Science Fair Project help?

Question

Ok so I'm thinking about doing a project on plants. First I'd take regular water and compare it with other types of water, like water that was previously boiled, water with food coloring and so on, and see its effect on the plant. I'd maybe like to do one with water some how altered by a chemical, but I don't know what type of chemical. Please help.

That's one of my problems, but I'm also unsure of this project as a whole, I mean will this actually work, will I see a difference in the plants growth? So maybe you can help me by expanding on my idea and giving me some tips and help or I hope you can refer me to a similar project I can do. Please help, thanks.

Answer 1

Well, the food coloring in the water will probably turn the plant a different color. Or at least I know it will work if you put a flower in water w/ food coloring. So, the project may work. You could use one plant with regular tap water, one with fluoride in the water , one with food coloring, one with water with alot of calcium in it, one with water with alot of rust, one with nasty water from a polluted pond or beach (something that you live around that you know is polluted) to see if any have an effect on growth. I'd imagine even if they didn't have much of a effect as long as you put alot of effort into the project and presentation the teacher will reward you with a good grade

Choose one kind of plant. A cactus does not require much water and its metabolism is too slow; so you need something that grows faster...I don't know, like a weed.
What parameters will you measure? Say rate of growth, color (use a digital camera a the same distance with the same lighting each time for comparison), hydration (measure this by taking the same diameter branches and see [again using the camera] at what angle they bend to a fold or even break.
Keep good records with your camera, date and time. Make sure the soil they grow in is the same: same depth, same amout of water, etc.
What kinds of water? Try adding peroxide 4% (try one set with one tablespoon to a liter concentration plus another with two tablespoons, the four, then eight), food coloring different colors, vinegar (an acid), baking soda (a base).
Water your weeds or other plants each day at the same time and the same ambient temperature (which you record at the time or watering). Also, measure the soil acidity each day--there are lots of ways to do this.
Put all your impressions and data in a notebook, make it readible and neat.
Good luck

I just lately judged a Jr. High technology reasonable. Some of the reasonable tasks had been quite ingenious. "They colour of cool"Can the colour of shingles have an impact on the temperature of a condo? "Night Writers" - How does lack sleep have an impact on your motor potential? They had persons keep up all night time giving them typing scan at more than a few aspects of the night time and after matters like ingesting a cup of espresso. "The unpopables" - Which company and/or taste of popcorn has fewer un popped kernels ? There had been such a lot of that had been high-quality. however those are those that I bear in mind because the exceptional

How about using the food groups as a guide? Try adding sugar to one, fats (oil) to another?

Household chemical would likely just kill the plant.
