Eggs & Plants
By Darren White & Jerry Camacho
Can eggshells aid in the growth of
plants?
Notes that were researched about eggshells
• An egg’s outer shell is made up of vitamins
including Calcium AND Vitamin D
• Calcium is especially important for fast growing plants
because they quickly deplete the surrounding soil of
calacium.
Vitamin D + Calcium =
Hypothesis
If eggshells are added to plant soil then it will grow
faster

Materials
1. Eggshells from the same egg
2. Plant pot (2.)
3. Bag of soil
4. Pre-mature plant (same) (2)
5. Water
Procedure
1.Place plant in two separate pots
2.Add the soil to both pots
3.Add eggshells to the soil of one plant (this
will be your experimental group)
4.Add the same amount of water to each plant
once a day over a period of 10 days
Once the experiment was under way, the variables of the experiment
were now used:
Independent Variable: Eggshells
Dependent Variable: Plant growth
Control Group: Plant with no shells given to
Experimental Group: Plants with eggshells added to its soil

Conclusion
As a result, the hypothesis stating that adding eggshells to a
plant will make it grow faster and taller was correct. Explained
by the data chart everyday the plant in the experimental group
either grew taller or stayed the same height as the control
group, never below. In order to improve this experiment, I
would used water boiled in eggs as a experimental group and
boiled water as a control. I believe that if eggshells are used to
grow plants or flowers they will grow both taller and faster.
