|Explore||All seeds contain a diploid embryo and a food supply. The diploid embryo contains the root, the stem, and the leaf, which are called cotyledons. Most of the seeds have a shell that is called a seed coat. Dicots (plants with two cotyledons) store their energy reserves in their leaves. Monocots...|
|Research Question||How does the type of liquid affect the germination of the seed?|
|Predictions||If we change the liquid, then water will do the best while the alcohol in the hand sanitizer will kill the seed. This is because the water is the thing that a plant needs to grow and the alcohol in the hand sanitizer will kill the seed.|
|Experimental Design||Control: Amount of light, water, and temperature of water and area Independent Variable: Type of liquid Dependent Variable: Growth of plant at the end of a week. 1. Collect materials. Materials: 50 buckwheat seeds, 5 paper towels, 5 plastic bags, beef broth, carbonated water, water, hand...|
|Conclusion||Claim: Watering seeds with Carbonated water makes them grow better. Evidence: Carbonated water had a average measurement of 6.9 centimeters. Hand Sanitizer grew the worst, heck it didn’t even grow at all. Apple juice was second worse with beef broth being second best. Water didn’t have a...|
|About this Project|
Dylan couldn’t measure the seed because they were all tangled. This soiled the experiment because without a proper measurement from Water we can't really solve the question. In the future we can spread the seeds farther from each other so there is little chance of them getting tangled,
Tim, apple juice, saw many types of mold in his bag of seeds. This might have been because the sugar in the juice had fermented, or because he forgot to wash his hands before handling the seeds. This killed or stunted the growth of a few of the seeds and left our findings maybe a bit wrong. To prevent this in the future we can keep human contact with seeds to a minimum, to reduce the amount of bacteria that gets on the seed.
I didn’t water my seeds every day, for I saw that my bag was still wet even after a few days, maybe my measurements of 5 ml were accidentally 5 cl, but to make sure this doesn’t happen next time, we can double check our measurements and measurement devices respectively.
I am somewhat confident in this investigation because we conducted ten trials and used scientific principles and concepts, but the attempts of error we considered were not the same as the errors we faced. We thought we had accounted for every problem, but we didn’t consider the idea of mold getting into the seed containment bags. If we could have prevented this, our results might have been more correct. We used ten seeds, just incase a few died. At least 1 died in each, this was expected but we didn’t know that mold could spread between seeds so fast. We tried to clean out the mold and Tim changed the apple juice paper towels daily, but the mold still spread and plant lives were still lost.
Hm, I would say to think about how you could have measured the control roots, or another way of measuring the roots where it would not matter if they were tangled. In some of the graphs "length of the seed" is a little confusing - is it just length of the roots? Maybe mass (weight) of the seedling could have been measured, that way the tangling would not have mattered? Really interesting results here, great work everyone!
These graphs look exciting! Do you have total growth for the controls as well? I cannot read the full conclusions...
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.
