According
to current information from the U. S. Census Bureau, the world's population
increases by about 250 people every minute. Find out how fast the world's
population is growing by investigating this data. How large is the human
population expected to be in 10 years?
Visit
this page to see POPClocks, which provide estimates of the U.S. and world
populations as well as indications of how fast these groups are growing. Record
the date and time the first time you visit this site. What are the current U.S.
and world population estimates? Visit this site again in a few days. How much
has the U.S. and world population grown in that period of time?

On
the Move…Continental Drift and Plate Tectonics is a page on the NASA Web
site. Click the Interactive Map link to match continents' names and
locations from 250 million years ago. Click the links at the bottom of the page
to read more about continental drift. Why should continental drift matter to
you?
Read
about Alfred Wegener, the German meteorologist who proposed the theory of
continental drift, the shifting of Earth's crust. Visit Pangaea.com to read
about how Wegener came understand continental drift and compare it to a
geographical jigsaw puzzle. What were some of Wegener's specific pieces of
evidence to support continental drift?

Visit
this site to find out about sound navigation and ranging (sonar). Scroll down to
read about active and passive sonar systems. Dolphins use a type of sonar called
echolocation underwater to locate prey. Do dolphins use active or passive sonar?
Go to
this site to learn all about sonar. Scroll down to read about how sonar works,
why it is important, and who uses it. How might sonar be used in the future?
At this
site you can learn more about how sonar can help you see with sound waves. Watch
the animation of a towed sonar array and read the captions. Then click on find
out what sonar is used for. How is sonar used by people who fish for a
living?

Visit
this site to learn about light, reflection, refraction, and dispersion. Scroll
down to lenses. What two optical devices use convex lenses to focus light?
Go to
this site to learn more about convex and concave lenses and how they cause light
waves to converge or diverge, respectively. Scroll down to read about single
lenses. What optical devices use the convex lens for simple magnification?
