Info

Explore for our project we are going to be testing if seeds placed inside of a plastic bag with cotton balls inside them can grow using liquids other than water which would include, milk, coffee, seltzer, and gatorade. everyone who is running tests will test two bags with seeds in them, one will be...
Research Question Will the bean sprouts be able to grow in varied solutions other than water? If so are there changes in height based on different solutions (independent variable) that they are growing from such as energy drink(containing caffeine), water, fruit juice, and sports drink(containing ion)? Other...
Predictions Hypothesis If the seeds are placed in liquid other than water then the seeds will not be able to germinate. Null Hypothesis If the seeds are placed in liquid other than water then the seeds will have no effect.
Experimental Design 1. Prepare 2 plastic bags, one for water (control variable), and another for different liquids (independent variable). 2. Place 1 or 2 seeds into each cotton ball. 3. Make cotton balls wet with water and liquids. 4. Seal the top of the plastic bags. 5. Take the bags under the sunlight or UV...
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

Youbin, Giana, Bella, and Izzy made excellent observations about their seeds. They persevered even when their methods didn't work out quite as they expected, and they clearly communicated their thoughts and questions to me as a mentor. I'm proud of them for really engaging with science as a...

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.

Warm regards,

The PlantingScience Team

Dear Ms. Dawson, 

Thank you for your time and support through this plant experiment. I hope you have a nice day!

    Thank you for sharing the process with me, Youbin! I hope you have a great rest of term.

Hi Hilary, 

I wanted to thank you so much for helping me throughout this process and I just want to say that I am done with my experiment and I really appreciate all the pointers and helpful questions you asked and presented.

    said

    It has been my pleasure, Izzy! Thanks for sharing the process with me and good luck with the rest of your coursework.

Izzy, I'm sorry to hear that your seeds have gone moldy. Could you remind me which liquid treatment they had? Is anyone else seeing mold?

Youbin, you mentioned a possible white mold. Seeds often have very fine roots to help them grow. Do you think you're seeing mold or fine root hairs? Since they're growing in milk, either one seems quite possible.

    said

    My liquid that I used was red Gatorade, I don't think anyone else has the same mold that I had. Could this happen because of the sugars in the gatorade?

    Hilary Rose Dawson
    said

    That would be my hypothesis! Do any of the other liquids have sugar? How are those seeds doing?

For our 6th day of the experiment, my reddish seed that was planted in the water at about 25C room temperature, the plant became about 12 cm long. The sprouts are thin and white. At the end of the sprout, there are two leaves coming up and below there is a branch of another sprout with two leaves. In the bag where the seeds are planted on the cotton with the water spilled, the bag is blown up with air. However, in the ziploc bag with the seeds are planted on the cotton with milk spilled, there isn't much air to show the changes in the Ziploc bag compared to the beginning of the lab. It has slightly more air than the first day of the experiment. But the reddish seeds are still growing. They look healthier than the ones that are grown in water as they have thicker leaves coming straight out from the seeds. On the first day of this experiment, they both had sprouts coming out of seed first. However, in the milk one, the sprout turned white and stopped growing much and start to have white furs with having the bottom of the sprout with leaves. It looks like they are growing from opposite places now.

Today, which is the 6 day of collecting data from the experiment, I collect the data of the appearance of plants and the length of sprouts by not opening the plastic bags. I can find that there are more mold in the Group A cotton balls than yesterday. Also some leaves fall out from the plants, and one whole plant also falls out from the cotton balls. I think I handle the plants in the wrong way. The color of the plants were light green and some yellow and there are some brown dots on the surface of the leaves. 

Group A : 1.8cm/ 1.6cm

Group B : 3.5cm/ 1.5cm

For day 6, the water sprouts they don't look like they have changed much, they are the same length. There seems to be a liquid I believe to be water on the leaves. One of the sprouts in this bag is short and has brown dots and a yellow spot. I think this sprout may die. Two sprouts in the seltzer water bag are 5cm and and 6cm long while the other two in this bag haven't grown. There looks to be the same liquid on the leaves in this bag. One of the short ones is like a white yellowish color. Both the smaller ones haven't had there seeds/shell fall off the leaves yet.

Today, which is the 5 day of collecting data of the experiment, I collect the data of the length of sprouts and appearance of seeds by not opening the plastic bags. Overall, the plants grow more than 2 days before. 3 out of 4 plants grow but actually these grow really a bit more than before. And the other one grows really well, it grows 2cm. Also in group A, there is mold in the cotton balls.

Group A : 1.5cm/ 1cm

Group B : 3cm/ 1.5cm

For our day 5 observations on seeds, the seeds grew a lot over the weekend. The seeds that are planted in water has grown abt 8 tp 9 centimeters long sprout with the two leaves at the end. The ziploc bag that was flat in the beginning of the experiment, but now it is fulled with air in the bag. On the other hand, the seeds that are planted in milk are thicker and smaller than the ones grown in the water with less air produced. Also, in the one planted in milk, for last past few days there was only 2 to 3 cm white root with the white mold fur, but today, at the bottom of the sprouts on the top of the seed, there are thick leaves grown.

Hi everyone,

My name is Asawari and I am the liasion for your group who will help your mentor and your teacher! I am a PhD student at the University of Toronto, Canada working on evolution of parasitic plants ie these supercool plants that cannot photosynthesize themselves so they take help from other plants! 
I will check on the updates in the group every few days and try to respond as soon as possible (in case mentor is not able to) so that your group can maximise the learning from this session.
Hope for a great session and good luck with your experiments!
