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.

Procedures

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

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

Day 2 Water

• Today we put the egg in 200ml of water. The egg
  was bigger and the shell dissolved.

Day 2 Mass Circumference
64g 16.6cm

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

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

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

Day 6

• At the end the egg got smaller and weighed more.

Day 4 Mass Circumference
76g 15.5cm

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.
