Explain why is a good source to use. Into what kinds of energy will these be changed into in order for your colony to succeed? What living conditions eill you need for the people in your colony? will you simulate "seasons" or periods of "day" or "night" or will everything be the same, all the time? How will people adapt to this? How will you get food? What kind of plants would you grow? Why would they be good ? WILL YOU USE SOIL OR WATER?

Solar energy ( using solar panels or something ) is the ultimate alternate energy source, because the energy in living things comes from the sun.  The energy in petroleum, which comes from dead plants, comes from the sun.  And the energy from hydroelectric dams comes from the sun, because the sun evaporates the water so it can rain down on the mountains and fill up the reservoir behind the dam.  Why not just go directly to the source--the sun.\n\nAs for simulating day and night, you must do this!  The human body schedules itself to sleep about every 24 or 25 hours.  Going against this schedule or against the schedule of light and dark periods can cause difficulty sleeping, difficulty staying awake, and possibly psychological problems.\n\nI don't really know what kind of colony you are referring to, so I can't really answer the other questions.  Is it a computer simulation, like Sim City, or a science-fiction colony on the planet Mars, or just a wilderness survival plan?

there is a whole science that adresses exactly what you mention\nWATER HARVESTING\n,dig small dams every where to cath the rain water, and you can archieve that all of the rain water is absorbed by the land ,it will seep slowly into the ground to add to subteranean water suplies ,make sure that all the dams are interconnected by slow gradient ditches .just because you dont see water ,does not mean that it is not there .\nNormally a land repels water and with the rains it runs over ground into the rivers and awy.\nthink now that you want to make the land receptive or absorbent of all the water that falls on it.\n\nMULCH\ncut down the weeds before they produce seeds and leave them where they fall,they will cover the ground and put even more organic matter on top,you can use saw dust,leaves green or dry,and when you plant make a little space and plant in the mulch.this is the easiest quickest and by far most benificial way(for the quality of you soul)to prepare the land for planting\n\nto prevent weeds from coming all you have to do it turn out the lights,you can even use cardboard or black plastic(this is good for strawberries because they will rot if they touch humid ground,and the bugs can get to them).\n\nwhat you do is to cover the ground with mulch which is the same principal as compost but it includes the whole garden surface\nthe top part of the soil where the topsoil is being produced houses a world or microbiotic life.\n\nMulch is organic material green or dry that covers the ground,the thicker the better the composting process will turn it in to black topsoil\n\nthe humidity is preserved underneath and promotes the devellopment of worms(their exists no better compost than their excrements)and a variety of micro biotic life which together with the mulch produce more topsoil.\n\nthe mulch also keeps the ground temperature even and guards against the impact of the rain ,which would other wise brings salt to the surfave if on unprotected land\n\nMulch also prevents the soil from drying out because of the sun and, lay it open to wind erosian.\n\nand it turn out the lights for any weeds that want to come up\ndo not use chemicals because the water will wash them into the ground and if enough people did that, you would be guilty of helping to contaminate subteranean water suplies that other people could be pumping up to drink \n\nSUSTAINABLE FARMING\nthe best examples on this Earth of sustainable agriculture,\nare the chinampas of central Mexico ,the surviving ones(that have not been consumed by urban devellopment)have been going for more than 800 years ,that is sustainability.\nthe are built from the mud of the lakes and enriched with compost ,in the old days with the toilet contents of the outhouses that were on the bridges going into town,which the indians collected with a canoo.\n\nAnother example are the traced gardens of the Inca which have been going for more than a thousand years,there success is also because of the principle of using compost and their form which id a receptive concave absorb the rain waters and collect the dust from the wind (for hundreds of years and so increase in quality instead of the oposite.\nin the Ukraine are also examples of ancient agriculture due to no till farming and mulching(green organic matter that is added)\n\nin Mexico today are still examples from old Indian agricultural practises of diversity or companion planting.\nwhere by a series of 7 or 8 species of plants are put together or one folows the other.to create biodiversity ,and utilisation of space.\nCorn is planted for example ,wich is followed 4 weeks later by a bean that climbs it.\nand agavi and edible cactus is on the sides to protect these plants from foraging animals and add chemicals to the soil by their secretions.and others are in between to provide groundcover\n\nthere are many forms of sustainable farming in the past,and today those who follow the principles of permaculture,no till farming,organic or sustainable farmin

How much time do you have?  If you have a few weeks....\n\nGet 5 of the same type of plant.\n\nMake sure they all have the same conditions.  Same type of soil/amount   Same amount of light/temp.  If using lamps, make sure they get the same amount of lamp time.\n\nThe goal is to keep all conditions the same aside from the one variable you will be testing... \n\nSo on to the variable.  Pick 5 different substances that you will give them for fluids... IE...\n\n1. Water  2. Soda   3. Bleach   4. Miracle grow or other plant food mixxed with water.   5. Orance juice.\n\nOkay.  Water will be your control group.  You will use this as a base line to compare all of the others to.  You can of course pick whatever you want for fluids. Those are just some ideas pick whatever fluids you want.  Always make sure to have a control group (the one with water) so you have something as a base line.\n\nGive them all 25 milliliters of the subtance each day. The amount you give them depends on what plant you pick, and its size, adjust accordingly. Make sure to feed them at the same time each day.\n\nBefore you start, write down your hypothesis.. \nHow do you think each plant will do? and why?\n\nTwice a week write down how the plants look.\nHow much they have grown.\nThe plants overall health.\nAlso, write down anything else you have noticed. i.e change in color, a plant dying.  \n\nThen compare it with the plant just getting plain water.  It is doing better than the control?  worse?  same? \n\nAt the end of each week make a theory on how you think the plant will do over the next week.\n\nMake sure to factor out all variable, and keep everything aside from the substance they get the exact same.\n\nWhen done with the experiment write a conclusion.  Was your hypothesis correct? What were you right about? What were you wrong about? How did each plant fair?  What could you have changed to make the experiment more accurate??  Did you do anytyhing wrong? ie mistakenly change something?  If you repeated the experiment, do you think the results would be the same? why or why not?\n\nMake sure to fully explain all of your statements. Charts or graphs of the results are always nice.\n\nThis would work the best if you started them from seed, but you prob don't have that kind of time span.  \n\nIf this is to childish of an experiment, maybe do a plant stem grafting experiment, or a cross-pollination between plants of the same species. i.e make a hybrid plant from 2 differnt types of tomatos or different flowers.

Are you 15+? Then, you can consider the following:\n\nThis is a project based on Astronomy! Try to simulate our solar and lunar systems around each planet. Bring in the real feel of how plants rotate around sun and how moons rotate around its planets.

Take your pick:\n\nbirds leave viable seeds in their droppings\nseeds drift in wind\nseeds catch on fur / clothing, and drop off, later\nseeds are found to be useful to humans, and we spread them\nwater (eg coconuts float, landing on distant shores, and sprouting)\n\nI am sure there are other ways...

The sun is not the source of ALL the energy - just almost all of it.  \n\nLight is a form of energy, most of our light is from the sun but we do recieve a tiny fraction of light from the other stars in the sky - that is why we can see them.\n\nBut the sun does supply almost all the energy.\nThe sun radiates light and other forms of energy which hits the earth and some is absorbed (some is also reflected).  Much of the absorbed light becomes heat - this is why it is hotter in the sunshine than the shade.\nSunlight also allows plants to obtain energy by a process called photosynthasis which happens in leaves and green stalks (like on a cactus).  It is this energy from sunlight which allows plants to grow.  All living things use this energy from plants via the food chain.\nFuels (like coal and oil) come from the remains of plants and animals and thus the energy was originally from the sun.\n\nThere are sources of energy which don't come from the sun such as geothermal power (this is heat from the centre of the earth which is created by pressure) and there are even organisms which live deep in the ocean which do not need any sunlight to survive (they are chemotrophic bacteria which survive around active volcanic vents in the sea floor).  \nBut to all intents and purposes a good 99% of all the energy comes from the sun.\n\nI hope this helps you with your homework!

Show the logistics of building a space station. i.e. First you would have to get a few modules built, then stock the modules with what you would need to continue. Figure in you are only allow to carry a limited amount of weight every time the shuttle leaves Earth. What would you bring first, second, third, etc. Who would you need to have up there? A pilot of the shuttle, some mechanics, maybe a physician - when would you be able to add solar panels for power? You can make it as involved as you want to.

Oil can be found on an island -- so can gold, platinum, or any number of other things. If your island is next to Africa, you already know something about what its climate might be like, and that gives you a clue as to what crops might be grown, or what plants already exist. You can populate your island with whatever kind of animals you want, as long as you stay away from the obvious cop outs like polar bears and penguins. \nSounds like a fun project. Good luck with it!

Show a floating ring gear assembly and ask how clean free energy can be produced from it. If you are smart and belive in God and Jesus, you will be allowed to see how it works. It has taken me over thirty years to see the final answer, but it was worth the pursuit. Upon seeing and understanding how it works, the rush is on as to who first presents it to the rest of the world in a working model. May you be a person of God and Jesus and then you will see how it is built. Trust me, it can be done. Dave.

Most life on Earth is powered by the Sun. Plants use Photosynthesis to make carbohydrates from the Sun. Animals eat Plants, we eat both plants and animals that eat plants. Therefore indirectly virtually all of our food energy comes from the Sun. Our Brain uses our food energy to operate. Therefore our brain is powered by the Sun.

Please don't give your plant a vitamin made for a human. The plant is energetically connected to you now. Just from sharing in your space. It would be in your best intrest to take very good care of the plant. It will bring you prosperity.

In the context of your question,\n\nA resource is a source of material or energy that may be consumed, changed, or dispersed to the point it is no longer easily usable. Examples would be copper ore, oxygen in the atmosphere, helium gas taken from oil wells, water, sand, or even soil. Anything we do consumes or utilizes some sort of resource. Breathing uses oxygen from the air. Copper is used for wiring and piping. Helium is used for scientific research and birthday balloons. Sand is used to make concrete. Water is used for drinking, irrigation, and generating hydroelectric power. Soil is used for growing crops.  None of these are exhaustive lists, just examples. \n\nOil: Oil is a mixture of organic compounds extracted from the earth by drilling. It is created from organic materials deposited in sedimentary rock that are altered by heat, pressure, and biotic processes to create it. \nOil is used to make gasoline, diesel, airplane fuel, plastic, shampoo, rubber, antihistamines, and many other products. \n\nNatural gas: It is an organic gas that is also extracted from the earth by drilling. It is generated by a similar process to that for oil generation. It is used to heat homes, make fertilizer, and some plastics. \n\nWater: Water is found in many forms, but mostly as either fresh or saltwater. Fresh water is used for drinking, irrigation, etc. Saltwater is not as useful directly to man, but is an essential part of our environment as the oceans both support food supplies and have a large effect on the climate. \n\nWood: Wood comes from living organisms- trees. Wood can be used for building many things, including houses. It is used for fuel and is the primary source of fuel in some parts of the world.

easiest thing ever is plants. Get 3 plants and water them with regular water, and 3 other plants and water them with regular water and add fertilizer like Miracle Grow, then 3 more and water them with sugar-water. then hypothesize which will grow better.

It would be different from country to country, but I think you have the basics as to what they would probably do. The geography and the social structure of the area would play a big part as to what would be grown in the soil and what livestock they would raise. Here are some links for you to check out:

Usually, plants take nutrients from the soil and air and use it for fuel for their growth. Animals tap into this cycle by eating plants during this process. A plant species doesn't want to die, so it adapts to make itself harder to eat (thorny, poisonous, hard bark, etc.) and maybe also to take advantage of animal behavior to propogate itself (fruits, nuts, etc.). Animals who can't get easy plant food any more need to adapt too (resistance to poison), and may begin working with the plant to propogate their food source in return for an easy and sometimes exclusive snack or shelter (hummingbirds, etc.). Rarely, plants adapt to the presence of animal food as a booster source of nutrients, especially in nutrient-poor soil (venus fly traps, etc.). Sometimes, plants and animals come to work in such close cooperation that neither would easily survive without the other (honeybees and flowers).\n\nAdaption and evolution is the best way to describe the interactions between plants and animals in a systematic sense.

Yet another interesting question, man_id.\n\nAll a theory of abiogenesis can do is give an answer for how life-from-non-life is *possible*.  ... I.e. what ingredients and conditions might result in a replication system that is sufficient for natural selection to take over?  And which ones *may* have been present in the early days of the earth (knowing what we do know about those days)?  There may, in fact, be multiple answers ... many different recipes, all equally possible.  If so, then we may never know which one actually occurred on our planet.\n\nBut it is also possible that we may never find a recipe that works that we know might have been available in the earth's infancy.  We've only started looking.

ummm everybody seems to have the same answer but yeah\nim assuming your in gr......7 science?\njust cause thats what i am referring to right now in my head:\n\na producer: like a plant/ something that makes its own food[bottom of food chain]\n\nconsumer: an animal/ something that need food by eating something else.\nthere are a bunch of types of producers but i dont remember the names cuz it was too long ago i think it was...so i will number them\n1: 2nd lowest it only eats plants\n2: eats plants and things that eat plants [3rd lowest]\n3: things that eat plants and animals that eat plant/ plants and animals.[highest/us!]\n\nif 1 animal were to lose its habitat, the plant eater would have no food and it would die and then the 2 woulod be able to eat nothing and the 3 would be able to eat nothing cuz the animals and the plants died. its an ecosystem...ect.....symbiosism....ect..\n\nand included in that test should be some stuff about decomposition or something like that\n..\n..\nand some stuff about \nmutualism; when 2 things are benifiting \nex: the sharks and the suckers\n\n__________.[i forgot]; when i thing benifits but the other is not harmed\nex: i cant think of one right now...but it exsists!\n\nparasitism; when i thing benifits and the other is harmed\nex: a tapeworm in a human\n\nendnote: ppl will see this answer and answer it better based on my answer so *cough*i think i should get best answer*endcough* and i totaly am just typing this out of my brain what i learnt 2 years ago so i dont remember much ^_^"""
