|Explore||Plants need water to survive so they will inherently suck up water in a cup.|
|Research Question||How far can a piece of celery bend using salt and water?|
|Predictions||The celery will bend a lot more.|
|Experimental Design||We will start our experiment by getting a cup of 300 ml of water in four cups. In the first cup we will put 30 g of salt. In the second cup we will put 50g of salt. In the third cup we will put 75g of salt. In the last cup we will put no salt, this will be our control group. We will then cut our...|
|Conclusion||We found that salt was responsible for the shrinking, shriveling, and bending of the pieces of celery. The more salt that we put into the solution, the more that the celery was affected. In the control group though, the celery sucked up so much water that it began to expand too much and split in...|
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.
You have until Friday, November 19, 2021, for final posts to be added, so please be sure to thank your fellow teammates!
Hi Brylen, Malik and Evan,
By so far one thing which is much clear by your experiments which you should point out as a result of your experiments. You can define the relationship between the shriveling, bending of celery with the concentration of salts.
Second, Testing the hypothesis, could you please test your hypothesis with the results obtained from your experiments?
Me, Brylen, and Evan put each group on a paper towel and the more salt meant the more bendy the celery ended up. The control group celery sticks were not bendy at all.
We found out that the more salt that was in the solution, the more shriveled, bendable, and smaller the pieces of celery became. In the control group we found that the celery absorbed the water and bent naturally, expanded, and became extremely hard.

Welcome to your PlantingScience project page!
Welcome to this community of plant researchers. As your team plans and conducts your own research project, you will be mentored by a scientist. The mentor's role is to encourage and guide you through the process of scientific discovery. The more you share your ideas and research information online, the more your mentor can help. You can also find out more about your mentor. What is their research about? Why did they go into science? What do they like to do when they are not working?
You may also hear from this classroom’s assigned scientist liaison. Liaisons work with several mentors and help make sure the conversations are going strong. They may also offer some extra advice or encouragement.
Two resources can help you get started:
Best wishes as you start this scientific journey. We are all pleased to share this experience with you. Have fun!
