EXPERIMENT 1
Make clean water from a dirty concoction
Explanation:
The water is cleaned as it passes through the filters. Just like a large
wastewater treatment plant, your equipment has several cleaning
stages. The little rocks filter out large impurities, while the sand and
paper filter hold back finer materials.
How can filthy water be made clean again?
You will need:
water-filter column, small measuring cup, spatula,
as well as: teaspoon, dirt, water (not included)
2
Pour the dirty water into the top cup
of the filter column.
3
The water that comes out the other end is a lot
cleaner than the brown broth that you poured in.
Take a look at the three filter layers!
What do you see? Write down your observations.
1
Prepare some dirty water. In the small cup,
mix water and one teaspoon of dirt.
Stir vigorously.
