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?|
|About this Project|
Looks like you are in the final stages of your projects
It’s great to see that teams from your school are wrapping up and posting conclusions. Enjoy the final stages of your project, and feel free to post any final comments or questions you have for your mentors.
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.
Please come back and visit the PlantingScience Research Gallery Archive anytime (Found under Community>Projects) to view this project in the future. You can search the Archive by key word, team name, topic, or school name.
Good bye for now.

Maybe next time I will just plant with soil instead of sand. Sand seems a lot complicated in my part.
That's great you are learning about how plants accumulate mass. Carbon from the carbon dioxide in the air is incorporated into the plant over time via photosynthesis and sugar storage!
Have you learned anything else? Have you come up with any conclusions for your experiment?
Yes, the water would help with the sand, definitely, because sand dries out faster than soil due to the particle size. What else would you do differently (remember what I said about varying too many things at once!).
I think we should try and water them more Frequently. While starting the project we did not water the plants until we were told by the teacher we should be watering them each every other day.
Okay, so we've figured out that you have varied two variables instead of just one in your experiment. You have varied soil type and light. If you were to do it again, what would you do differently?
Sorry, my response about the plants were confusing and I messed up. Unfortunaley we didn't do light and no light with the same variable (Soil).
Ok, thanks Lamah!
So, does everyone understand why it is difficult to figure out if light is the culprit or soil is the culprit for why the plant isn't growing?
So it sounds like you're having trouble figuring out why your plant in the light is not growing.
I'm still trying to visualize your experiment. Do you have 2 pots, 1 with sand and light and 1 with soil and no light, or do you have 4 pots--2 with sand, 1 with light and 1 without light, and 2 with soil, 1 with light and 1 without light?
If you only have the two pots this is a problem because you can't say whether the soil or the light is causing the difference in growth. From what we know about plants though, they should grow if given light, water, and nutrients. If they are not growing in the light and are in sand it might be that there isn't enough water for the seeds to germinate. Sand does not hold on to water very well because it has really big pore spaces between the sand particles.
Here's a video illustrating that:
Actually the plants that are receivieng light are not growing surprisingly, but the plants that are taking in light and water are not growing. They both have something different, the plants that are growing hase soil as the base and the ones that are not growing have sand as the bass. Maybe theres something there that's a problem with growing.
The plant that is growing without light is green at the tip and the rest of the stem is white. we have to stems right now and they are pretty long.
the plant in the dirt seems to be growing but the plant in the sand seems not to be growing
What do the plants look like that are growing without light? Are they green? Do they look the same as the plants growing in light?
I don't think this project relates back to plants. I'm not sure I may have to ask. Were only talking about the fish that migrate, because where going on a fieldtrip to a place where we are going to catch fish. Then we are going to have to study them.
Yes, we are currently doing a new experiment. We have to choose a type of fish that was given to us during watching a slide show. I have gotten the smelt fish, we now have to draw our fish and explain where it lives and where it migrates.
