The document describes two experiments conducted to understand water usage and filtration. The first experiment measured that 27ml of water is lost if a tap is left running for 5 minutes. The second experiment showed that not all water is filtered through soil and some remains in the ground. The conclusion is that water should be saved to avoid wastage from dripping taps and because not all water cycles back to be reused.

3. EXPERIMENTATON 1
• In this experiment have acute (using suitable
material) to calculate how many ml went
down in five minutes.

4. CONCLUSIONS TO EXPERIMENTATION 1
We discovered that if a family leave the tap running for 5 minutes loses 27
ml of water.

5. EXPERIMENTATON 2
• in this experiment have been filtered (using
suitable material )water among soil types.

6. CONCLUTIONS OF EXPERIMENT 2
•
IN THIS EXPERIMENT we found that not all water is filtered but there IS THAT IN THE
LAND

7. CONCLUTIONS
•
I save could be for many reasons such as:
•
There are families who leave taps dripping and it has qiue avoid
•
it may also be that the water stays in the ground and we can not take.
