| Explore | We know that plants make their own food through a process called photosynthesis. They also need water and sunlight to grow! In class and background research we have learned that plants have a cell wall and chloroplasts. What effect do different fertilizers have on plants? |
|---|---|
| Research Question | We want to test and study how hydroponic plant fertilizers affect plant growth. We knew we wanted to test effects of fertilizers and measure plant growth. We were not sure what they best approach for this was so we did some research. Well we know what plants need to grow, and that fertilizers have an effect on that so we wanted to test it. |
| Predictions | The possible outcomes were that Nitrogen was not going to help the plants grow anymore than the others because they can create their own Nitrogen and the don't need additional Nitrogen. |
| Experimental Design | Our plan is to grow our pea seeds hydroponically in a greenhouse. We will plant the seeds directly in the rocks (not going to germinate first). The rocks are in a cell hanging above the water. Next we will get our hydroponic fertilizers and add them to our water in the base of our container. Then we will water them with a spray bottle and watch them grow. We will measure their height, observe the amount of leaves they have, and at the end measure their root length. We will record our measurements in our scientific notebook. |
| Conclusion | We came to a conclusion that the plants that were in Calcium fertilizers had the most significant growth. Our data showed that our plants had overall better growth then the rest of the plants. The Calcium helped the plants grow the best because it help hold the plants' cell walls together and helps activate important enzymes. Fertilizers containing Calcium could be used on different seed types or different amounts of Calcium could be used on Pisum sativum plants. |
