| Explore | Some things we know about plants are they need light and water to grow or else hey wont grow/die. We also know not every plant will always grow. Also we know we have to keep track of the amount of growth because sometimes it’ll be hard to tell the growth little by little. Plants need very strict monitoring to make sure the lights don’t combine. Another thing we know is that the seeds can’t be too close together. Lastly we have to have control over the plant for example, it can’t be way too cold in here or way to hot. |

| Research Question | How does the different colors of light affect the plant growth? |
| Predictions | We think the different lights don’t change the growth every light does the same. We think this because every color light has every color made up by it. |
| Experimental Design | 1) get a damp paper towel and put it at the bottom of 4 Petri dishes. 2) place 7 pea seeds on each of the Petri dishes on top of the damp paper towel 3) set up each different color of light over top of each Petri dish 4) put bins over top each Petri dish guarding each one from another. 5) track the growth of each pea seed under thr different colors oof light. |
| Conclusion | Claim: If you put seeds under a red light, more seeds will germinate faster. Evidence: If you put seeds under a red light, more seeds will germinate faster. We know this because when we put seeds under four different colors of light(Red, Green, Black, and White) and by day six, the red light seeds grew a lot more, six seeds germinated. The seeds under white light had not grown much and the other colors did but not as much. 5 green seeds germinated, 4 black seeds germinated, and 2 white seeds germinated. Reasoning: If you put seeds under a red light, more seeds will germinate faster. Seeds require light energy to photosynthesize and create glucose to feed off of in order to grow and produce carbon dioxide. The more energy a light contains, the more light it can transfer to a seed. The more energy a seed gets from a light source, the more it is able to germinate. This means that the red light contained the most energy for the seeds and they germinated the most.This investigation challenged my prior knowledge and I was not expecting these results. This experiment was fair because we gave them all the same things except the color of light. |
