| Explore | Plants need water,soil, ect to survive There are many difffrent types of plants Plants need the right envirorment, soil, water to germinate Plants can grow into food, flowers ect Plants take in carbon dioxide and relaease oxygen (photosynthsis) We need plants to better our ecosystem. |

| Research Question | Does changing the type of liquids affect how many seeds germinate? |
| Predictions | If I take I have different liquids and pour them into a seed, then it will affect the seeds germination. The other liquids are not made up of the same nutrients that the plants need when they are given water. So it is very possible that the other liquids will stunt the plants germination |
| Experimental Design | 1. Put paper towel on the bottom of pertri dish 2. Put 10 pea seeds on the paper towel, try to make evenly spaced. 3. Give water to seeds 4. Close the petri dish 5. Continue to water every other day for a week. 6. Repeat steps 1-5 but give seeds in another perti dish half water half orange juice mixture 7. Repeat steps 1-5 but give a third pertri dish with 10 seeds orange juice. 8. Observe how many seeds germinate in each dish. 9. Record how many germinate in each dish 1. Put paper towel on the bottom of pertri dish 2. Put 10 pea seeds on the paper towel, try to make evenly spaced. 3. Give water to seeds (4 ml) 4. Close the petri dish 5. Continue to water every other day for a week. 6. Repeat steps 1-5 but give seeds in another perti dish half water half orange juice mixture (2ml each liquid) 7. Repeat steps 1-5 but give a third pertri dish with 10 seeds orange juice. (4 ml) 8. Observe how many seeds germinate in each dish. 9. Record how many germinate in each dish |
| Conclusion | Claim: The type of liquid does affect how many seeds germinate. Evidence: The water petri dish had the most seeds grow. There were 10/10 germinated seeds. The orange juice dish had 8/10 seeds germinate. The orange juice and water dish also had 8/10 seeds germinate. Although the orange juice and mixture had the same amount of germinated seeds, the mixture we considered 2nd healthiest because there were longer roots on the seeds then the orange juice seeds. Also the orange juice had some seeds that were moldy and they did not have very long seeds. Towards the end also the paper towel and orange juice on it also started to get moldy too. So all together we think that the healthiest seeds were the ones who were given water, the second healthiest seeds were given orange juice and water mixture, and the not so healthy seeds were given orange juice. Reasoning: This is because when you give a plant a liquid with a good amount of sugar it can stunt their growth. In this case, orange was the sugary liquid we gave our seeds. Now if you put a small amount of sugar in the liquid you were giving the seeds, the plant would turn out healthier. But the orange juice had too much sugar, therefore the juice stunted the plants growth and made it the least healthiest. The sugars in orange juice make it hard for the plants to absorb water. So, the water in the orange juice that the plant could use to benefit it can be used because the sugars make it that the plant cant absorb the water. Also, the orange juice seeds were starting to have microbial growth on them. This means that harmful things were growing on the seed because of the orange juice. Next, the mixture between the orange juice and water grew the second most. Since the amount of sugar given to the plant was cut in half, a clear difference was seen between the pure orange juice container and the mixture. The mixture’s container had less microbial growth happening and the seeds looked a lot healthier. Now, the water one was the healthiest. There was no sugar in the water. So, the seeds grew the most and had zero microbial growth. Now, according to my secondary knowledge probe if we added a little bit of sugar into our water the seeds maybe would have been even more healthier and grew even faster. In conclusion, the more sugar a liquid has, the less the plant will benefit from it. |
