| Explore | My name is Karly. I like crafts and doing gymnastics. I have had a decent amount of experience with plants. Me and my mom plant fruits and vegetables in our backyard garden. We also have many plants inside that I repotted and watered. For example Calla lilies, cucumbers, money trees, tomatoes, and more. I am excited to explore and learn more about plants. Hi, my name is Rachel, and I am a seventh grader at DeWitt Middle School. I love to be outdoors. I have a lot of experience with growing plants. Every year, my family and I grow a garden. We grow cucumbers, carrots, peppers, corn, tomatoes, peas, zucchini, sunflowers, and more in the garden! I always have a lot of fun growing things, so I can't wait to do it with you. Hello, my name is Harper I love cooking and crafting. I have a little experience with plants: one of my favorite decorations are plants. we used to have succulents but we sadly killed them all because we were watering them with the wrong type of water. We also have a garden last year we only ended up with cucumbers, zucchini, and a couple of herbs. Unfortunately, the chipmunks got to the watermelon and peppers before us. I was a little involved in watering the plants and harvesting them. |

| Research Question | How does the amount of sugar in water affect a plant's germination rate? |
| Predictions | We predict that the seed will germinate faster with 5 milliliters of sugar in the water. We think the water with 5 milliliters will germinate the seed the fastest because 15 milliliters of sugar will be too much. |
| Experimental Design | 1. Gather materials 2. Place a paper towel piece in each petri dish 3. Place 10 seeds on each paper towel piece about 2 centimeters apart 4. Get a beaker and add 100mL of tap water 5. Repeat step 4 twice Set one cup to the side Add 5 mls of sugar to the tap water Add 15 mls of sugar to a different beaker of water Mix the cup with 5 mls of sugar and set it to the side Mix the cup with 15 mls of sugar and set it to the side Put 3 drops of tap water onto each seed in one of the petri dishes Put 3 drops of the water with 5 mls of sugar onto each seed in another petri dish Put 3 drops of the water with 15 mls of sugar onto each seed in the last petri dish Now wait and watch the germination rate |
| Conclusion | The claim we found from our investigation is that sugar is good for a plant up to a certain point. Sugar in water is good for a plant up to a certain point, this is true because the seeds that were watered with 5 grams of sugar grew the least. The seeds that were watered with 2.5 grams of sugar grew the most this proves that some sugar is good but to much can stunt the growth of the plant and even kill it. The seeds watered with tap water were right in the middle they had a good amount of growth but not as much as the 2.5 grams of sugar seeds. This showed that too much sugar can clog the pores and not let enough water in to germinate the fastest. In the future we would have more treatments to see what the point is where the pants would not germinate. |

| About this Project | This group wowed me with their communication with their mentor. They consistently uploaded photos of progress and wrote out descriptions for their data. Additionally, their final conclusion statement was well thought out and included how their mentor influenced their experiment. -- Devani Jolman, Scientist Liaison |
