Better Late Than Never! EGGsperiment Results


After a much needed technology break, I’m back!  Just before Spring Break, we participated in an EGGsperiment EGGstravaganza.  Students completed 5 experiments using eggs in many different forms.  For each experiment they were given the materials and procedure but had to create a hypothesis and then record observations in their lab report.  We had an awesome day!  Below are the experiments and instructions.  Thank you to the many teachers who post to Pinterest!  I unfortunately can not take complete credit for developing the experiments on my own, only for implementing them in my class.

EGGsperiment #1- The Bouncing Egg

For this experiment 2 eggs were used.  One was raw, the other was hard boiled.  Both eggs spent 48 hours soaking in vinegar to strip them of their outer shells.  Once stripped, students created a hypothesis as to how high off the table we could hold the egg and drop it without it breaking.  Most students guess between 3-5 inches.  Our raw egg made it to 9 inches and our hard boiled one never did bust!


EGGsperiment #2- Humpty Dumpty

Students were given raw eggs for this one.  They had to hypothesize the outcome of the egg falling off our “wall” onto cotton balls, paper, and the desk.  Most Humpties made it up until the desk trial.


EGGsperiment #3- The Volcanic Egg

For this experiment, students were given hard boiled eggs to paint with a paste of baking soda and food coloring.  Once painted they had to hypothesize what would happen when they dropped the egg into a cup of vinegar.  Things got quite colorfully messy!


EGGsperiment #4- The Incredible Shrinking Egg

Students were given 2 naked eggs (raw eggs that had been soaked in vinegar for 48 hours to remove outer shell).  One egg spent 24 hours naked in water.  The other egg spent 24 hours naked in a water/sugar solution.  They had to hypothesize what would happen when they pierced each of the eggs with a thumb tack.  The Sugar egg was much weaker and exploded, while the water egg only let out a fountain stream of water.

EGGsperiment #5- The Strong Egg

This experiment was two-fold.  The first part had students test their strength vs. that of an egg.  Could they crush an egg in one hand?  In most cases that answer was no!  

The second part of the experiment was to place 2 eggs under a stack of books and hypothesize how many would be needed to crush them.  Surprisingly, the answer was many more than most students predicted, but in the end all eggs were eventually smashed!
