The Water Cycle
Overview:
A group of students let the creative juices flow when they enter the classroom of a "boring" teacher who is teaching the water cycle to her students. They liven things up with a song, dance, and music to demonstrate the steps of the water cycle. After the song, students hold a question and answer session about the different steps in the water cycle.

Water Pollution
Overview:
For this activity, stream table models are utilized. Students introduce pollutants into the sediment in the stream table. Then they introduce water into the stream table and observe the sediment and “downstream” waterway.This demonstration shows how ground pollution and upstream water pollution can be carried downstream to other bodies of water and land. The “ground” in the stream table model has been polluted with green food coloring (before the water is added). As the water passes over the polluted area, the pollution contaminates the stream, surrounding land and the larger body of water at the end of the steam. After polluted water has entered into larger bodies of water (seas, gulfs and oceans), it can be spread to other areas by the Coriolis effect. The Coriolis effect is caused by the rotation of the Earth. The effect deflects objects moving along the surface of the Earth to the right in the Northern hemisphere and to the left in the Southern hemisphere. The resulting movements can cause pollution to spread far beyond its source and affect other parts of the world.

Acid Rain
Overview:
In this activity, the effects that varying pH levels have on plants are tested as a way to see the importance of clean, fresh water to living things. This activity will also demonstrate that water pollution is not just a local issue, but rather a global issue. Explanation: Acid rain is a prime example of how activities in one area can have a serious effect on conditions of a global scale. Acid rain primarily results from the transformation of industrial pollutants such as sulphur dioxide (SO2) and nitrogen oxides into other compounds such as sulphuric acid (H2SO4), and nitric acid (HNO3). This transformation occurs as these pollutants are transported in the atmosphere over distances of hundreds to thousands of kilometers. For example, sulfur dioxide emissions from industrial processes and the burning of fossil fuels have resulted in extensive acid rain and accompanying water pollution problems in southeastern Canada and the northeastern US. These emissions have global implications: more than half of the acid deposition in eastern Canada originates from emissions in the United States. Even slight changes in the pH of lakes and rivers can cause the loss of fish and invertebrates which are important links in the food chain. Acid rain is also responsible for extensive loss of forest cover in that region.

Planet H2O- Bottled - vs- Tap: Which Tastes Better?
Overview:
“Bottled water is a $50 billion-a-year industry worldwide, and people in the United States consume more bottled water than people in any other country. How is it different from what comes out of our taps? Is it really tastier, fresher and healthier – or is that just the advertising hype? The quality of tap water varies depending on where you live, and you can check on the EPA’s Web site to find out if your community’s water meets national standards. For most of us in the United States, tap versus bottled water is a personal choice.”

Planet H2O- Water Pollution and the Aquatic Food Chain
Overview:
Biomagnification is the accumulation of a substance up the food chain by transfer of the pollutant in smaller organisms that are food for larger organisms in the chain. It generally refers to the sequence of processes which results in higher concentrations in organisms at higher levels in the food chain (at higher trophic levels). These processes result in an organism having higher concentrations of a substance than is present in the organism’s food. There is evidence that some carnivores at the ends of longer food chains (e.g. larger fish, birds of prey, HUMANS) can then accumulate the water pollutant from eating down in the food chain. Clean fresh water is vital to life on our planet. What can happen if our waters become polluted? How can that affect us as humans if it is happening in the water and to the organisms in that water? One of the ways pollution impacts humans is through food chains. We have to remember that we are part of the environment and as a result, part of the food chain. We eat many of the aquatic organisms, fish and shellfish, which can be detrimentally affected by water pollution.
