Waterless Urinals: A Science Project

Hard
Waterless Urinals: A Science Project | Science Fair Projects | STEM Projects
Are waterless urinals really more hygienic than water-based urinals? Let's find out by comparing the amount of bacteria growth in petri dishes from samples collected from both types of urinals.

Hypothesis

The hypothesis is that waterless urinals will have less bacteria compared to the water-based urinals.

Method & Materials

You will collect bacteria samples from waterless and water-based urinals, measure the amount of bacteria growth in petri dishes, and compare the results.
You will need petri dishes, disinfected swabs, sterilized water, latex gloves, and a marker pen.

Results

The results show that petri dishes from waterless urinals have a smaller amount of bacterial growth compared to petri dishes from water-based urinals. This proves that waterless urinals are more hygienic than water-based urinals.

Why do this project?

This science project is interesting because it explores the differences between two types of urinals and helps us understand which one is more hygienic.

Also Consider

Experiment variations include collecting bacteria samples from other areas around the urinals such as from the floor, walls or wash basins near the urinals, and collecting swab samples from at least 5 different spots/locations within each urinal.
