A member of our group has done some gardening work, and has previously worked with Wisconsin Fast Plants in middle school. We have discovered from research that Wisconsin Fast Plants...|
|Research Question||Research Question: Does vortexing of Wisconsin Fast Plant seeds affect their growth rates? We are studying/experimenting to see if the growth of Wisconsin fast plants are affected by a "vortex" treatment performed on the seeds prior to planting. Our vortex treatment consists of using a vortex...|
|Predictions||Our hypothesis is that if Wisconsin fast plant seeds were vortexed with sand, then those seeds would grow faster than if they had been vortexed with only other seeds, which would grow faster than seeds that had not been vortexed at all; however it is possible that the seeds may grow at different...|
|Experimental Design||Our plan is to record information on when the fast plants appear above the soil. Three groups of 12 seeds, one group previously vortexed, another group vortexed with sand, and another group with no vortex treatment, were planted. One of each group was planted in each of 12 film canister. A...|
|Conclusion||The average time it took for the seeds to sprout did not vary greatly between the different groups, and the range of the sprouting times was slightly less than three and a half hours. Furthermore, 4.5 seeds from the control, 5.5 from the seed vortex, and 2 from the sand vortex group sprouted...|
Thank you for the thoughtful notes! I really enjoyed this experience and mentoring such a great group of engaged young scientists! I also am very impressed with your final report. Good luck with all of your future endeavors.
Happy Thanksgiving Ms. ArchMiller! (http://dl.glitter-graphics.com/pub/3525/3525861zqw6rbfja5.gif)
So it's Thanksgiving today, and we've also finally finished our entire report:) Today's the day when we're supposed to give thanks to everything we are thankful for. I am extremely thankful for having you as our mentor along the way, and I truly appreciate the time and thought you put into our experiment. Even though this may seem trivial in the grand scheme of things, it's really the little things that make us happy:) We are so fortunate to have gotten such a helpful mentor.
You are such an inspiration, and I could only dream to do the amazing things you have accomplished. I wish you the best with your family and career. Hope you have a great Thanksgiving!
Couldn't thank you enough,
Hey Ms. ArchMiller,
I guess the end of this project is our goodbye, but before parting ways, I want to tell you how grateful we all are for your assistance (fitting, isn't it, since Thanksgiving is tomorrow?). Thanks for being the greatest mentor we could ask for! You were responsible, reliable, and reassuring the whole time through, and even though our plants all withered and died, I know that we learned invaluable tactics and gained incredible experiences along every step of the way. With the support of our team members, and of course our amazing mentor, my experience with PlantingScience has been an unforgettable journey. We appreciate all the time and effort that you have devoted to our project, and we're very thankful for you. :)
All the best,
Hi Ms. Archmiller,
We uploaded our final report for this experiment in the project files, titled HTHS_Team16_Report.
On behalf of our team, thank you so much for being the best mentor, and helping us along the way. :)
At this point, we are just looking at sprouting times for the plant; so when the plant can first be seen above the soil, we record the time.
Our plants did not develop properly (two potential reasons are lack of proper lighting, low temperatures), and none of them even have true leaves yet, despite the fact that some are several centimeters tall. In addition, it seems that quite a few of them did not even sprout, and some died quite early into their life span.
Hi Ms. Archmiller,
Currently, to give you an update, our group is working on our lab report for this experiment. Hopefully we can communicate the data to you soon. Do you think measuring the data in hours would be an appropriate measurement?
Are there video editing programs to draw a line across the video screen where the desired height above the soil (represented by the tick marks on the skewers) would be? That way, it would be much easier to see when the plants reached that height. Or are some soil levels higher/lower than others? I don't really remember if we tried to make all soil levels exactly the same...
Also, this response is a little late, so has data been collected yet or are we still looking for ways to measure growth?
There are programs available to record what's happening on a screen as a video, so maybe you could upload all the images and record yourself scrolling through them.
Also, if it's a little hard to see the exact moment the plant reached a certain height, maybe we could start from a place where it's obvious where the plant is and go back frame by frame, keeping your eyes on the plant, until you see the single frame where it reached x centimeters.
I'll work on uploading the pictures somewhere... it's probably a few hundred pictures and I just scrolled through them to simulate a video. We should meet up during school and look at the pictures, and I'll try to upload them for Ms. Archmiller.
Thanks for keeping me up-to-date on everything. Couple thoughts:
- If I recall the original hypothesis, you all expected that by vortexing the plants, you may help break down the seed coat, thus allowing faster water uptake and germination relative to the control plants that had intact seed coats. To test that hypothesis, I personally think that you should try and use the time-lapse cameras to tell when each plant germinated. Or in the case of time-lapse, when the first visible sign of germination was present.
- In addition to "when you first detected germination" you could also include a rate of growth (for example, time to grow 3 cm) as an additional dependent variable, but I am most interested in knowing if seed coat destruction affected germination.
- Also, if you test for germination as your main dependent variable, you don't have to worry about the plant that fell over or redoing the experiment again.
- First step will be to record your data. Secondly, you can calculate average and standard deviation of your dependent variables for each treatment group, then you can start to try and make conclusions.
Hi all -
Today, several of us checked on the plants again. Most of them were lopsided/dying, and Mr. Roche told us that it was most likely due to our weak light source. I took out the SD card and watched the time lapse of our plants. I uploaded a video of what the time lapse looks like. Ms. Archmiller - do you think the video is clear enough to collect data for when the seeds first germinated/sprouted? The time for the time lapse camera starts on the wrong day/year (it says something along the lines of November 2011), but I can still see the seeds germinating. It is a bit grainy and unclear, though. What do you guys think?
When should we plan to check the time lapse camera? I'm sure that its battery died/SD card was used up by now, but I don't really know the procedure for checking the card. We could stop in the research lab and bring the card to the nearby CIM lab and check it there. What do you guys think?
