Planning
Aim:
I want to find out if you can remove salt from water.
Method:
- Get a big bucket
- Full it with water and then add some salt
- Place a cup in the middle of the bucket, make sure that the cup rim is higher than the water level.
- Cover the top of the bucket with glad rap and place a rock on it, in the of the glad rap
- Put the bucket outside where it wont tip over.
- Look at it in the next morning there should be some water in the cup and salt on the bottom of the bucket.
- There might still be some drops of water on the glad rap.
Equipment:
- Water
- Salt
- A Big Bucket
- Glad Rap
- A Stone
- A Glass Cup
Brief results:
We had to leave it for a week in the bucket, the results are that we made 40mls of fresher water than before from the salty water... Next time we need multiple of bucket's with salt water and a beaker in the centre to make 2 litres of not as salty water so we can survive a day...
