Aim:
For this term’s science, we will be doing chemistry. Our first experiment we will be starting this term is water filtration. We will be making water filters and drinking the “clean” water we’ve filtered the dirt out.

These two videos show 2 examples of ways you can make a water filter, I looked at the most simple ones I can find. And the equipment required that I can provide for myself.
Equipment:
- Plastic Bottle
- Handful of cotton
- Gravel/Pebble
- Rocks
- Sand
- Charcoal
- Scissor
- “Dirty Water”
Instruction:
- Cut your empty bottle in half.
- Place the top half of the bottle upside down onto the other half.
- Place a handful of cotton inside the bottle and push it down.
- Pour a handful of sand into the bottle, making it the second layer on top of the cotton.
- On the third layer put a handful of charcoal on top of the sand.
- Even the amount of gravel and pebbles just like the other equipment, making it the last layer.
- Pour the dirty water onto the filter, the water should come out clear at the tip of the bottle.
Results:
I do have a picture, however I’m not able to insert it through my post. I don’t know why and what’s causing my device to act like this.
Although the water filter paper was able to take out the big pieces of dirty sediments, it doesn’t fully clear out the water. It does clear out the water by 99% though.
Discussion:
What is the purpose of the rocks and pebbles? The purpose of them is to take out bigger sediments out of the water.
How do water filter papers work?
Filter papers have small pores, and this allows the small liquid molecules to pass through. This doesn’t allow the large solid particles to get in.
Why is it necessary we have clean water?
It is essential that humans drink clean water, because when we drink contaminated water and poor sanitation it leads to different types of diseases. Most of these diseases can cause immense pain and could possibly lead to death.
Is it safe to drink filtered water?
Yes it is safe, if you were to use a method like we did. Where it takes out the larger sediments and clears the water. It didn’t give me any sort of side effects. But if you didn’t know, the bacteria living in the water hasn’t fully broken down, and this bacteria called Giardia, can make you poop just water.
What is filtering? What are we separating?
Watering filtering is when we separate a solid from a liquid.
