How do oil spills affect aquatic plants?

Topic Information :  Effects of oil spills  This science fair project was performed to find out how oil spills will affect aquatic plants. Testing was done using hydrilla plants in water with and without a layer of oil covering the surface. Oil is an organic fluid that has a lower density than water. When oil is spilled on water, it will float on the water surface and form a thin layer. Oil is not soluble in water. This thin layer of oil on the water surface is called sheen and it can kill the aquatic animals and plants that live beneath the water if it is not removed quickly. The presence of oil on the water surface will blocks sunlight and prevents air from reaching the plants that live in the water. This will prevent the plants from producing food through photosynthesis. Without photosynthesis, the plants will not be able to grow, germinate and produce oxygen. If this condition persists, the plants will eventually die. Aquatic animals are also not spared ...

Unleash the Power of the Pinwheel

Objectives/Goals The objective is to determine if the orientation to the wind affects the amount of power generated by a wind turbine. Methods/Materials A wind turbine was constructed using an empty oatmeal canister weighted with heavy bolts to keep it grounded, a wooden skewer, a homemade rotor, two feet of thread, one end secured to the aft shaft and the other to five #1 size paper clips. Using a hair drier, wind was directed toward the rotor at the following angles; 0 deg., 45 deg., 90 deg., 135 deg., and 180 deg. The time to raise the load of paper clips to the base of the shaft was calculated in seconds, using a stopwatch, and the distance the paper clips were raised at each position was measured in inches, using a tape measure, but then converted into meters. After conducting three trials, times and distances were averaged to determine which orientaion to the wind source created the most power. Results After testing all five angles three times, I#ve found ...

Fooling Your Brain with a Mirror

Aim: To prove that what we see is often affected by what we expect to see with the help of the mirror image experiment. Materials required: 1. Mirrors – 2 in number, square in shape, 12 inches (30 cm) a side, could be either made out of plastic or glass. 2. Epoxy glue and duct tapes. 3. Wooden dowels – 2 in number with diameter as 1 inch (2.5 cm) and 12 inches (30 cm) long. Procedure: 1.      Stick the mirrors together by pasting their backs. If you have a glass mirror then for safety, tape their edges using the duct tapes to seal the sharp edges. Take the two wooden dowels and paste them right in the centre of the mirrors vertically. 2.      Hold the dowels with each hand and as you look at one side of the mirror move the hand which is on the other side. What do you actually see? What happens? Your brain expects the image in the mirror to move as it is fooled to believe that the image it sees is actually your othe...

The Mathematics of Sympathetic Vibrations

Objectives/Goals  Which notes on a piano can induce sympathetic vibrations on an open string? Mathematical relationships between test note and open string frequencies will be used to predict which notes cause sympathetic vibrations. I predict the three test notes in my sample that are harmonics of the open string will resonate the longest. Methods/Materials  Materials used were: a piano, a stopwatch, a frequency chart, and a helper. I depressed a piano key, the damper lifted and the string was "open," or free to vibrate. I played all the notes in one octave higher than the open string. My helper timed the durations of the tone coming from the open string. I averaged and graphed the results.  Results  The thirteen test keys in each sample caused the open string to resonate. Seven test keys caused brief resonance; the vibration inside the sound box caused the open strings to produce a tone.  Three test keys produced tones of intermedi...
