Overview

How does bacteria grow and spread in our everyday life? This experiment will help you think better and not touching everything you see, or washing your hands regularly before eating or doing everyday things and being careful about your hygiene.

Hypothesis

This research experiment uses Petri dishes to determine which of the five objects are dirtier—a television remote, a whiteboard, a door handle, computer keys, and a desk—and which has the most germs.

Research

We want to research why bacteria grows and spread to help people be more concerned and alert about their health. It is important to wash your hands to make sure it does not spread; for example the guy touched the very dirty television remote and rubbed his eyes and sucked his finger then the bacteria got passed his white blood cells that break down bacteria, then he gets the flu

Variables

We will be taking a photo of what the germs look like after a week, immediately right after we clean them, we will take a second photo, and a week after the cleaning, we will take one more picture and see what can change
