Science (dirty water)

The goal of the experiment - To filter water with simple items.
equipment:   bottle, 2 plastic bottles, paper towels, string and cotton balls



(insert photo)

what we noticed- the water was still a bit murky so we are going to re filter it again till its clear.

what we changed- we loosened the rope to make the water drain faster.

What we should've done: we shouldn't  of put the cotton balls in it because it soaked up some of the murky water.

Conclusion, Our filter ended up working very well we ended up filtering all of the sand and mud but the water turned yellow.

bacteria

Bacteria constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria have a number of shapes, ranging from spheres to rods and spirals 

The food product itself supplies the food and water needed for bacterial growth. Most seafood products provide an abundance of food and water for growth. ... By controlling nutrients, water, temperature and time, air, acidity, and salt, you can eliminate, control, or reduce the rate at which bacteria grow.
