| Hi, I am an 8th grader and want to do my science fair 
project using a cloud chamber. I got a plan to buidl a cloud chamber but have 
had trouble getting it to work. I think because it is not air tight, but I'm 
working on that. What do you recommend I can do showing cause and 
effect experiment. I need one independent variable and one dependent variable. I 
was going to do the following but, I have had a hard time getting the chamber to 
work. Is there something I can do in my home that is easier. I need quanative 
data.  Thanks  Tom Dadourian |
