ground floor was the best.

18
00:01:59,719 --> 00:02:06,879
Infant education classrooms, they were really good at turning off the lights.

19
00:02:08,000 --> 00:02:12,259
The youngest students in the school are leading by example.

20
00:02:13,120 --> 00:02:14,080
Good job, Kinder!

21
00:02:14,780 --> 00:02:25,969
On the other hand, we found that the second floor was the worst, from third to sixth grade classroom.

22
00:02:25,969 --> 00:02:30,969
There was only one single day that no one left the lights on.

23
00:02:30,969 --> 00:02:35,969
As the oldest students in the school, we need to do better.

24
00:02:35,969 --> 00:02:38,969
As you can see, we have a problem.

25
00:02:38,969 --> 00:02:43,969
But luckily, we have some solutions to help.

26
00:02:43,969 --> 00:02:52,430
First, we made a wrap from every bullet and closed the text properly.

27
00:02:52,430 --> 00:03:02,430
Next, we wrote a fun story to explain why it's important to save water and energy.

28
00:03:02,430 --> 00:03:11,430
We also invented games for kinders, first, second and third grade to play at break time.

29
00:03:11,430 --> 00:03:15,430
This way they can learn while also having fun.

30
00:03:15,430 --> 00:03:21,430
Last but not least, we designed posters and put them in the bathrooms.

31
00:03:21,430 --> 00:03:42,030
We hope you learned something from this video and remember, you have to switch off the lights
