How Do Arsenic Levels In Soil Affect the
Growth of English Ivy?
Our project: By Lotos Chen
have been told to research about the arsenic levels in Sweet Home, Oregon.
My group and I have decided that our goal is to research and experiment
about the relationship between arsenic levels in the soil and the growth of
plants. In other words, we want to
find out if the arsenic levels in the soil affect the growth of plants.
The plant that my group and I have chosen to experiment with is English
Ivy. English Ivy is also known as Hedera helix, it is an evergreen
climbing vine that belongs in the ginseng family. English Ivy is a very aggressive plant that invades the space
of many plants both on ground and in the air.
Most of the time this ivy kills plants, for example trees. (Swearingen and Diedrich, 2000) We chose to use the
plant, English Ivy because we thought that it would grow more effectively and
relatively faster then most other plants. Thus
we decided that it would be the best choice for our experiments.
We plan to monitor the growth of the English Ivy seeds as much as
possible to determine whether or not arsenic in the soil prevents or slows down
the growth of plants. To monitor
the growth of the English Ivy we are going to measure them by their stems with a

In order to find out if arsenic levels in the soil affect the plant
growth, our plant is English Ivy. We
retrieved soil samples from Crescent Valley High School, Corvallis Oregon and
Sweet Home Oregon. First Sweet Home
Oregon we collected the soil samples. The
Soil samples were four-six inches deep the seventh inch was the soil that we
gathered (Jim Childs 1999).
We found the exact position with a GPS so this can be duplicated.
Then after the soil had been collected we put the soil evenly into eight
jars, filled to 6 inches uncompressed. Then
label each jar S1, S2 ext. up to eight. Then
put the soil in a box so when you put the lids on the jars they donít get any
sun, like what we did. Store the
samples in a room at a normal room temp. Repeat
this procedure at Crescent Valley High School Corvallis Oregon the next day.
After the samples were collected and stored in the same spot, then you
take the jars and pore the entire contents into the sixteen pots labeling each.
Then take the English Ivy sprouts and plant one in each pot.
Place the pots in an outside room with ventilation to the outdoors and a
sunroof. Then analyze the growth
every Friday. The way we are analyzing is by measuring the growth and comparing
the plants too each other. Water
them with the same amount of water (about 50ml) every other day from the first
day on. While you are doing this also send a sample down to the OSU reactor to
have it analyzed.
