Info

Explore Explore: We know that a plant needs sunlight, water, and soil to grow. We learned that Pearl Millets grow slowly and have good protein. We also learned that the amount of worms can change how fast It can grow. The average height was about 80 millimeters. How the plant interested us is how worms...
Research Question We wanted to study how earthworms affect the growth of a plant. The hypothesis was if ten pearl millet seeds were planted in a 2-liter bottle with worms, then the one with the most worms would grow the healthiest and tallest. We wanted to know how worms affect the growth of a plant so we put...
Predictions Predictions: If 10 pearl millet seeds were in a 2 liter bottle with different amounts of worms, then the one with the most amount of worms will grow the healthiest and the tallest in mm. Those were our predictions with our seed pearl millet.
Experimental Design Experimental design: Our plan for this project is to measure the different heights in a pearl millet plant with different variables such as worms. We have two 2 liter bottles and we will fill them with dirt and water under them, by cutting off the top and flipping it upside down. That is where...
Conclusion Conclusion: This is our conclusion for the Pearl Millet plants. The hypothesis was if ten pearl millet seeds were planted in a 2-liter bottle with worms, then the one with the most worms would grow the healthiest and tallest. Our hypothesis was supported in this experiment. Evidence showed that...
About this Project This team identified the bottle design that was an easy way to set up and compare the growth of seeds as they germinated. They did a great job of communicating with their mentor and sharing the progress of the experiment. At the end of the experiment they were able to analyze the results and...

Dear Priceless Millets,

That is SO COOL that you got some difference in plant height, and you even got evidence that supported your hypothesis! Take joy in that, and if you go into science in the future remember this success and to keep pushing forward even when experiments fail, because some inevitably will! 

Would you be able to copy your data into the text box here? I can't see all numbers and the average is missing for 11/6. I'd love to put it in excel and help you run the numbers with statistics to see if they were significantly different! 
A few questions to think about, how do you define healthy, would you include how green they look or if they are growing upright?

Do you have some ideas of why the greatest number of worms helped the plants?

That's too bad they are starting to die. Could that be because the don't have enough water or they got too much? Too much water can lead to fungal growth--did you notice any? The bad odors you noticed can indicate anaerobic bacteria are growing and those can cause plant disease. Anaerobic means they grow best where there is no oxygen, such as in stagnant water or in soil that is kept very wet!

Great job on data collection and reporting results and conclusions, hope you get to plant more seeds and perhaps grow your own gardens! If you have any questions about science, research, plants, etc. feel free to ask your teacher to email me your questions.

Best wishes and Minnie Pearl will be so happy to hear that, thank you!!

Dear Mr. Bennett

Thank for helping us throughout this project and with our mentor situation. We could not of gotten through this awesome project with out you.  Have a great day with you and Minnie Pearl.

Observations

 

Today we made our final observations and we wanted  to share. One observation was that they started to drop and make weird odors.

Second observation was that all the plants are starting to curl and shrivel. (Sorry for sending it that late I was pretty busy today)

Dear, Mr. Bennett,

This is our conclusion for the Pearl Millet plants. The hypothesis was if ten pearl millet seeds were planted in a 2-liter bottle with worms, then the one with the most worms would grow the healthiest and tallest. Out hypothesis was supported in this experiment. Evidence  showed that the bottle with ten worms was the tallest and healthiest . In a future experiment, we could have more sunlight. Another idea for a future experiment on Pearl Millet, we might add different types of worms.

Have a good day!

I don't know why those uploaded upside down this time, I have no control over how they get posted! 
Have a great week,

John

Hi team! I imagine you're busy in the school semester and finishing up data collection for your experiment! Just thought I'd share some of my plants as well, I posted a photo of the carrot seedlings I have at home for my garden and will next show you the apple trees I am tending at work. Even though it is fall they are blooming in the greenhouse!

Dear Pearl Millets,

Thank you for the update! That's very exciting, I'm glad you have sprouting seeds! Now that you have some plants growing what initial results can you get from your observations? Such as what is the percent of seeds that germinated for each pot? It's kind of rare when I plant seeds to get the same number of seeds that germinate in each group!
Good observation about bottle B, do you have any idea why they are not doing as well, such as do you see any differences in how wet the soil looks? In plant science we want to always be acting as detectives, trying to find evidence whenever we see something odd we can't explain. 
Finally if you can take measurements of each seedling's height on one day we can work together to analyze your data and see if there is a statistical difference! Statistics use math to help us determine if there is a real effect being caused by your treatments, which in this case is earthworms, or if it is likely just random chance! I use it all the time at my work and it's exciting to get my own data and see differences. 

Until next time, 
John

Dear Mr. Bennett,

Two qualitative observations are that each bottle, A, B, and C, have 7 plants sprouting. Another qualitative observation is that bottle B, which has 5 worms, has not been doing as well as bottle A, which has 1 worm and bottle C which has 10 worms. Hope to hear from you soon.
