Water*
Helpful Hints:
For each category, we have provided several examples to get you
thinking about the wide variety of topics on which you might develop
a website. Remember, your website entry is only required to fit
into one of the broad categories, such as Water.
You will notice that many of our examples include cross-cultural
references or highlight international aspects of a particular
topic. The criteria used to score ThinkQuest entries reward collaboration
among student teams in different regions or countries, so we have
provided examples that we hope will inspire you to think globally
and collaboratively as you choose your topic area and develop
your website.
Here is one way you might choose a topic with your team:
- Look at all six official categories. Which one is most interesting
to you?
- Read the examples provided below. Remember, they are only
examples.
- Then, discuss/brainstorm topic ideas:
- Which ideas are you most excited to learn about?
- If you’re doing ThinkQuest as part of a class, what
are some subjects you will learn about this school term?
In other words, can you think of a topic that links to your
curriculum?
- Are you an expert on a certain topic already? What about
your friends and family? Think about all of the resources
available to you.
- Look at the ThinkQuest Library. Are there already lots
of web sites about your topic? Can you think of something
new?
- Is this a good topic for collaboration—with kids
from another school, community, or country?
Water Examples:
Water is the tie that binds every living thing on our planet,
making this a vast and challenging category for exploration. Consider
these interesting facts:
- The adult human body is 50 to 65 percent water; a child’s
body is approximately 75 percent water.
- An estimated 1.2 billion people do not have access to clean
drinking water.
- Lack of clean drinking water leads to nearly 250 million
cases of water-related disease each year and between 5 and 10
million deaths.
- The Earth has 1,386,000,000 cubic kilometers of water, only
2.5 percent of which is fresh water.
- Of this fresh water, only one tenth of one percent (0.01 percent)
is usable in a renewable fashion.
Explore the topic of water as it relates to people, animals,
health, culture, environment, agriculture, and/or economy. You
might research threats to current water supplies and their effects
on the future well-being of ecosystems, and/or different ways
of providing and conserving water. You might also look at different
uses of water across cultures and geographic regions. We are sure
you will come up with lots of ideas, but here are some examples
to get you started.
Academic Subjects/Standards you could explore in this category:
Language Arts, Physical Science, Life Science, Earth Science,
Social Studies, Civics, and Technology.
Example one: Water-related disease
Freshwater is essential for human survival. However, in many
parts of the world, poor water quality poses a major threat to
human health. An estimated 1.2 billion people do not have access
to clean drinking water and must depend on water sources contaminated
with bacterial and viral organisms, or industrial waste. Over
the next twenty years, 76 million people could die from water
related diseases – that’s more than are threatened
by the global AIDS pandemic -- unless major changes are made.
Example two: Water usage across cultures
The human body can live for weeks without food, but it can only
survive a few days without water. The average person needs a minimum
of 5 liters (1.3 gallons) of water per day to survive in a moderate
climate at an average activity level. The minimum amount recommended
for drinking, cooking, bathing, and sanitation totals 50 liters
(13 gallons). The average person in the United States uses between
250 to 300 liters (65 to 78 gallons) per day for these tasks.
The average person in the Netherlands uses 104 liters (27 gallons)
per day for the same tasks. The average person in Somalia uses
only 8.9 liters (2.3 gallons) per day, much less than the recommended
minimum.
Example three: Pollution’s effects on frogs
In the United States, water pollution is threatening the survival
of fish and amphibians. In 2002, the U.S. Geological Survey tested
139 rivers and found that 80 percent showed evidence of drugs,
hormones, and products such as soaps and perfumes. Here is one
example of how this consumer waste can harm wildlife: A scientist
at the University of Georgia has found that exposure to anti-depressants
in the water can cause tadpoles (immature frogs) to grow much
more slowly than normal. Frogs often lay their eggs in temporary
wetlands, such as ponds that dry up in the summer. If the tadpoles
that hatch from the eggs are exposed to anti-depressants, they
may take a longer time to develop into frogs. If the tadpoles
don’t become frogs before the wetlands evaporate, they die
prematurely, before they can lay their own eggs, changing the
ecosystem.
Example four: Irrigation pump in Africa
The MoneyMaker is a low-cost water pump that is changing the
lives of East African farmers. In the past, farmers had to rely
on carrying buckets of water to irrigate their crops. The MoneyMaker
allows farmers to water larger pieces of land more easily. It
is a portable pump that is powered entirely by foot. It can transport
water from a depth of 23 feet and spray it up to 46 feet in the
air. Farmers who use the MoneyMaker are able to switch from “subsistence
farming” (growing just enough food to feed their families)
to farming as a small business. One example is Janet Ondiak, who
used to struggle to irrigate a small piece of land with buckets
of water. She purchased the MoneyMaker and now operates a vegetable
farm business with three full-time workers. The MoneyMaker was
developed by a nonprofit organization called ApproTEC, who estimate
that the pump has helped create 16,000 new jobs and $30 million
per year in profits and wages.
Example five: Three Gorges Dam
In 1994, the People's Republic of China began a 15-year project
to build a dam across the Yangtze River. When completed, the Three
Gorges Dam will be the world's largest dam and most powerful hydroelectric
power plant, towering 610 feet high and stretching 1.3 miles wide.
It will also create a 400-mile reservoir that will flood 19 counties.
Those who favor building the dam say that it will provide clean,
renewable energy, control natural flooding, and allow big commercial
ships to reach China's interior regions. However, critics warn
that the project may have negative effects on the local environment
and culture. When the dam opens in 2009, over a million people
will have been relocated, over a thousand archeological sites
will be underwater, and endangered species, such as the baiji
dolphin, may be closer to extinction because of changes the dam
will cause to the ecosystem.
