Science Buddies: "Ask an Expert"

To whom it may concern:
I'm yet another student analyzing data for my science fair project and I could use a hand. My project tests the effects of carbon dioxide on plant growth. I grew goldfish plants in jar "greenhouses". Using different of alkaseltzer tablets in water, I added different amounts of carbon dioxide to each greenhoues. I had 4 levels with 6 different trials per level. I measured the height of the plants over the next 6 weeks, measuring data once every 3 days. If you could advise me how to further analyze my project, it would be a big help to me. Thanks so much!

Hi!

I think youre starting off well, but here are some ideas. I hope they help. You could try measuring how many leaves or flowers grew. how long or tall the plant is, what color are the leaves, how thick are the stems, what is the width of the leaf? These are just some ideas. Also, to analyze your quantitave data make sure to put them in charts.

Hope this helps.

Thanks for the reply, but I'm curious. What type of statistical analysis should I do on my project, if any?
