Project Information
Many students think of the scientific method as a step-by-step process that all scientists follow in order. But real research is rarely so neat and tidy…it is really more of a research cycle or spiral because things you learn in one step can change your ideas about what you’ve already done or about next steps.
It is OK to change your thinking! We encourage you to go back and edit things you write in this section at any time as your ideas change. Just remember to explain your changes in your updates feed.

Explore | Plants need light to do photosythesis, they also need water adn carbon dioxide. When plants do photosythesis they release oxygen, they produce glucose that they use as food |
Research Question | How will light and dark enviroments affect the pH of water with elodea in it? |
Predictions | The dark environment will have a lower pH than the light environment |
Experimental Design | Our plan is to put the elodea in to 4 test tubes, two in the dark and two in the light. One will be wraped in foil and the other one will be put under a lamp. We will put phenol red into the test tube to see if the pH changes. Our control would be a test tube of water with no elodea in it. We will check it after 24 hours |
Conclusion | When the elodea is put into a dark environment it becomes more acidic because the plant is not doing phototsythesis and taking up the carbon dioxide, it is only releasing it. The carbon dioxide it the water makes it more acidic. When the elodea was put in the light it becomes less acidic because the elodea can do photosythesis and uses the carbon dioxide, this causes it to be more basic |

About this Project | I was impressed by this team answering all of the questions asked by the mentor! Their mentor always posted a new question pertaining to their research, and the team took to the time to reply to all questions! -- Devani Jolman, Liaison |
