Science project, ideas and experiment on water conservation.


There are many science fair projects that could be done on the subject of water conservation.  You could for example do a project on whether a shower or a bath consumes the most water.
 
The American Water Works Association tells us that the average household uses 350 gallons of water a day or approximately 127,400 gallons a year. Toilets and showers account for 27.7 percent and 17.3 percent of consumption respectively. Washing machines account for about 20.9 percent of indoor residential water use.  Household conservation measures in the bathroom, kitchen, and laundry area can reduce daily water consumption by about 30 percent or 51.9 gallons per person.
 
Many cool and interesting and winning science fair projects for 4th and 5th and 6th grades and elementary students can be made up of different ways ideas and experiments to save water. Turn off the water when shaving, brushing your teeth, and lathering in the shower.
 
Turn faucets completely off to avoid drips. A slow drip (less than 5 drops per second) can waste up to 34 gallons of water a day. Run the dishwasher and washing machine only when full.  Adjust the water level on the washing machine when doing less than a full load of laundry. You could do a science project or experiment on how to wash veggies and fruit and save water.
Avoid running water when washing fruits and vegetables. Washing in a bowl conserves water.
 
Take a shower instead of a bath. The amount of water needed to fill a tub varies, but on average, a bath uses 15 to 25 gallons of hot water, compared to less than 10 gallons for a shower. Take short showers. An efficient 4-minute shower uses 10 gallons of water compared to an 8-minute shower, which uses about 17 gallons of water.
 
An elementary or high school project could be done on efficient toilets.  Replace present showerheads with low-flow showerheads. All new showerheads are required by law to restrict water flow to 2.5 gallons per minute or less.
 
Install aerators on all faucets. Aerators are inexpensive, easy to install, and can reduce daily faucet water use by 13 percent. Research can be done for a science project, idea or experiment on aerators and how much water they really save. Experiments in chemistry, biology, physics and computer sciences are really interesting but so is the subject of water conservation. Repair leaks because they account for 14 percent of household water use.
 
Install low-flush toilets that use 1.5 gallons of water per flush, compared to 3 to 5 gallons per flush used by conventional toilets. A toilet dam can also be installed to conserve water.
Replace your old washing machine with a more efficient model. Studies show that newer models can result in a 68 percent energy savings and a 38 percent water savings. Some utilities may provide incentives for buying new washing machines.
 
You could do research on how much water your washing machine uses and compare this figure with your friends, neighbors and family and imagine what a good science fair topic this could be for junior high school.
 
You can have a water audit done to measure household water consumption and can help detect water leaks. To detect leaks, set aside a time (30 minutes to an hour) when no water will be used in the house. Check the water meter before and after the time. If the meter reading changes, a leak is likely.
