Transcript of Ocean Motion

You will need:
• an empty plastic bottle with a lid
• clear vegetable oil or any kind of oil
• water
• a funnel
• blue food coloring/any kind of color but its better to use blue
Procedure:
1. First, fill the bottle halfway with water. Add a few drops of blue food coloring and swirl it around until it mixes.

2. Using a funnel, add oil or mineral spirits up to the top of the bottle. Put the lid on tightly.

3. Now rock the bottle on it’s side gently to create a wave that goes back and forth.

Within our own little ocean bottle, the oil and water don’t mix because the hydrogen bonds in the water are strong. The oil bonds are not strong enough to break the water’s hydrogen bonds, so the two liquids can’t combine. The oil is less dense than the water, so it stays above it and allows us to see the wave action we see when we tip the bottle back and forth. When oil spills happen within our oceans, those two substances won’t mix either.
The Science behind it
Waves in the ocean are movements that carry energy from one place to another. Waves need to travel through a medium like water. When you see a wave, the water doesn't cause the waves. The energy in the water causes the waves to form. In this experiment, the energy for the waves in the bottle came from you.
What does the motion of a wave look like?
Observe with a wave in a bottle.
If you want to, you may add small shells, sand, or tiny fish-shaped beads and any chu-chu before sealing the bottle.
Instead, they leave disastrous oil spills that are difficult to clean up and can harm plant and animal life in the area they spilled. To keep things in perspective though, more oil reaches the oceans each year in little bits from leaking automobiles and things than has ever spilled off an oil tanker. When tankers leak it looks dramatic because it’s all in one place, but there are bits of oil being dripped in from other sources far more.
