Background Research

[Amanda Dotterer]

Hi, I am an 8th grader at Hereford Middle School in Northern Maryland. I
need help getting background research for a science experiment. Here is my
problem question: What is the effect of different liquids (watering the
plant with bleach, water, etc.) on plant height? I have heard that watering
a plant with bleach will make the leaves and stem (and soil) turn white. I
was wondering if you could provide me with a little background information
on this subject so I can start my project. My e-mail address is
miazr007@..., so you can e-mail me back.

Thank You!

Amanda

There are many answers about student projects on watering plants with
different liquids at MadSci.org. Most liquids other than water will be
harmful to most plants, including bleach, milk, sugared sodas, and
fruit juices. Some liquids may not be too harmful to plants, or
slightly beneficial, such as diet soda, coffee and tea. Plant growth
may also be affected by different types of water (tap water, softened
water, distilled water).

The optimal irrigation solution for plant growth is usually good
quality tap water or a dilute fertilizer solution.

Bleach is a solution of sodium hypochlorite (NaOCl). Search the
internet for a Material Safety Data Sheet on sodium hypochlorite to
find some basic information. Sodium in high concentrations is toxic to
most plants. There is a lot information on the effects of table salt
(sodium chloride) on plants. Search for plant salinity.
