Question Affects Different Water Types have on plant Growth

Hello, my name is Tatiana and I am 11 years old. This year I have to participate on the Science Fair at my new School and I have never done this before. I have chosen to do mine on the affects different water types have on plant growth, but how do I best complete the research and record its results. I was thinking of using tap water, spring water and rain water and using the same pots and same soil and planting three bean seeds for each water type. Keeping them in the same exact environment so they are exposed to the same things and water them every other day and record the results to determine if there is in fact a difference in the growth caused by the water type. Any ideas or thoughts on this? Do I also need to do research on the different water types, what is in them and why their affect is different? Or do I simply record the results and do my project based on my findings? Help!!!

You need to state a hypothesis.

Like: I belive that under controlled conditions, the Rain water will be most effective on the plants overall growth.


Then just record what you see every day or so.

But I would use something else besided Rain water.... becuase what do you do if it is not raining?

Mabey even H2O2 {Hydrogen Peroxide 3%-5%, what you proably have in your cabinet}, just to see if it can sustain life
Overall this is a good idea, and can be a good project

Default Excellent comments from Archenemy!

This is what I call a good discussion on science/the scientific method !

Thanks for making my day!

Default Different conditions for plant growth

You can try to increase the acidity (by adding different amounts of vinegar), or increase the sugar content of the water (by adding different amounts of sugar into the water). If you do the sugar water experiment though, you will have to make sure that there are no ant problems at your home!

I've grown seedlings using a *clear* plastic cup, putting wet paper towel on the inside of the cup. (for your experiment, you would soak the paper towel with your different solutions) Then put the seed in between the paper towel and the cup. That way you can see the seedling grow over time. You can measure growth by measuring the length of the root with a ruler (outside the cup, without having to disturb the seedling), and also after how many days the leaves appear. Having more than one seed for each condition is good, as it is more scientifically accurate to average how fast the seedlings are growing.

Everyday, you can wet the paper towel with a fixed amount of the appropriate solution.

I hope that helps!

Default seeds and plants

I did something similar too in my elementary school days. Brings back memories.

Default elementary school science project

Actually, I've also tried something similar - way back in elementary school too. One of the easier / simpler projects - only, I can't remember what I was trying to prove/discover.

Hi, Biogradstudent! Im interested in trying out this experiment - how may seeds should I use? 5, 10, 20, 100?

Default Averaging your results

Biogradstudent is absolutely correct. To avoid measurement errors, you should average out your results. You probably should work with at least 5 seeds per test.

Default 5 seeds sounds just right

Thanks - so that means if I do 3 tests with different levels of sugar content in the water, for each test, I should use 5 seeds right?
