Project Information
Many students think of the scientific method as a step-by-step process that all scientists follow in order. But real research is rarely so neat and tidy…it is really more of a research cycle or spiral because things you learn in one step can change your ideas about what you’ve already done or about next steps.
It is OK to change your thinking! We encourage you to go back and edit things you write in this section at any time as your ideas change. Just remember to explain your changes in your updates feed.

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 affect the plant in different ways. Those are some things we explored doing this project. |
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 different amounts of worms in each 2-liter bottle. This is how the question fits what we know about the topic. |
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 the dirt and plants will be. The variables are amounts of worms. We will put one worm, then five, then ten. We will measure how tall the plants grow in millimeters. The constant variables are the amount of water, amount of sunlight, type of soil, amount of soil, and container size and shape. We will record our data (plant height) in google sheets. That is the experimental design. |
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 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. |

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 compare them with their original hypothesis. - Nancy Ramig, Teacher |
