Info

Explore Work on this next!
What do we know about plants from our experiences outside of school? What have we discovered in class and background research? What questions about plants interest us?
Research Question Photosynthesis in different temperatures.
Predictions The leaves in the hot water might rise faster because theres more pressure and possibly more carbon.
Experimental Design Use spinach leaves in different temperatures of water with baking soda and use a lamp to see how quickly the leaves rise. We will use hot water, ice water, and room temperature water to measure the speed of photosynthesis at different temperatures.
Conclusion Our results are inconclusive because we were not able to take any data. None of the leaves floated to the surface. A possible explanation for our results could be that spinach leaves are not able to conduct photosynthesis in extreme temperatures. Our “room temperature” water sample was actually...

Hello Team! 

I just read your conclusion! Sorry you didn't have any data to collect. But no data is still data! So, I'm happy you were still able to draw some conclusions about why you got the result you did. I think you're on the right track, especially because you were able to get floating leaves in the room temperature cup! Excellent work!

Hello students!

My name is Cari and I'll be your mentor to help you through your project! I recently graduated with my Master's degree in science. I'm an invertebrate ecologists, meaning I study how bugs interact with their environment! I did my research in the Hawaiian rainforest! I'd be happy to tell you more if your interested. 

Other than ecology, I also love baseball, kayaking, and spending time with my wiener dog, copper!

I'm looking forward to working with you!

    Hi Cari! My name is Neda, and I was absent from school during our previous experiment, but I've since joined the group. I enjoy hiking, and like other members in the group, I also have a cat. I think environmental science is really interesting, and I'm really excited to work on this project!

    Hi Neda! Happy to have you in the group! Glad you enjoy environmental science and hiking! I do too! :)

Unfortunately we were not able to collect data from the lab. None of the spinach leaves floated so no photosynthesis occurred in any of the solutions.

I see now that you will be using water of different temperatures. I'll be interested to see how that works out! 

Are you using the plant leafing out as a measure of photosynthesis?

    Hi Cari, did you happen to see the document I linked on my recent post on the Updates Forum? There's a link to the Photosynthesis Lab protocol we did last week, which the students are modifying for this experiment. It's a version of the Spinach Leaf Disk Lab. Sorry the students weren't completely clear on their procedure, but hopefully that doc can provide some of the details you're looking for.

    I had not seen that! Thank you for bringing it to my attention. I was just hoping for more info on why they were predicting what they did.

Thanks for updating your info, team! I have questions already, however. I'm wondering how you're going to control the temperature of the water? Are you going to water it with hot or cold water? Or are you controlling heat from the outside using the lamp?

Also, why do you think the water temperature is important to the plant?

Hi, I'm Katy, I like to play volleyball and listen to music. I don't have a particular emotion towards science, but I do enjoy studying it. I am going to have to become more familiar, with chemistry because I want to be something in the medical field.

    Hi Katy! I used to play volleyball when I was in grade school too! What's your favorite kind of music?

    You're definitely going to need science if you want to be in the medical field! I find it really interesting learning how the human body works and reacts to things like medicine, so I hope you enjoy it too!

My name is lilly and I enjoy cats, my job, and video games. I am not really interested in science career-wise, but it is fun as a school course.

    Hi Lilly! I'm glad you enjoy science even if you don't want to pursue a career in it. It's an important subject to understand as it is constantly happening around us! What's your favorite video game? I don't play too many, but I really love Mario Kart!

    Hi Olivia! I'm happy to hear you're interested in environmental science! Do you preform in many plays/musical or do you prefer to watch them instead?
