We are doing a science project about how ph level will affect the color pigments in flowers. So we need a fast growing flower that will change color when we change the ph level. I heard about hydrangeas, but they take a long time to grow. Any other flowers?
I am doing a science project and I am curious if the type of water used affects the growth rate of plants.
I was buying some distilled water from walmart for a science project and my dad said that it was nothing but boiled water and that there was no difference between purified, distilled, and boiled water. so i was just wondering if there was any difference. references are preferable because i might put some of this information on the project itself. thank you 
I’m doing a science project on the question above, I’m using lemon, orange, and apple juice. Strangely, it was the cold temperature that changed the pH of apple juice more basic. Why? And does mold affect pH in any way? And how does time/temperature affect pH of acids?
Some resources and sites with information on the average pH of the juices would be helpful.
x_X I interpreted my data wrong, the one in the cooler temperature stayed the same and the warmer temperature ones became more acidic.
What method of purification do household Brita pitcher filters use? microporous filtration? chemical filtration? please answer and elaborate. for science project.
science project….need to filter bad water and make it clean enough to drink? so what do i use?
I need help with a Science project and one of the things is how is Fluoride added to drinking water?
Is there a store where you can have your water filtered for you through reverse osmosis? Or maybe I could go to a place where you can buy Reverse Osmosis filtered water…Its for a science project.
This is my son’s science project, but I don’t understand what the purpose is?
Its for a science project please make it quick!
Its for a science project so please reply quick!!
I’m doing a science project on water filters and i need to know the pH of it. if you can help, thanks ^^
I have to do an experiment for a science project on ‘if fertilized water is more effective than just regular tap water’. How can I make a fertilized water that will be effective? What should the water-to-fertilizer ratio be? Any other tips? Thanks.
I’m doing a science project for school and I need to know some ways in which these filters are used industrially or commercially to clean water, any help would be appreciated =).
what would be a good NATURAL water filter for my science project? because i can only think maybe sand….?
i want to get some fresh opinions!
