We do not do your homework for you. Although it might take more effort to do the work on your own, you will profit more from your effort. We will be happy to evaluate your work though.
For a start, since this is not my area of expertise, I searched Google under the key words "greenhouse gases for kids" to get these possible sources:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.

2. What are the greenhouse gases? Which one is the biggest concern?
Other greenhouse gases include CFC's, SF6, and N2O and H2O.
Nitrous oxide is 310 times more powerful than carbon dioxide in trapping the heat.
Carbon Dioxide is the most dangerous greenhouse gas.
Well, the one that causes most global warming is actually water vapor, but we can't do anything about that. That has stayed constant for thousands of years. The ones we can do something about are:
Carbon dioxide (causes up to 26% of greenhouse warming)
Methane (up to 9%)
Ozone (up to 7%)
Methane is 20 times more powerful than carbon dioxide, but there is not so much of it, so probably carbon dioxide is the most dangerous.
3.What are scientists doing to collect data?
They do experiments and research.
