Layering materials must include coarse gravel, fine sand, and activated charcoal to replicate municipal treatment stages. Subsequently, add the coarse gravel layer to capture heavy sediments and provide structural support for the sand above.

Documenting Scientific Results Data collection is the cornerstone of any science project, providing evidence for the hypothesis. Follow this with the activated charcoal, which acts as the primary chemical barrier against organic pollutants.
Slowly pour this turbid liquid into the top of the filter, allowing gravity to pull the fluid through the media layers. Record visual observations regarding cloudiness and color removal at each stage.
