Background Information/Research

Conclusion

Hypothesis

The Problem/Purpose

• 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

• 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

• 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

• 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.

Step by Step Procedure

Materials

Now I am going to show you how I Make an Egg Float in Salt Water

Acknowledgments

First through Fifth Steps

This is an video of how to make an egg float in salt water enjoy!

I poured about 3 cups but it depends on how big your glass is.

Insert your egg very gently.

I added about 2 tbsp but again it depends on how big the glass is.

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

Thank you we R

Measure every 2 tbsp.

Each column is about how much the egg floated every 2 tbsp

4.

4x

Repeat Steps 4 and 5, four times

Forever!

Thank You For Your Attention!!

Vocabulary

Any Questions?

• There are a few words you may of not known

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.

Density-the degree of compactness of a substance Example- thickness, solidity, mushy

Dependent- requiring someone or something for financial or other support Example-relying on, counting on, support

Pressure- continuous physical force exerted on or against an object by something in contact with it Example- load, trust

Salinity- the taste experience when common salt is taken into the mouth Example- brininess, saltiness

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

Skewer- a long piece of wood or metal used for holding pieces of food, typically meat, together during cooking Example- rod, bolt

• Precisely-in exact terms without vagueness Example- sharp, exactly
