Is there a good movie for 5th Graders that shows the water cycle or water pollution or the energy cycle?

Thanks for any help. It really needs to be G rated.

I just watched a movie in my 9th grade class about the water cycle about a week ago. Too bad im too darn lazy to ask my science teacher about it =]

Here’s what I have so far:

People can help prevent water pollution by recycling and disposing of their waste safely and properly. Although laws already exist about dumping, they should be more strict and more enforced to prevent people or companies from getting away with it. Water treatments facilities should be available in every area.

I need a paragraph, though - that’s not enough.

Ideas?

Don’t forget agricultural pollution from fertilizers and pesticides. Buffer zones of vegetation can protect bodies of water.

There are also heat pollution, as from cooling water, acid water from mines, and airborne particles that settle out. That should get you a good fat paragraph once you elaborate.

I need solutions to water pollution to my natural resources project for geography!
FINAL PROJECT for this semester!!!

Please help!!!

Thanks!
Look up Lake Erie and the solutions to the pollution there. I remember when the lake caught fire because of all the pollution. Nowadays it is the number one walleye and smallmouth bass capitol of the world. A true victory for sportsmen.

Hi friends, As you all know the biggest problem in our country is water pollution which causes lots of diseases. To save myself I got a link with some good tips

http://www.tictacdo.com/ttd/How_to_protect_yourself_from_water_pollution

But getting difficulty in 3rd point.
Can anyone suggest me?

well, that is a very good question. the best way to prtect yourself is to not drink water, DUH.

I Have A Science Fair Project coming up and i have never done a science fair project so this would really help. My question is How much pollution can water take before it becomes unsafe? I do not have a hypothesis yet or the data =[

What are the common sources of ground water pollution and how do they enter the aquifers?

Saltwater encroachment associated with over drafting of aquifers or natural leaching from natural occurring deposits are natural sources of groundwater pollution. Most concern over groundwater contamination has centered on pollution associated with human activities. Human groundwater contamination can be related to waste disposal (private sewage disposal systems, land disposal of solid waste, municipal wastewater, wastewater impoundments, land spreading of sludge, brine disposal from the petroleum industry, mine wastes, deep-well disposal of liquid wastes, animal feedlot wastes, radioactive wastes) or not directly related to waste disposal (accidents, certain agricultural activities, mining, highway deicing, acid rain, improper well construction and maintenance, road salt).
Large quantities of organic compounds are manufactured and used by industries, agriculture and municipalities. These man-made organic compounds are of most concern. The organic compounds occur in nature and may come from natural sources as well as from human activities. In many locations groundwater has been contaminated by chemicals for many decades, though this form of pollution was not recognized as serious environmental problem until the 1980s.
A brief description of the contamination sources follows.
1. Natural: groundwater contains some impurities, even if it is unaffected by human activities. The types and concentrations of natural impurities depend on the nature of the geological material through which the groundwater moves and the quality of the recharge water. Groundwater moving through sedimentary rocks and soils may pick up a wide range of compounds such as magnesium, calcium, and chlorides. Some aquifers have high natural concentration of dissolved constituents such as arsenic, boron, and selenium. The effect of these natural sources of contamination on groundwater quality depends on the type of contaminant and its concentrations.
2. Agricultural: Pesticides, fertilizers, herbicides and animal waste are agricultural sources of groundwater contamination. The agricultural contamination sources are varied and numerous: spillage of fertilizers and pesticides during handling, runoff from the loading and washing of pesticide sprayers or other application equipment, using chemicals uphill from or within a few hundred feet of a well. Agricultural land that lacks sufficient drainage is considered by many farmers to be lost income land. So they may install drain tiles or drainage wells to make the land more productive. The drainage well then serves as a direct conduit to groundwater for agricultural wastes which are washed down with the runoff.
Storage of agricultural chemicals near conduits to groundwater, such as open and abandoned wells, sink holes, or surface depressions where ponded water is likely to accumulate. Contamination may also occur when chemicals are stored in uncovered areas, unprotected from wind and rain, or are stored in locations where the groundwater flows from the direction of the chemical storage to the well.
3. Industrial: Manufacturing and service industries have high demands for cooling water, processing water and water for cleaning purposes. Groundwater pollution occurs when used water is returned to the hydrological cycle.
Modern economic activity requires transportation and storage of material used in manufacturing, processing, and construction. Along the way, some of this material can be lost through spillage, leakage, or improper handling. The disposal of wastes associated with the above activities contributes to another source of groundwater contamination. Some businesses, usually without access to sewer systems, rely on shallow underground disposal. They use cesspools or dry holes, or send the wastewater into septic tanks. Any of these forms of disposal can lead to contamination of underground sources of drinking water. Dry holes and cesspools introduce wastes directly into the ground. Septic systems cannot treat industrial wastes. Wastewater disposal practices of certain types of businesses, such as automobile service stations, dry cleaners, electrical component or machine manufacturers, photo processors, and metal platters or fabricators are of particular concern because the waste they generate is likely to contain toxic chemicals. Other industrial sources of contamination include cleaning off holding tanks or spraying equipment on the open ground, disposing of waste in septic systems or dry wells, and storing hazardous materials in uncovered areas or in areas that do not have pads with drains or catchment basins. Underground and above ground storage tanks holding petroleum products, acids, solvents and chemicals can develop leaks from corrosion, defects, improper installation, or mechanical failure of the pipes and fittings. Mining of fuel and non-fuel minerals can create many opportunities for groundwater contamination. The problems stem from the mining process itself, disposal of wastes,
and processing of the ores and the wastes it creates.
4. Residential: Residential wastewater systems can be a source of many categories of contaminants, including bacteria, viruses, nitrates from human waste, and organic compounds. Injection wells used for domestic wastewater disposal (septic systems, cesspools, drainage wells for storm water runoff, groundwater recharge wells) are of particular concern to groundwater quality if located close to drinking water wells. Improperly storing or disposing of household chemicals such as paints, synthetic detergents, solvents, oils, medicines, disinfectants, pool chemicals, pesticides, batteries, gasoline and diesel fuel can lead to groundwater contamination. When stored in garages or basements with floor drains, spills and flooding may introduce such contaminants into the groundwater. When thrown in the household trash, the products will eventually be carried into the groundwater because community landfills are not equipped to handle hazardous materials. Similarly, wastes dumped or buried in the ground can contaminate the soil and leach into the groundwater.

we have a long project on water pollution and i need ur help in this one cuz im not finding enough information. nd thanks if u helped me :):)

Acid rain is a pollution problem. Small amounts of Sulfur and its oxides in the air combine with cloud moisture to produce acid rain. This acid rain washes into lakes, streams, and rivers having a negative impact on the wildlife that lives there.

and how is the economy affecting water pollution?

i dont know about the first one but
for the economy there is a lot ofcompetitionn so peopledon’tt care where they
throw away all the chemicals in lakes and alot of fresh water places. they justdon’tt care that what they are doing is not going to help them out, all they care about is the money they make.

Laura, I think your question contains the answer. People don’t care, and
many of them just don’t believe that WE are the problem. It is nice to know
that you are thinking of pollution and ways to solve the problem.

I have the Action Plan for Clean Water already from the Environmental Canada website. Can anyone give me more information about what they are doing? I’m writing an essay about water pollution.

Also, what other factors do industries have to not get rid of chemicals properly other than the cost?
Thank you : )
the links helped very much, thanks.
i actually just stumbled across the environmental act : )

first is to check the canadian environmental act : http://www.ec.gc.ca/CEPARegistry/the_act/
here are current regulations:

hope the links helped

Is water pollution one reason why we are in a water shortage?

I’m doing a research paper on water conservation, and i just want to know how pollution relates to the the shortage.
I’ve done research but i cant find anything about both of them together.

Not quite sure if you’re simply looking to see if there is a link or attempting to prove that one is there, however; the way I see it is that water availability is dictated by numerous factors ranging from ocean temperature, season, elevation, vegetation, land formation, etc. When there is not enough water available due to drought years and/or excessive unrestricted water consumption there becomes a water shortage.

As to water pollution, this is contaminating the fresh water supply in a way that it could decrease the amount of safe fresh water during a water shortage, OR it could contaminate fresh water to a degree that there becomes a shortage of potable safe fresh water available.

That last one is probably the link you’re looking for.
