| Explore | Plants need sunlight in order to go through photosynthesis. Without sunlight all plants would eventually die. |

| Research Question | How temperature affects cellular respiration |
| Predictions | the plant that is in the hottest temperature with release CO2 at a faster rate. |
| Experimental Design | Using three plants, we'll put one in room temperature, one in a warmer environment, and one in a colder environment. We'll measure how much carbon dioxide by the color of the BTB in the tube. All of the tubes will be covered in foil. We will measure the color over 24 hours and another time over... |
| Conclusion | The warmer a plant is, the faster cellular respiration will occur. To expand this experiment, we could do different types plants instead of only one type. |

Looks like you are in the final stages of your projects
It’s great to see that teams from your school are wrapping up and posting conclusions. Enjoy the final stages of your project, and feel free to post any final comments or questions you have for your mentors.
Farewell and Best Wishes
As this research project is now in the final stages of wrapping-up, we wish to thank everyone who participated in this inquiry; the students, mentors, teachers and others behind the scenes. We appreciate all of your efforts and contributions to this online learning community.
Scientific exploration is a process of discovery that can be fun! There are many unanswered questions about plants just waiting for new scientists to consider, investigate, and share.
Please come back and visit the PlantingScience Research Gallery Archive anytime (Found under Community>Projects) to view this project in the future. You can search the Archive by key word, team name, topic, or school name.
Good bye for now.
Warm regards,

Hi Everyone!
It looks like you've completed your experiment and written up some conclusions. That's great! I'm happy to see that you saw a strong difference in color change between your different temperatures. I don't know if you missed my questions last time, so I'll put them up here again:
Now that you have the results, why do you think your experiment turned out the way it did? What is causing cellular respiration to improve under increased temperatures? Do you think you could go even higher with the temperature and still have increases in respiration?
Let me know if you have any questions about your results or writing up your conclusion!

After 72 more hours all of the tubes have changed to a yellow color.
The hot one had more cellular respiration which turned it yellow, the cold on ehad less so it has gree pr tinted blue, the room temp one had some more warmth to it so it is a lighter green color. The hot one had more cellular respiration.
Awesome! It looks like your results came out the way that you expected them to. I'm glad to hear that you covered the tubes in foil to prevent photosynthesis from occurring. Now that you have the results, why do you think your experiment turned out the way it did? What is causing cellular respiration to improve under increased temperatures? Do you think you could go even higher with the temperature and still have increases in respiration?
The hypothesis is that the higher the temperature, the faster cellular respiration will occur. We have three test tubes and in each one we have a an alodea plant and BTB solution, which changes color depending on the levels CO2. Each tube is covered in foil and set at three different temperatures, hot(39 degrees C), cold(14 degrees C), and room temp(24 degrees C).
Sounds good! I think the temperatures you picked out will work well. Do you think there would be a point where the plants are too hot or too cold to perform cellular respiration?
Hi Jesse! Our group is wanting to conduct an experiment on whether temperature effects cellular respiration as it does with photosynthesis. What are your thoughts on this and what could we do to make this experiment better?
That's a very interesting question! Cellular respiration, much like photosynthesis, is essential for even the most basic plant functions. Do you have a hypothesis? How do you think respiration will change with temperature? And how do you plan on measuring respiration rate? That may be the hard part: separating photosynthesis from respiration. If you give me some ideas of what you wanted to do with the experiment, I'm happy to help out!
Hey everyone! I haven't heard from you guys in a while. How are things going on your project? Do you have any questions? Let me know!
Thanks for uploading your leaf disk assay results!
It seems like you all came to the conclusion that you need CO2 for the leaf disks to float. Is it the CO2 itself that makes the disks float, or something else? How does this experiment relate back to photosynthesis?
So we conducted an experiment yesterday on whether carbon dioxide effected photosynthesis and this was our result.

Awesome! What things do you like to grow in your garden? I grow peas, lettuce, and tomatoes. Here's what my little garden at my apartment complex looked like last year!
Im kaytlin, i dont know how to take care of plants.
Hey Kaytlin! Taking care of plants can be super easy with succulents, super hard with orchids, and everywhere in between! I personally like growing aloe vera because it is near impossible to kill.
Hi I'm Danielle and I don't know much about plants
Hi Danielle! That's OK, I knew pretty much nothing about plants before I went to college!
Hi Everyone!
Thanks for the introductions. A little about myself: I'm a graduate student in Biochemistry at the University of Nevada in Reno. My project is on trying to make crops that grow in the desert (Prickly pear, Agave, etc.) into biofuels. To do this, I do a lot of genetics, genome sequencing, DNA synthesis, and cloning.
When I'm not in class or in the lab, I spend my time doing just about anything outdoors in the Lake Tahoe area (hiking, mountain biking, backpacking, and camping). There's a lot of snow up there now, so I'm mostly at home. Hopefully it should all melt soon!
If you guys have any questions about science, college, or plants, feel free to ask me! In the meantime I have some questions for you:
What's your favorite plant?
What do you think makes a good scientist?
What do you think has more DNA: a human or a plant?
Don't worry about getting these right, just guess!
I look forward to working with all of you!
