Well i remember I did a research on hidroelectric plants. And the good thing is you can make aworking model using some water and a bicycle generator hooked to a small light bulb (holiday decoration ones or others like that) also any kind of research that involves things the evaluator can actually see working and moving is always a plus. Just stay away from volcanoes, while they ARE very interesting, its been done quite a few times. Hot air ballons are cool, some china paper glued to make the ballon and a aluminum plate with a candle to keep the air warm (you inflate it with a hair dryer) and you have yourself a working model, plus you have all the data refering how hot air is less dense than cold air etc...there are a lot of cool things you can do out ther and believe me Internet IS going to be VERY useful

Item List:\n\n1. Potato \n2. Plate \n3. 2 pennies \n4. 2 galvanized nails \n5. Three(3) 8 inch lengths insulated copper wire, each with 2 inches of the insulation stripped off one end \n\nHow to do it\n\nFirst, cut a potato in half and put the two halves on a plate so they stand on their flat ends. The plate is there to keep your table clean. Then, wrap the end of one piece of wire around a galvanized nail and wrap the end of a second piece of wire around a penny. Stick the nail and penny into one half of the potato so that they're not touching each other. Next, wrap the third piece of wire around the other penny and put it into the other half of the potato. Put the other nail into the second half of the potato, but this nail should not have wire wrapped around it. Now, connect the wire from the penny on the first half of the potato to the nail that has no wire on it in the second half of the potato. Finally, touch the free ends of the wires to the battery section of the item you are trying to power. One wire goes to the positive(+) connection and the other wire goes to the negative(-) connection.\n \nDoes it work? \n\nYou'll probably have to try connecting the wires to the item in different ways to get the energy to flow through it in the right direction. It's just like putting batteries into a clock; they have to go in the right way.

Thank you for being honest instead of just expecting someone to do your homework for you... you may have to read and comprehend this - but it might help you get done what you need to get done \n\nhttp://www.vtaide.com/png/foodchains.htm\n\ngood luck !!

Not sure what you mean, are you talking about using 2 different metals and generating electricity from a potato?

Hmm, you are in luck.  I am a biologist/chemist with a little ecology and botany knowledge and I might be able to help you out here.  But in the future, procrastination is not the answer.  Trust me, I know.\n\nAnywho, on with your project.  And, kudos to your teach.  He is getting you ready for college.  Lets see, you are wanting to germinate seeds.  It would be feasable to choose seeds with very quick germination times as probably you don't have a very long time to perform this experiment.  Some grasses will germinate in as little as 7 days.  With a little research, you can find your own seeds to use.  Next, you are going to have to decide what treatments you want to apply to each group.  And by each group, you need to have more than one "cup" of seeds, more like 4 or 5.  That is for replication.  By treatments, you could use things like adding different types of fertalizer in each group.  Use fertalizers that differ in the amount of phosphourus, nitrogen, and potassium (3 primary nutrients required by plants.)  Then, with multiple groups recieving the same kinds of fertalizer, vary the amount of sunlight (preferably artificial, like an incandesant lamp) and amount of water given.  What you will end up with is something like this:\n\nfertalizer A - 15 cups; each cup gets 1 tb of fertalizer\n      Cups 1-5 get 10mL of water and 12 hrs of "sunlight" daily\n      Cups 6-10 get 10mL of water and no "sunlight" daily\n      Cups 11-15 get no water and 12 hrs of "sunlight" daily\nRepeat this for say, 3 or 4 different types of fertalizer over a 10 to 15 day period.  Also, have 15 cups that follow the above procedure but get NO fertalizer.  After the 10 to 15 days, compare growth of the plants by measuring (probably in mm) the amount of growth produced.  \n\nBy performing a little research of your own and whatever plant seed you decide to use, you can base your hypothesis on how each fertalizer "should" affect your seeds and how much they "should" grow.\n\nFor example, lets say nitrogen is the main nutrient needed by grass.  Any of the fertalizers used that are low in nitrogen would not grow as much as the ones that get the nitrogen.  And those that do get the nitrogen, the ones that get water and sun will grow more than the others that get only sun or only water.  So, your hypothesis would be something like this:  The seeds that recieve adequate amounts of light, water, and nitrogen will have more growth after x amount of days than the other plants.  Then, you perform the experiment and see what you get.  \n\nGood luck on your experiment and if you remember, let me know what your teach thinks and what grade you get!

Water potential is the tendency of water to move from one place to another. It is typically measured in units of atmospheric pressure: pascals or pounds force per square inch or bars or dynes per square centimeter. It is a measure of the ability of a solution to absorb water by osmosis.

Good Project:\n\nThere have been different attempts all need to be developed yet.\n\nThe attempts include:\n1.Solar energy through silicon cells.\nThis is of more importance in hot regions with maximum sun shine.\n\n2.Ethanol by way of combustion.\nStill an economical method is to be discovered for extracting ethnol from sugarcane.\n\n3.Hydrogen by combustion.\nHydrogen is to be obtained by decomposition of water.\n\n4. Nuclear energy at small scale.\nSo far techniques on domastic production have not been successful.

Probably a contribution of two things:\n\n1. oxidisation of the oxygen in the air\n2. the potato absorbing water from the air.

It's mostly a desert so yeah I would think water and ability to grow anything would be fairly important.\n\nAdmit it.  You want us to help you answer the essay question on your take home exam don't you!!!

stick of dynamite.\n\nOk, I was just being silly, the other two ideas are good.\nA third way might be to create a whirlpool in the water.  I guess you could consider that a hole as well.
