Purifying Water

       26th Monday, February 2018
 L.O: Design and carry out an experiment.
LO2: Explain separation via filtration

Aim: 
To attempt purifying dirty water alongside, carrying out the discussed plan to construct the process.

Materials:

• Paper Towels 
• 1 Bottle
• 2 Plastic Cups
• 1 Thread Of String
• Cup Of Muddy Water
• Cotton Balls

Steps:

• We laid out our given equipment provided in ice-cream containers, Sarah began to cut out the bottom end of the bottle in order to initiate our plan.

• Since the bottle was so thick and hard to cut through with blunt scissors, we came up with an idea to bend the bottle to make a flat surface so that the scissors could break through.

• After successfully cutting the bottom half of the bottle, we began to stuff numerous of tissue papers/ cotton balls in the process of purifying the dirty water.

• After doing so, Sarah helped me tie the rope around the cloth to cover the opening where the dirty water will soak through. 

• Successfully finishing the process of purifying the dirty water, the wet substance slowly soaked through the cloth due to the dirt and tiny rocks clogging its flow. Little by little, the plastic cup was slowly being filled with more clearer water.

Edit: Refiltering the previous purified water, I noticed how the water soaked through the cloth more quickly than last time. Having no dirt or sand mixed with the water, it's flow was faster than usual.

Observation: On our third refilter, we changed the paper towels because the tiny particles of dirt hidden within the filtered water might flow within the water once poured again. The water has become a tad lighter than before.
