Why are leaking landfills and septic tanks a concern to people who use groundwater?
What comes out of the landfills and septic tanks goes into the water. I would rather not drink someone's sewage.
What is a acknowledgements on a science fair project?
It is to acknowledge the people that helped you with your board.
Not sure what you mean, but: For practical purposes, it is sometimes convenient to treat matter and energy as two different things. On the other hand, according to the Special Theory of Relativity, every energy has associated mass - this more or less puts matter and energy on the same level.
What are all the Good science project topics?
There are various topics in computer science such as theory of computation, analysis of algorithms, formal methods, concurrency theory, databases, computer graphics and systems analysis, among others. computer programming is the main topic in computer science, but treat it as a vessel for the support of other fields of computer science rather than a central focus of high-level study.
Does baking soda dissolve better in hot warm or cold water?
To dissolve baking soda in hot water one would need to pour hot water on the baking soda and stir it with a spoon. Baking soda that is dissolved has lessens the leavening action of the soda.

Can a potato light a 60 watt light bulb?
If you're talking about the standard 60-watt lamp, no. It is true that by assembling the correct components and "plugging them into" the spud, you can make a simple electrochemical cell, but this cell won't generate the voltage or the current to drive the lamp enough to light it up. Not even a little bit.
The life of professor errol Morris the Jamaican scientist?
The name of the Jamaican scientist is actually named Errol Morrison versus Errol Morris. He attended the University of the West Indies, University College London, and the Royal University of Malta. He has done extensive research pertaining to diabetes.
What percentage of an orange is water?
The percentage of water in an orange is 50 percent.
According to USDA data, an orange, not including its seeds, is about 82% water by weight, including the peel. If the peel is excluded then the percentage goes up to 88%. Orange peel by itself is about 73% water.
Why aren't experiments always accurate?
It depends on what kind of experiment you are performing, an experiment can never be entirely accurate but the more times you perform them, the more of an accurate result you will get.
Answer:
An experiment in a school lab is more correctly a demonstration. The errors are caused by unfamiliarity with the equipment, methods, or recording of results.
In a research laboratory an experiment is reaching into new areas. The potential variables are not all known. Lack of the control of these variables can cause error in the results.
Which would cool down quicker in a fridge - a full bottle of water or half a bottle of water?
A half bottle because small bodies cool down faster. Like a emporer penguin chick out in the open. The chick would freeze to death quick, that's why they try to say with their parents. Or why you cant blow on a whole bowl of hot soup to cool it down.
How can a dry cell produce electrical energy?
A "dry" cell is actually a misnomer. The electrolyte is actually a moist paste, with enough liquid in it to make the electrochemistry operate exactly the same as a wet cell. The practical difference between a dry cell and a wet cell is that the moist paste electrolyte of the dry cell will not spill out when the cell is turned over like the liquid electrolyte of the wet cell does. This makes manufacturing and transportation of ready to use dry cells possible, while wet cells must be manufactured and shipped without the liquid electrolyte and are filled at the point of sale after installation.
What are thing that are kept the same throughout an experiment?
You have to keep the timing the same, and you have to keep the same amount of each thing the same.
How do you find out science fair project answers?
Go to science buddies.com or go to google and search science fair projects.
A dependent variable is what is being measured in the experiment. Such as time, distance, volume, etc.
Yes
Does the density of water change as a function of dissolved salt?
Yes, the density of water increases as salt is dissolved in it. This is because the salt adds mass to the water without significantly changing its volume. The increase in density allows objects to float more easily in saltwater compared to freshwater.
What should the independent variable be?
The answer depends on what the experiment is about.
For example, if you believe (or want to test) that pupils' scores in English tests depend on their scores in maths tests, then the independent variable is the maths score. But if you believe that the English scores influence their maths scores then the independent variable is the maths score.

1)Allooo kia dozen chal raha hain..?
2)doodh kia kilo mil raha hai...?
3)kuttoun ki mardam shumari ka lia..?
4)how many people wash their socks daily...?
