| Explore | A way that a seed is dispersed could be through a fruit or an animal or through a leaf, this means there are many ways to spread seeds around! A seed has to figure out if the conditions are right and when they decide it is right they start to germinate. germination is the process for when seeds start to grow. When a plant starts growing it has to break out of the seed first. Yesterday we had a disscousion about how when a cucumber seed is in a package it is still alive. |

| Research Question | How does light intensity affect seed germination? |
| Predictions | If the seed is under the medium intensity light then the seed will germinate first. I believe this because if the seed has no light I think the seed will not know to start germinating. And if the seed has to much light then it will dry out. |
| Experimental Design | 1- gather materials: seeds, petri dish, wet paper towel, lamps 2- Assemble petri dishes with 15 Nasturtium seeds in the 3 petri dishes 3- Assemble light source 4-Place the petri dish under the 60 watts, 100 watts and one with no light 5- Record data when the seed/ seeds start to germinate |
| Conclusion | A seed with 0 light will germinate first compared to the 60 watt light and the 100 watt light. On day four we had one seed sprout from the 0 watt light out of all the seeds. All the other ten seeds that were in the 60 watt light and 100 watt light just got moldy in the petri dishes. This evidence did not support my previous knowledge. This happened because the seed thought that it was underground and ready to germinate. This also occured because the seeds with mold on them could've been prevented by growing because of it. |
