This activity uses Ozone Watch to explore seasonal ozone hole
data. Students use real ozone data to answer questions.

This activity is associated with studies of surface ozone
but can serve studies of stratospheric ozone as well.
The purpose of the activity is to construct a model that
will provide students with a visual representation of
parts per billion. Students work in teams to construct
cubes of different volumes and to compare them to get a
feel for parts per million by volume and parts per
billion by volume. The intended outcome is that students
gain a feeling for the small quantities of gases, such as
ozone, present in the Earth's atmosphere.

UV Menace is one module among several on-line, problem-based
modules developed by NASA's
Classroom of the Future.
Students evaluate the latest status of the Montreal Protocol
and determine if it adequately considers the
interrelationship of Earth's spheres. To do this, they must
investigate how an event in one sphere may have an effect in
a second sphere, which may, in turn, affect a third sphere.
Students must be prepared to defend their recommendations.

Ozone depletion information from the United States
Environmental Protection Agency. The site contains
sections on ozone science, the regulatory approach to
protecting the ozone layer, and educational information on
sun safety.

Most ozone resides in the stratosphere, where it acts as a
shield to protect Earth's surface from the sun's harmful
ultraviolet radiation. With a weakening of this shield, we
would be more susceptible to skin cancer, cataracts, and
impaired immune systems.

New remote-sensing technology called limb viewing allows
observation of the atmosphere from the side rather than
straight down, as with current earth observation
satellites. From the side, the layers of the atmosphere
appear like layers in a cake, allowing instruments like
SOLSE-2 to see the lower layers of the stratosphere. A
successful science mission by the Space Shuttle Columbia
crew before their tragic loss during re-entry into
Earth’s atmosphere established limb-viewing as a
valid approach to studying Earth's ozone.

Over recent decades the stratosphere has cooled while
stratospheric ozone has decreased. Low temperatures could
be causing further ozone depletion, which may delay
recovery of the ozone layer.
Grade level: All
Massive solar flares that erupted during July, 2000
emitted high energy protons which stripped away some of
the ozone in the Earth's atmosphere.

NASA Wavelength is your pathway into a digital collection of Earth
and space science resources for educators of all levels. These
resources, developed through funding of the NASA Science Mission
Directorate (SMD), have undergone a peer-review process through
which educators and scientists ensure the content is accurate and
useful in an educational setting. Use NASA Wavelength to quickly
and easily locate resources, connect them to other websites using
atom feeds, and even share the resources you discover with others
through social media and email.
