Floating Eggs In Water

INTRODUCTION

Eggs are known to sink in water. In this experiment, we will be able to let the eggs to float in water. In this simple scientific study, we will be able to know the contributing factors that allow eggs to float in water.

PROBLEM

How to let eggs float in water?

HYPOTHESIS

Since saltwater has the capacity to make things buoyant, it is assumed that kitchen salt will make the eggs float.

MATERIALS NEEDED

One egg

Water

Salt

A Drinking Glass 

PROCEDURE

Pour water into the glass until it is about half full.

Stir in lots of salt (about 6 tablespoons).

Carefully pour in plain water until the glass is nearly full (be careful to not disturb or mix the salty water with the plain water).

Gently lower the egg into the water and watch what happens.

RESULTS / ANALYSIS OF DATA

Results show that as you add salt in the drinking glass, eggs will eventually float higher. The hypothesis somehow matched the results. The density of the water enables the egg to float in.

CONCLUSION

It is therefore concluded that salt allows eggs to float in because of its density. It is the same as the principle of the boat that floats in the ocean.
