|Photosynthesis is a process through which plants absorb sunlight, triggering a reaction that creates energy plants can use. It does this by converting CO2 to O2, using the carbon to create ATP. Questions: How do plant seeds know to grow in the correct direction? What are some things that cause...
|Will wood smoke affect the process of photosynthesis? We thought this was a great way to determine how forest fires could harm forest ecosystems. In addition to this, smog and pollutants could similarly block out light, reducing the rate of photosynthesis, and therefore reducing the rate of...
|If the plant is placed in a smoky environment, then photosynthesis will be inhibited. This is because smoke will block some of the light, reducing the rate of photosynthesis.
|1. Cut out 20 spinach disks 2. Fill two cups with 4cm of water, 2-4 drops of soap solution 3. Remove air from spinach disks by placing 10 into a syringe, and fill with 7 mL of water, pushing out excess air. Create a vacuum until all of the spinach disks sink to the bottom 4. Pour the spinach...
|Smoke inhibits the rate of photosynthesis. Light is necessary for photosynthesis to occur. When light hits the chlorophyll, it changes H20 into 02 gas. The smoke is preventing the light from reaching the chlorophyll, so 02 production decreases indicating that photosynthesis is also inhibited by...
|About this Project
|The members of this team came up with a very cool research question about how smoke affects plants' ability to photosynthesize. While this isn't a novel question, it showed to me that they were thinking about things that have real world consequences and something they were deeply interested in....
Wednesday we did our photosynthesis lab. The question we were trying to answer was "How does smoke/fire affect photosynthesis?" Our hypothesis was that smoke would decrease the rate of photosynthesis. Our reasoning was that smoke would decrease the concentration of light reaching the plant, decreasing the rate of photosynthesis. We tested this question by running a spinach disk lab. We had one control cup and another one that was exposed to fire. We placed some paper towels and grill pellets in a glass dish to produce smoke and placed this lit fire under a fish tank (to contain the smoke) with our cup of spinach disks. We then turned on the lights above both of our cups and timed the amount of time it took for the disks to float to the top. We found that the spinach disks exposed to smoke took longer to float to the top than the control group. This means that the presence of smoke inhibits photosynthesis. I will attempt to upload a rough drawing of what our lab setup looked like.
We ran two levels of this experiment, our first experiment had more smoke than the second experiment. The spinach disks exposed to more smoke took more time to rise to the top than the spinach disks exposed to less smoke, showing that the activity of photosynthesis likely has a direct correlation with the concentration of smoke.
My name is Sophia I enjoy reading and going on walks. I help my mom plant her garden every year but usually, the deer eat all of it. My love to grow is strawberries because they taste so much better when grown at home. My favorite subjects are Bio and Art. I don't know what career I want to do yet. Whats your favorite movie?
We are starting out the inquiry lab and wanted your thoughts on what we have so far. For a research question, we think something along the lines of "How does smoke change the effectivity of photosynthesis?" This question made me think about forest fires and how other plants are indirectly affected. Katelyn attached a picture of an idea we had for a setup but we don't know how to get the fire in the beaker, what are your thoughts?
Also, I would love to see the resources you talked about in your response to my introduction. Thank you
Hi I'm Katelyn.
My family recently started a garden but we haven't done much with it yet. I love plants and have around 16 that I've grown. My favorite subjects are biology and AP literature. I hope to become a marine biologist or do something else involving biology in the future. My favorite outdoor place would have to be when I went to Yellowstone over the summer. I loved learning about all the different hot springs and geysers.
What's your favorite national park or outdoor place?
Sunflowers are my favorite plants, I love how tall they are and how big the flower heads can get from such a such a small seed. We have done a couple of labs since the start of this project, one of these being the spinach disk lab. During this lab, we learned that CO2 is necessary for photosynthesis. We also did the experiment with elodea and phenol red. During this lab, we found that photosynthesis cannot occur without light and cellular respiration occurs in the dark. We also learned the Krebs cycle. This part is still a little confusing to me, but hopefully, I'll start to understand it better as we continue our investigation.
I'm Elise. I like to grow plants, both in my household and in my garden. We have a small apple orchard/vineyard, along with several other fruit and vegetable plants. I have recently been learning about grafting plants. My favorite subject is biology, and I especially like learning how DNA and genes play a role in everyday life. I'm not sure what my career goals are yet. What made you want to go into a scientific career?
My name is Jennifer and I am so excited to meet you and talk about science and life in general too! Something to know about me is that I have experience in biology, chemistry, and social science and I like to find the connections within and between different fields of science to help people better use science to solve environmental issues. I love trees and my favorite species is the eastern hemlock because it's always a cool calm place where they are in the forest. I also really like to watch scary movies and go on hikes.
I'm excited to help by posing questions and thoughts. But most importantly to answer questions about photosynthesis, plants (especially trees :D), what it is like being a scientist, or anything else you all are curious about.
What about you all? What is your favorite plant or outdoor place you like to go?
