So by being able to scrub the air and take out all the toxins, you do great things for air pollution. But those toxins have to go somewhere and once they're trapped in this liquid - and many of them dissolve in the liquid - they have to do something with the liquid.

So what coal-fired power plants do is one of two things - the first of which is, they put them in these huge ponds or landfills. And in December, I'm sure you remember, one of these ponds - the dam burst in Tennessee, and it flooded over a billion gallons of these toxins on nearby areas.

If they don't put them in these big ponds or landfills, what they do is they have to dump them into rivers. And so in a sense, you're taking the pollution out of the air, but you're putting it in the water.

Several aspects of young children's learning are important to consider when
thinking about art and creative activities (Edwards & Hiler, 1993). First,
young children are developmentally capable of classroom experiences which call
for (and practice) higher level thinking skills, including ANALYSIS (breaking
down material into component parts to understand the structure, seeing
similarities and differences); SYNTHESIS (putting parts together to form a new
whole, rearranging, reorganizing); and EVALUATION (judging the value of material
based on definite criteria).

Second, young children want and need to express ideas and messages through
many different expressive avenues and symbolic media. Young children form mental
images, represent their ideas, and communicate with the world in a combination
of ways. They need increasing competence and integration across formats
including words, gestures, drawings, paintings, sculpture, construction, music,
dramatic play, movement, and dance. Through sharing and gaining others'
perspectives, and then revisiting and revising their work, children move to new
levels of awareness. Teachers act as guides, careful not to impose adult ideas
and beliefs upon the children.

Third, young children learn through meaningful activities in which different
subject areas are integrated. Open-ended discussions and long-term activities
bring together whole-language activities, science, social studies, dramatic
play, and artistic creation. Activities that are meaningful and relevant to the
child's life experiences provide opportunities to teach across the curriculum
and assist children in seeing the interrelationships of things they are
learning.
