# Make an Egg Float in Salt Water

This is a swell project that is all about density. It is cool and everyone that looks on here should try it! You can look on a cool website called www.sciencekids.co.nz ! So get up and please try it! :)

#### Transcript of Make an Egg Float in Salt Water

Materials
Most objects float in salt water but not in fresh water because the density is higher in salt water than in fresh water.
My hypothesis of the egg was going to float in salt water because there is more density in the salt water than clean water was correct.
The problem I had was I couldn't find 3 glasses so I changed and used one
A change I would make is use other objects besides eggs that have liquid in them like us, like oranges.
My background information stated that salt water has a higher density than fresh

clean water
Fresh water has precisely 999.728 kg per cubic meter
Salt water has precisely 1026.978 kg per cubic meter
Density is dependent on salinity, temperature, and pressure
Step by Step Procedure
I would like to specially thank my mom

I would like to thank my dad

I would like to thank Science For Kids

I would like to thank Hailey

I would like to thank Ketziyah
Now I am going to show you how I Make an Egg Float in Salt Water
Hypothesis
My hypothesis stated that I thought that the egg will float in salt water because there is more density in salt water than in clean fresh water

The Problem/Purpose
By Tailan Hickey
1. Pour 3 cups of water into the glass
2. Gently put an egg in the glass
3. Take egg out, add about 2 tbsp of salt in your glass,and mix until salt completely dissolved
4. Put egg back in water, and measure to see if the egg has floated
5. Repeat steps 3 and 4, four times

The purpose of my experiment was to find out why it seemed like I float at the beach
But it seemed like I sink at the pool

Vocabulary
There may have been a few words you didn't know I will tell you what they mean now
Density- closely compacted in substance
Example- heavy, thick, or mushy
Precisely-in exact terms without vagueness
Example- sharp, exactly
Dependent-requiring someone or something for financial, emotional, or other support
Example- reliant on, relying on, counting on;
Salinity-the taste experience when common salt is taken into the mouth
Example- salt
Pressure-the continuous physical force exerted on or against an object by something in contact with it
Temperature-the degree or intensity of heat present in a substance or object, especially as expressed according to a comparative scale and shown by a thermometer or perceived by touch
Example-climate, degrees
Results: Chart of how much the egg floated
The egg was measured in half centimeters
I added 8 tbsp of salt into the glass in all
The graph shows how much the egg floated every 2 tbsp.
Any Questions?
I poured about 3 cups but it depends on how big your glass is.
I added about 2 tbsp but again it depends on how big the glass is.
Measure every 2 tbsp.
Repeat Steps 4 and 5, four times
4x
