Filtering Water
In science, we have been experimenting on filtering water using only the resource given.
Aim:
To filter dirty water into a clean and drinkable water
Equipment:
Aim:
To filter dirty water into a clean and drinkable water
Equipment:
- Plastic Cups 2x
- Empty Water Bottle
- String
- Cotton Balls
- Paper Towels
- Fabric
- Scissors
1. Cut the bottom of the water bottle leaving a big hole.
2. Turn the bottle upside down putting the top at the bottom.
3. Cut the fabric in half.
4. Stack the paper towel and cotton balls inside the bottle and alternating them.
5. Tie the fabric onto the nozzle of the bottle.
6. Put 1 cup at the bottom of the bottle. Reserve the remaining cup
7. Pour the dirty water into the bottle.
Conclusion:
How well did your design work?
My team's design worked amazingly because we made the water pretty clear on our first try.
What went well, what didn't go so well?
Our first and second try was good because the water we filtered was clear.
Why do you think it worked in a certain way?
I think our water is clear because it went through a lot of process. First it went through a paper towel, then through cotton balls, then through paper towel, then through cotton balls alternating them, then through a fabric, then through a fabric again at the end. Which I think filtered the the water making it clear.
What items were helpful?
I think that the fabric was very helpful because it prevented the dirt from getting into the water.
How did you have to modify items?
My team didn't have to modify anything because everything went well.
Here is a video on how to filter water from someone.

ReplyDeleteGreat write up on your experiment, looks really good because you included all of the topics from the handout. Very interesting how you were able to get the water so clear after a single trial. Would have been good to see you try and increase the speed of the filtration with further trials.
