Filtration in science

We done a expirement trying to fillter real dirty water in to cleanish water
Method: we filled a large becker with dirty water we got a funnel and a conical flask we half filled the funnel with pebbles to fillter out the larger solids from the water then we took the pebbles from the funnel  and used the water from the conical flask and repeated the prosess again but with charcoal then we tipped out the charcoal and used the water from the conical flask again but this time we used fillter paper and a clean conical flask then the water was cleaner than what it started as but i still would not drink it cause it was still light brown it would of turned out better if we did more steps it would of be cleaner

here are two fillters for real world situations

my electro magnet

i made my own electro  magnet i found out it had to have about ten volts then i made some changes that the teacher suggested and it works with 3 volts and 1.5 volts that is a double a battery

here of some photos of it before and after

this was my test to see if hire voltages made the strength more powerful

0.5volt 110 paper clips

1 volt 7 paper clips or 27 paper clips

1 volt 110 paper clips

turns out it was not more powerful the hire the voltage

1 volt was the same strength as 10 volts

After

 

the Most powerful electro magnet ?

the most powerful electro magnet was a nikola tesla idea it was Wardenclyffe Tower his idea failed but at the same time the idea he made it for happened he said someday people will be able to talk to people on the other side of the world 

poem

this is my poem
Super relaxing out on the water
A extraordinary sport to do
I love the Adrenalin
Leg workout when you are hiking out
Inexpensive  sport at the waimak
Nothing else like it
Going with the wind and the boat
