|Explore||We know that plants grow and develop and they give off oxygen we also know that they feed organisms and they reproduce by seeds or spores. One of our group members has a garden who plants and water the plants there. She knows how to plant the seed by making a short hole about one inch and then...|
|Research Question||How does soil salinity effect seed germination?|
|Predictions||Our prediction is that plant #1 will grow the best because it contains no salt, #2 will grow a little worse than the #1 because it has 14.1 grams of salt, and lastly #3 will grow the worst because it has 28.3 grams of salt.|
|Experimental Design||The variables that we will test is how does soil salinity affect seed germination? The variables that we will measure and observe is how well the plant grows like how tall plant #2 and #3 is compared to plant #1 and how the plant #2 and #3 is compared to plant #1. The variables that we are...|
|Conclusion||My group of Libby, Hazel, Gianna, and I did an experiment to test the question, “How does soil salinity affect seed germination?” We tested how red and blue corn seeds react to different amounts of salt mixed into their soil. Our test pots were the blue seeds and our other pots were red seeds....|

Hi Steph! I had a great time doing the plant project with you! I thought that it was really fun. I wish you could do more projects with us! The group that has you for their project next is lucky to have you as their mentor. I hope you have a great summer and have fun with your dog! Bye!
You really helped us when our plants started turning brown. We had no clue what was happening. Our entire project would have failed if it weren't for you. You were a great mentor. Thank you!
Thanks, Steph! Thank you for helping us with our experiment and helping us with questions we had! Hope your summer is fun
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.
Thanks, Steph! It was really great talking to you. Good luck with your dog this summer. BYE!!!
These graphs look awesome!
Congrats on running your experiment! Before I leave you, I just wanted to say how proud I am of your progress and execution through the experiment. I could tell that you were all maybe a little frustrated that your salt-treated plants weren't growing as you had hoped, but that's often how science works. Things not working or not going according to plan is just a part of science. So, it's very important for you all to walk away from this NOT feeling like your project failed. It didn't at all! You learned that plants are much more sensitive to salt than you originally thought and that under ideal conditions plants grow pretty quickly. The beauty of science is that you still learn something valuable even when your projects aren't working perfectly.
I had such a great time working with you all! Good luck finishing the rest of the school year!
We're going to be starting our conclusions for our experiment soon. I wanted to say thank you for helping us with our experiment!
