| Explore | plants start as seeds they need light water and food |
|---|---|
| Research Question | how does the strength of light affect how fast the speed of germination is? |
| Predictions | if we increase the amount of light the seed would receive the seed will grow at a faster rate. |
| Experimental Design | step 1: in 8 different Petri dishes place paper towel step 2: in each petri dish put 5 mustard seeds and squirt 25 ml of water each step 3: place petri dish under box with the 40 watts light bulb step 4: place petri dish under box with the 60 watts light bulb step 5: place petri dish under... |
| Conclusion | If we change the temperature of the seeds environment to over 100 degrees, then our seeds will not germinate or grow. This is because the temperatures are too extreme for the seeds to begin their germination process. We observed that all of the seeds under the 100watt lightbulb did not... |
| About this Project |
The Water Kingz ran into a situation where none of their seeds sprouted. The reason was unrelated to their question but happened due to their experimental design. This team persevered through what felt like ¨no data¨. Working with their mentor the learned that no growth is still data and know... |

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. 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
Excellent work thinking through possible sources of error, and what you would change!
How confident are you in your results? (Use a statement from the confidence chart and support your statement using examples from the bullet points.)
I am not confident at all in our results because I conducted less than 3 trials. Additionally, we did not consider all of the possible sources of error (such as the temperature). Furthermore, we did not maintain all of our controls such as the temperature, and amount of water, and during the weekend they did not even all receive their assigned light wattage.
What are three sources of error during your investigation and how did they affect your results?

Source of Error |
How it could have affected your results |
|
After the first day, we did not have a consistent amount of water we were giving each petri dish. |
This could have caused different Petri dishes to have different results because they were being given a different amount of resources so ones receiving more water could have done exceptionally well or rotted. |
|
On the day we planted them it was a half-day and thus they did not get very much water. |
This caused them to be wet at first and swell. However, once the water dried up they shriveled back up. This could have caused the seeds to be confused if the conditions were right for them to grow. |
|
After the weekend when we checked on our sees we found that the 75watt and 100-watt Petri dishes had been put under the wrong light. |
THis means that our results are in a way invalid because they did not receive one type of light but two. This happened for possibly more than 2 days. Thus, they did not have one independent variable. |

What would you do differently if you were to investigate your SAME question again?
If I did this Same question again I would change the experiment in many ways. For starters, I would only put the seeds under the light for 8 hours. Additionally, I would put the box in a dark room and cut holes in the box to allow ventilation and control the temperature. Finally, I would do more research to find out the appropriate amount of water to give each of our plants. I would then make sure each petri dish was receiving a consistent amount of water.
WaterKingz: I have really enjoyed working with you!
Great job on the Conclusion! You've explained your results really well. Just one suggestion - at the end, you have a sentence that says you didn't get any results. However, you did get results - your results were that the seeds did not germinate. Your statement could say that you were not able to observe the effect of light intensity, but your results did show that high temperatures have a negative effect on seed germination.
Really good work on your project!
Thank you for being our scientist and giving us helpful suggestions throughout our experiment!
Thank you so much for helping us with our investigation really appreciate it.
Thank you so much for being our scientist and communicating with us! We really appreciate it!
