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||What do we want to test or study? How did we come up with the question(s). How does the question fit what we know about the topic?|
|Predictions||What are the possible outcomes of our study given the variables we are working with? What is our explanation for why and how we think this will happen?|
|Experimental Design||What is our plan? Be sure to include enough detail that another group can replicate our experiment. What variables will we test? What variables will we measure and observe? What variables will we keep constant? How will we record our data?|
|Conclusion||What claim can we make from our experiment? What are possible explanations for our results? How do the data we collected and our reasoning with scientific ideas support our claim? What future experiments could be done to expand on the results of this experiment?|
It looks like the problem is resolved and everything should be back to normal. Please feel free to resume posting, and do let us know if you experience any issues posting to your projects.
We are aware of some technical issues with the platform, leading to an issue with posting to project pages and issues with users' dashboards. We are working diligently with our developer to resolve them as quickly as possible. Please be patient and keep checking your projects so you can post your hellos, updates, reports, thank-yous, and goodbyes.
Farewell and Best Wishes
As this research project is now in the final stages of wrapping-up, we wish to thank everyone who participated in this inquiry; the students, mentors, teachers and others behind the scenes. We appreciate all of your efforts and contributions to this online learning community.
Scientific exploration is a process of discovery that can be fun! There are many unanswered questions about plants just waiting for new scientists to consider, investigate, and share.
After the end of the session, we will be updating the platform and archiving groups and projects, after which time new updates/posts will not be able to be added to projects or groups. You have until Tuesday, April 25, 2021, to post ALL of your updates, comments, and goodbyes. Please come back and visit the PlantingScience Project Gallery anytime to view this project in the future. You can search the Gallery by keyword, team name, topic, or school name.
Good bye for now.
The PlantingScience Team
In your data table, are the measurements growth since the last time it was measured or the total length of the sprouts?
Also, what were the condition of the stems and leaves as the experiment went on? Sometimes if a plant is not getting enough light it will grow fast and turn a whiteish color as it uses up it's stored energy.
Over the course of the experiment we learned that the beans getting germinated under colored light did better than the ones under the plain sunlight. Somethings that were experimental errors we had were that some Petri dishes and peas got a bit dry at times and so we could have watered a bit more regularly. We also could have labeled a bit more thoroughly just in case. Thank you for all of you help over the course of this experiment!
We have concluded the experiment.
We learned that the green light is the best, then blue, then red, and then normal light. Before, I thought that the normal light would do the best, but actually, it did the worse. The other part about the order of the colored light was all correct.
If I would have done it again, I would try to log more days. There were many days we missed. I will post the hypothesis and the graph.
Thank you so much for your guidance. You were very helpful.
We learned so much from this experiment. Including the fact that seeds germinate faster with different colored light wavelengths! Thank you so much for your help. We couldn't have done it without you! One thing that I would do differently next time is to do more trials so we can get totally accurate information.
