| Explore | that the root of the plant comes out the top of the seed and the actual plant comes out the bottom of the seed. and different seeds grown at different speeds. different seeds need different amounts of water. |
|---|---|
| Research Question | How does the amount of water affect the germination rate of a plant? |
| Predictions | If we give the plant more water, then the plant will germinate at a faster rate. |
| Experimental Design | 1. Put the paper towel in Petri dishes (3) 2. Put 10 alfalfa seeds in each dish. 3. Give the first dish 10 drops 4. Give the second dish 20 drops 5. Give the third dish 30 drops 6. See how many of the plants germinated 7. Record the information on a piece of paper 8. Repeat for 6 days |
| Conclusion | If we give seeds more water, then the seeds will germinate at a faster rate. When we gave the 10 drops of water to 10 seeds, only 2 of them germinated. When we gave 20 drops of water to 10 seeds, only 3 of them germinated. When we gave 30 drops of water to 10 seeds, 9 of them germinated. This is because plants need water to go through photosynthesis. The water gives nutrients to the plant that helps them germinate and grow. This supports my prior knowledge because all living things need water and when you give a plant more water, photosynthesis happens at a faster rate. I think the experiment was a fair test because we gave the plants the right amount of water and we gave them the same amount of sunlight. |
