i need a controll science experiment idea. it cold about anything just kep in mind that i am in the 6th gradeDoes anyone have a science project idea. - controlled experiment?
I did a controlled experiment when I was in 7th grade.
I tested how the temperature of water affected a fishes life span. So, i bought three fish, three bowls, some food, and other stuff. Then I would out cold, room temp, and hot water in the bowls...it was kind of a hard project, but it was fun.

Who owns and controls genetic information from the human genome project?
Francis Collins is the director and a pioneer of the project.
Who owns the human genome?
Every part of the genome sequenced by the Human Genome Project was made public immediately - in fact, new data on the genome is posted every 24 hours. It is true that private companies have filed thousands of patents on human genes over the past several years. We don't know how many such patents have been filed, whether the patents will be awarded or if they're enforceable. Most of the patent applications have not been acted upon, so we really don't know how much, if any, of the genome can be used freely for commercial purposes.

Could u suggest me a topic for my project.. i was thinking of face recognitionor thing like central control sy
common i'm looking for a good topic which can be done as my major project. Please do give me suggestions ..prefer to do something with the Computer and electronics together..Could u suggest me a topic for my project.. i was thinking of face recognitionor thing like central control sy
A great topic: how many al qaeda websites are up and running and how can they be viewed..Could u suggest me a topic for my project.. i was thinking of face recognitionor thing like central control sy
Thank you! I hope your project went well.

What is project controls?
Is it the same with project control? or Which is Which?What is project controls?
The criteria and the guidelines by which a project is to go forward. It's parameters.What is project controls?
Project controls are systems used to plan, schedule, budget and measure the performance of a project/ program.

What are the control group and experimental group in this project? (It's just a paragraph.)?
Francesco Redi wanted to find out if flies spontaneously arose (came alive) from rotting meat. Redi believed that flies hatched from eggs laid by other flies, other scientists believed that meat caused flies to come alive. He set up an experiment. In the experiment he had two jars. In both jars he put a piece of meat. Over one of the jars he places a net, which allowed only air to enter the jar. He waited several days and observed the jars. In the jar without netting, there were maggots (immature flies) on the meat. In the jar with the netting, there were maggots on the net but not on the meat.
I knew a few answers, but here are three I did not:
4.What was the control group?
5.What was the experimental group?
6.Was his hypothesis proved or disproved by the experiment?
10 Points!What are the control group and experimental group in this project? (It's just a paragraph.)?
The control group had nothing manipulated. The experimental group had an experimental treatment applied (the netting).
Redi's hypothesis that flies hatched from eggs laid by other flies is proved (this is not exactly how scientific hypotheses are tested, but for this assignment this should be ok).
The hypothesis should be:
H0: There is no difference in the number of flies hatching between the two treatments: rejected.
H1: There is a difference between the number of flies hatching between the two treatments (higher with no net): accepted.
Science advances by disproving hypotheses. In this case the alternate hypothesis (H1) should be accepted and subjected to further experimentation.What are the control group and experimental group in this project? (It's just a paragraph.)?
The control group would be the jar with no net, because it is known that there will be flies with no net. This would be the positive control.
The experimental group would be the jar with the net, because some scientists believe that you would get flies/maggots without access to flies.
His hypothesis was that flies hatched from eggs laid by other flies, therefore he was right because without access to flies there were no maggots.
This isn't very hard, are you being lazy? What grade is this in?
1. The control group: he placed a net over the jar.
2. The experimental group: he did not place a net over the jar.
3. His hypothesis was proved by the experiment.
This is a little tricky because the control group doesn't seem like it should be a control group, its the one without the net. The reason being that a control group keeps all variables constant within an experiment and what changes is a single variable, the independent variable. This might have been simpler if there had been a third jar covered with seran wrap, you can see that the variable of a barrier is whats being tested and the control is the plain ol jar being open to the air.
Experimental group then was the netted jar given that the variable being changed is having a barrier vs no barrier to the outside world.
Hypothesis proved-heres a sublte distinction that you may not think is important but is essential I assure you, and any biology teacher worth his HS diploma will feel this way too. The scientists hypothesis was SUPPORTED, not proven. The distinction is that in science things arent ever proven 100%, you simply have gained evidence in support of your hypothesis or not in support. In this case the evidence he has gathered supports his hypothesis that flies hatch from eggs laid by other flies.your cosmetics

How can initial and whole life costs be controlled on a project during the design stage?
The initial project cost remains an estimate, of increasing accuracy until project completion. The whole life cost estimate will increase in accuracy as the project develops. The accuracy of both of these estimates is dependant on the stability of the project scope and the effort invested in deriving the estimate.How can initial and whole life costs be controlled on a project during the design stage?
BY getting the design right, and building in contingency to the plan.

I need different variables on my science project plz help i need controlled independent and dependent?
i need heaps of help i have everything else i just need the variablesI need different variables on my science project plz help i need controlled independent and dependent?
You are looking at differences between five different kinds of seedling.
This is descriptive science, so you simply record what you see.
The control variable, which is the same thing as the independent variable, is which kind of seed it was.
The dependent variable is whatever you are observing about how they germinate and grow.
You don't really have a ';control'; group in this particular kind of experiment.
If you were comparing, say, whether fertilisers affect growth rate, your control group would be a group without any fertiliser.
For some kinds of experiment, e.g. about the effectiveness of medicines, it is very important to have a good control group, but I don't see how that applies in this case.
The real-world ';scientific method'; is more complicated and interesting than the ';one size fits all'; model they teach in school. See

well add more details like what the project is about and maybe we can help you...
ya i thought i would be able to help you but i have no idea. the answer below me seems right.
sorry... science isnt my thing
