In part two of the egg lab we placed the de-shelled eggs in salt water. Most students discovered that the salt water made their eggs swell. Some increased their size by six centimeters!
In part three, students placed their eggs in a solution of their own choosing. Most used some kind of colored water. A few combined that with hand soap or Big K soda. One used a mixture of vegetable oil and baking soda.
We will be finishing the egg lab shortly and students will make a graph that shows how their egg was affected by the solutions they used.
