|We know that leaves fall in fall, and that when the sun is facing away from the (Northern) Hemisphere, the leaves turn red because of less sunlight reaching us. We have discovered that cellular respiration and photosynthesis are linked, as they feed into each other, and that cellular respiration...
|Does being in a vacuum affect photosynthesis? We came up with this question by looking at available materials, and determining what we can actually test with said materials. This question fit what we knew by telling us that cellular respiration and photosynthesis are connected, but how connected...
|We predict that throughout this experiment, photosynthesis will not be able to occur without air. Cellular respiration is connected to photosynthesis and without one the other cannot occur.
|Does the amount of air affect photosynthesis? Hypothesis: If the amount of air is decreased, then photosynthesis cannot occur. IV: air pressure DV: acidity of BTB Constant: amount of light/water 1. cut the leaves into slivers 2. fill the flask full with correctly formulated BTB 3. put the...
|We have concluded that photosynthesis can still occur without air. There was enough carbon dioxide and oxygen that they could cancel each other out, and therefore no change in the results. The data we collected does not support our claim, as we discovered that photosynthesis did still occur in...

|Does being in a vacuum affect Photosynthesis? These student creatively planned an experiment to answer this question. I was impressed with thier experimental design and their intelligent interpretation of result. They made conclusions based on obtained data and proposed an improved approach to...
Thank you alot for taking time out of your day to check in with us! We appreciate all your feedback and comments on our biology work. We truly are grateful. Thank you!!!
Harper said it so well. Thank you all so much for your help and support throughout this unit! I hope we get to do something like this again.
Thank you to the scientists that helped us so much throughout this journey. Your feedback was truly mind changing, and I hope to one day get the pleasure of working with you all again.
Hi, Team — Great work conducting your experiment. A tricky thing to pull off, but I like how you guys went about it. And I'm glad to hear you reflecting on ways to improve the experiment.
We conducted our experiment, and we discovered that photosynthesis did actually occur in the flask. We also learned that the BTB did not actually change color because there was enough carbon dioxide and oxygen being produced for the cycle of cellular respiration and therefore photosynthesis to occur.
Hi, Team! There are many cues for deciduous trees to lose their leaves. Temperature and the number of daylight hours are among them. Can you guess how these two conditions change in the fall?
I would recommend not looking into "3. Does light color affect plant growth?". Unfortunately, it can be very tricky to isolate colors without special lights. Even color filters that only look like one color don't do a great job at removing all the other colors. And plants don't need much light of any color to be affected by it. But the other two experimental ideas sound really cool!
Ok Simon, here is what we got for research questions.
- Does temperature affect the rate of cellular respiration?
2. Does being in a vacuum affect photosynthesis?
3. Does light color affect plant growth?
What do you think/how can we improve on these?
Thank you for the details, Team! Let me know your thoughts on a research question. I'll be here the whole way!
All of the cups had 5-7 seeds in them. We believe that the cup without water will not germinate, this is because in lesson 4; building on knowledge from others, like our experiemt there were three dishes with seeds, one without water, one without light, and one with both light and water. The one without water was the only one that didn't even sprout. Our group has just started writing research questions for our expeiriment.
Hi, Team. Thank you for explaining the set up of your newest science experiment to me! Would you let me know which cup you think won't germinate, and why? If any of you think the same cup won't germinate, you can a work together to send me a one note voting for that cup. I also wonder: How many seeds you have in each cup?
Hi Simon, we are currently doing a project that tests in what conditions seeds will grow. We have 3 cups, the first with soil in a coffee filer and the seeds on the outside of the coffee filter and then we pooped water into it. This will test if seeds can grow without soil. The second had no water but all the other variables. And the third also had all the variables but light, it was put into a dark closet.
We all worked together in this new experiment and put the seeds outside of the soil and only watered two out of three cups. One is fully dry and in the sun, another is wet and in the sun, and lastly the final cup has water and is in a dark cabinet.
Hello! We are currently testing the conditions that seeds will sprout in. We have 3 cups: one that has access to light, and water, one that has access to no light with water, and one that has access to light with no water. All 3 cups have seeds that are separated from the soil by a coffee filter. Let's see what happens!
