A literature review is essentially a summary of what you have read as background before you did your science experiment. You can quote or paraphrase information that is relevant to your experiment. It is important to cite where you got your ideas from. Here is a website that explains this part of th...

Here are two sites that explain how to measure oxygen content in the air: https://www.sciencebuddies.org/mentoring/project_ideas/Weather_p004.shtml http://www.pbs.org/wgbh/nova/teachers/activities/2506_everest.html You could probably test the amount of oxygen content in the air before you add plants...

This website addresses the first two conditions for optimal growth for soil bacteria: http://www.sigmaaldrich.com/Area_of_Interest/Analytical__Chromatography/Microbiology/Theory/Introduction.html The "optimum growth temperature ranges between 25°C and 40°C." The optimum pH for "most...

The purpose is the problem you are solving in your project. On a display board, it can be stated in the background information section or the introduction. This is an example of a purpose statement "To find out how table salt affects the boiling temperature of water." (http://www.isd77.k12...

I'm not sure if this is what you're looking for, but I read that most horizontal axis wind turbines "have a gearbox...which turns the slow rotation of the blades into a quicker rotation that is more suitable for generating electricity" and vertical axis wind turbines have "lower energ...

There was a previous discusssion about this topic on the forum:

https://www.sciencebuddies.org/mentorin ... php?p=4389&

this should give you a starting point for your research

I'm not sure what your question is, but here is some background information you could use in the introduction of your paper: http://creatures.ifas.ufl.edu/nematode/red_ring_nematode.htm http://nematode.unl.edu/pest1.htm http://ucdnema.ucdavis.edu/imagemap/nemmap/ent156html/nemas/rhadinaphelenchuscoc...

A google search brings up a lot of sites for "red ring nematode"

Here are some comprehensive sites:

To find a mentor (and a lab), try contacting research scientists at a local university. In your case, try looking up scientists that are doing work related to your project (i.e. look for key words like plastics, chemistry, polymers, etc.) Send them e-mails (don't worry if some don't reply back, they...

Your project may fall under the psychology category, but you can ask your teacher this question.

You can use iodine instead of Lugol's solution (potassium iodide).

This webpage has a procedure for using iodine to test for the presence of starch:

I don't believe there is something called "egar" to prepare petri dishes. However, "agar" is used to grow bacteria on petri plates. Dehydrated nutrient agar is dissolved in water to make a solution and that solution is poured into sterile petri plates (this is just a brief explan...

The title does not have to be a question.
If you are making a display board, the title should be "attention-grabbing."

You may be able to buy this plant at a local nursery.

If you have trouble trying to find wall cress, mustard seeds should be fairly easy to buy (and they would fit the criteria of the plants you are using in your project).

Arabidopsis thaliana (common name: Wall cress) is a fast growing plant.

Mustard seeds are also fast growing.

There are 2 indicators for vitamin C; starch-iodine and indophenol.

I don't think you can buy either indicator at a CVS; but you can make it.

Here is a link for the preparation of Vitamin C indicators.

Good Luck.
