| Explore | They perform both photosynthesis and cellular respiration to make energy. In this class we have discovered that the higher the amount of CO2 in the plants environment the rate of photosynthesis increases. One question that interests us is what kind of light will have the highest rate of... |
|---|---|
| Research Question | We want to test what kind of (artificial) light increases the rate of photosynthesis the most. This question fits what we know about the topic because plants need light to preform photosynthesis. |
| Predictions | Honestly not really sure, we predict that one of the kinds of light will preform photosynthesis the best. We think this will happen because the lights emit different types of light waves. |
| Experimental Design | Our plan is to follow the spinach leaf disk lab procedure for the baking soda cup and make 6 of them. We will then place one cup under the sunlight, one cup in the dark, one cup under fluorescent light, one cup under incandescent light (150 watt), one cup under 200 watt light, and one cup under... |
| Conclusion | From our experiment, we can make the claim that the 200 Watt light bulb was most effective of the artificial light in regards to rates of photosynthesis in spinach leaves. Although the evidence shows that the time at which all the leaf disks float is the same for both 200 and 250 Watt light... |

Thanks for your feedback! As a group we decided to change our question to, "How does artificial light compare to that of sunlight?" We were wondering if you think a heat lamp would be an ok dependent variable in our experiment or would the change in temperature cause us to get weird results?
Great, on the change in the question. I think that the revised question will enable you to match your methods to your question much more closely. If you wanted to incorporate a heat lamp you have a couple of options. You could A) increase the complexity of the experiment by comparing the different types of light with and without the heat lamp. So that would look like:
Sunlight
Sunlight + heat lamp
Artificial light type 1
Artificial light type 1 + heat lamp
and so on.
Or B) you could add the heat lamp to all treatments. In a paper, you would need to discuss that you could not truly disentangle the effects of the heat and the light, right? But, you would be treating all of your experimental units the same.
Hi, I uploaded some feedback regarding your experimental design. Overall, I think it is off to a great start! Please let me know if you have questions.
Hi, I'm Rachel and I will be your Planting Science mentor! I currently work as a Research Ecologist postdoc at the National Sedimentation Laboratory for the Agricultural Research Service(ARS) of USDA. ARS is the research arm of the USDA. Currently, I am working on ways to reduce nitrogen export from agricultural fields to downstream freshwater ecosystems. Before that, I worked in Maryland researching nutrient use in Amazon forest regeneration. I earned my Ph.D. in Interdisciplinary Ecology from the University of Florida in 2015 where I did research on Florida spring ecosystems. I'm excited to join you on the project!
Hi! My name is Amber and I am a junior. I like running and gardening. I really want to go scuba diving!! I find marine biology super interesting and I would love to do something with that and in relation to engineering
Hi, my name is Ginger. I am a senior in high school currently taking AP Environmental Science. Some of my hobbies include hiking, running, and spending time with family and friends. I am interested in environmental science because of how the processes in our environment connect to ethics, politics, and history. I am looking forward to working with all of you!
Hi, my name is Maya. I am a senior in high school, I took this class because I care about our environment and want to learn more about what I can do to help protect it.
Hello! My name is Sarah and I am a senior in high school.
In my free time, I like writing, reading, and playing marimba.
Although science isn't something I am interested in as a career, I am excited to learn about the environment we live in and how our actions affect and change it.
