how could i isolate cyanobacteria and from where and how to cultivate it ?

To isolate it, take a sample, dilute it then take a sample from that & spread it on a sterile petri-dish.\n\nYou can then take a sample from a pure culture.

you could make antibiotic/antiviral resistant strains of viruses or bacterea. change the genetics of plants to create more of a certain toxin so you can get a greater yield of toxin per plant. The most efficient way to distribute the toxin would be through the water supply. many places either do not check their water or do not check it well enough.

Burn the paper and mix the carbon leftovers with the water. You should get some killer jailhouse results.

Find a question that relates to the local area you live in, something you may have noticed, or has controversy.  A saying I like is "One measurement is worth a thousand expert opinions", which is the essence of science.  So find something to measure.  When I was in school (a long time ago) people I knew wondered about whether the local creek was clean enough.  Kids played in the creek and some people fished in it, but I thought it shouldn't foam and have a not quite clear look.  So, I got some sterile petri dishes from the biology lab, got some q-tips, and talked the local hospital pathologist into helping me.  If you need help, ask, you might be surprised, it turned out he was curious too.  Anyway, I learned a bit about how to identify bacteria and yes, the creek was polluted-bad!  I made the front page of the local paper.  I'm not saying do this, but think of a local problem and measure it.  Hope this helps.

get yourself some pond water, theres more stuff to look at in there that just about anything else.\n\nRubbing alcohol is ok for sterilising, unless your using stuff thats potentually dangerous it will do.\n\nIn your petri dish you put Agar, it's jelly stuff u can buy it  in sachets, its made from seaweed, when u are mixing it up with water u add a drop of nutrient solution, normally specific to what your trying to grow.  The find yourself some bacteria or mold and put them in the petri dish, cover it up and watch.

Try a mini ecosystem in a 2-liter coke bottle. Study it for a few months and see how it changes. Record what plants and animals you put in too.I suggest putting in some worms, moss, and an up-right plant

The latest technology is bio extraction using plants and microbes to extract gold from the source rocks.\n\nI suggest that you go in for cyanide method. Not free cyanides but in the complexed form.

If u want something easy u can make a rpleca of the solar system. U can by those foam balls and spray paint them. Or u could do an experiment on two plants giving one sunlight and no light to the other. But still feed and water them.

well photosynthesis is a good way to start. the water from the roots are pulled by cohesion and then it leaves from the stroma in the plant leaves.

I did this as a kid...  grow your own crystal garden!\n\nhttp://chemistry.about.com/cs/growingcrystals/ht/charcoalgarden.htm\n\n\nhttp://chemistry.about.com/od/crystallography/

you could use alcohol extraction technique whereby you immerse the leaves in alcohol and let it sit for sometime until you see leaf extract. Or you can boil the leaves to get the extract this is called a decoction.

Do a hydroponic experiment.  it shows how the prospect of food shortages can be addressed.

I think let the Drosera grow naturally,with normal water.Please don't interfere with it's life too much.

We did this in a lab I studied in in college.  You have to grow the cells in a stationary location with light.  Often they will differentiate on their own, but you may heve to use a root promoting auxin to get the plantlets to take root.  Once they do, you transfer them to a suitable growing mix and voila! you have a plant.\n\nIncidentally, we pioneered some work growing Niotiana tabaccum cells in suspension by continually agigtating them.  They will not differentiate if you do this.
