HOW DOES MOTOR OIL AFFECT A PLANT?By Jennifer Zhu
BACKGROUND RESEARCH BP Oil Spill
4 million barrels of petroleum leaked into the oceanDrilling rig exploded in the Mexican Gulf
Burned petroleum gives out emissions of sulfur dioxide, carbon monoxide, nitrogen oxide, and particulate matter
Sulfur Dioxide causes acid rain, a harmful chemical to plants and animals who live in the water
Nitrogen oxide contributes to ground level ozone, and can lead to an irritation and damage of the lungs
Particulate matter can lead to asthma and chronic bronchitis in children
Carbon Dioxide is a greenhouse gas responsible for global warming
BACKGROUND
Petroleum contains hydrocarbons, molecules made up entirely of hydrogen and carbon
Contains Sulfur, and can be classified as sour and sweet due to the amount of sulfur.
Conventional motor oil is petroleum oil pumped up from the ground-will be used in the experiment
BP oil spill leads to scientists discovering new ways to “cure plants” which had been effected by petroleum
What exactly does petroleum do to a plant?
PROBLEM + HYPOTHESIS
Does the amount of petroleum affect a plant’s height over time?
If the amount of petroleum is greater, then the plants will lose height quicker.
MATERIALS + IV, DVMaterials for the
experiment:o Pencilo Papero Coffee Plants (9)o Watero Sunlighto Motor Oilo Dropper
o The IV: The amount of motor oil put in
o The DV: The plant’s height after being infected with motor oil
o Time Span: 3 weeks
SETTING UPStep 1• Gather Materials
Step 2• Separate plants into 3 groups: Control, testing two drops, testing 3
drops
Step 3• Label plants 1A, 1B, 1C, 2A 2B, …etc.
Step 4• Measure original height
Step 5• Water plants
Step 6• Give Plants 2 days to adjust to different temperatures
PROCEDURE
Step 1:Take Measurements
Step 2:Fill dropper with oil
Step 3:Drop 2 dropsOnto plant 2A
Step 4: Repeat step 3 with
plants 2B&2C
Step 5:Fill dropper with Oil
Step 6: Drop four drops onto plant 3A
Step 7: Repeat step 6 with
plants 3B&3C
Step 8: Water all plants
Step 8:Wait 1 Day
Repeat whole process

Plants 2A, 2B, 2C: Two drops added
Plants 3A, 3B, 3C: Four drops Added
