can you help me with a scince prodjets
Of course! I would be happy to help you with your science project. What specific topic or area of science are you interested in working on for your project? Let me know how I can assist you further.
Problem: What are variables you can change to show carbon dioxide and oxygen being exchanged in photosynthesis?
Research: In order for photosynthesis to happen, a plant needs __________________________________________________________________________. (list the variables a plant needs)
Hypothesis: I think if I change the amount of sunlight a plant gets that _____________________________________ will happen.
Experiment: In the gizmo activity on this site, I did the following:
a. Changed the temperature
b. Changed the light intensity
c. Changed the amount of carbon dioxide
d. Record the data when changing the light wavelength. Every nm I wrote down the Co2 and 02 levels.
Conclusion: I found that when I changed _________________________ then _________________________ happened.
Problem: What variables can be changed to demonstrate the exchange of carbon dioxide and oxygen in photosynthesis?
Research: In order for photosynthesis to occur, a plant needs light, water, carbon dioxide, and chlorophyll.
Hypothesis: I think if I change the amount of sunlight a plant receives, then the rate of photosynthesis will either increase or decrease.
Experiment:
a. Change the temperature: Record the effects on the exchange of carbon dioxide and oxygen.
b. Change the light intensity: Record the effects on the exchange of carbon dioxide and oxygen.
c. Change the amount of carbon dioxide: Record the effects on the exchange of carbon dioxide and oxygen.
d. Record the data when changing the light wavelength: Record the levels of carbon dioxide and oxygen at different wavelengths.
Conclusion: I found that when I changed the amount of sunlight a plant receives, the rate of photosynthesis either increased or decreased, which affected the exchange of carbon dioxide and oxygen. Additionally, variations in temperature, light intensity, and carbon dioxide levels also had an impact on the exchange of these gases during photosynthesis.
