2. My Question
How will my egg change based on the liquid it is in?

3. My Hypothesis
In vinegar the egg will shrink.In the water it will absorb the water.But in the saltwater it will shrink again.With the food coloring the egg will change color.Next we put it in soap and the egg would get a little bit bigger.

4. Procedures Find the mass of egg using a scale
Find the circumference of the egg using a string and then a ruler
Write down observations of egg in data table
Using a graduated cylinder, measure 200ml of vinegar and add to container
Carefully add egg to container and leave for 24 hours
Repeat steps 1-5 but with saltwater, then food coloring, then a liquid of choice

5. Day 1 Vinegar
Today we put the egg in 200ml of vinegar. The egg was smooth,white and has a hard shell.
Day 1
Mass
Circumference
54g
14cm

6. Day 2 Water
Today we put the egg in 200ml of water. The egg was bigger and the shell dissolved.
Day 2

64g
16.6cm

7. Day 3 Saltwater
Today we put the egg in 200ml of saltwater. The egg got smaller and weighed more.
Day 3
Mass
Circumference
16.6cm

8. Day 4 Food coloring
Today we put the egg in 200ml of food coloring. The egg got smaller , weighed more and changed color.
Day 4
Mass
Circumference
84g
16.2cm

9. Day 5 Soap
Today we put the egg in 200ml of soap. The egg got smaller , weighed more and stayed same color.
Day 4
Mass
Circumference
74g
15.5cm

10. Day 6 At the end the egg got smaller and weighed more. Day 4 Mass
Circumference
76g
15.5cm

11. My Data

12. Conclusion
We were correct in vinegar, food coloring, and soap.But we were wrong in the water and saltwater.For the water and saltwater the egg got bigger and softer. In the vinegar, food coloring, and soap the egg shrunk and weighed more.Next time we will think more scientifically and we will think if the egg will like the different liquids.
