| Explore | Outside of school we know that plants need sunlight, water, and oxygen to make food. In class and in background research, we discovered that ryegrass plants have leaves that are green, tough, as well as dark and that ryegrass plants have extensive root systems that are useful for erosion control. The questions about plants that interest us are “Will different types of liquids still make ryegrass seeds grow?”. |
|---|---|
| Research Question | We want to test different types of water’s effect on the growth of ryegrass seeds. Our group had discussions to come up with the question. The question fits what we know about the topic because we know that plants need water to grow. |
| Predictions | If we plant 10 ryegrass seeds in containers with different types of water, then the seeds planted in regular water will grow the tallest. We think this will happen because plants only use regular water to make food and to germinate. |
| Experimental Design | We will cut three 2-liter bottles in half. We will then plant 10 ryegrass seeds in each container. We will use carbonated water, flavored water, and water to water our plants. We will watch our plants every day, and take notes on them. This is our experimental design. |
| Conclusion | The hypothesis was if 10 rye grass seeds are planted in containers with different types of water, then the seeds with just regular water will grow the tallest which was supported by our evidence. Evidence showed that bottle A, the bottle with regular water grew the tallest with an average height of 620mm. In a future experiment we would use different types of soil as an independent variable. Another idea for a future experiment on rye grass might be to put each bottle in a different location to get a different amount of growth. |

| About this Project | Team spirit - optimism even when seeds didn't start to germinate as quickly as others. Their online communication was great with their mentor and the journals they wrote their observations and findings in were done with great organization. - Nancy Ramig, Teacher |
