Learning Objectives

  1. Differentiate among atoms, ions, elements, molecules, and compounds.
  2. Discuss how atoms form chemical bonds.

Biology in Real Life

In April 2010, the Deepwater Horizon off-shore oil platform exploded, spilling over 4.9 million barrels of crude oil into the Gulf of Mexico. Since oil floats, the animals most affected by the spill are seabirds that inhabit the surface and the shoreline. This CNN news video highlights the process used to clean the oil-soaked birds.

Video Focus Points

Look for answers to these questions when watching the video:

  • What common household product is used to remove oil from the birds?
  • Why is this product effective in cleaning the oil-soaked birds?
