| Explore | From our experiences outside of school I know that plants are very sensitive to the amount of light they get to how much water they receive. Another fact that we know about plants is that plants need seeds need to germinate in order to become plants. A question we have about plants is: what types of plants grow in different areas? Is it because of the different temperatures? We know they grow in most places but maybe not deserts. (except cacti and succulents) We want to know? In class we discovered parts of a seed through a bean seed. That really deepened my understanding of the subject. |

| Research Question | Questions: What types of plants need a really cold temperature to germinate? How many plants need a really cold temperature to germinate? Do most plants need a cold temperature to germinate? (all of those questions but for warm) Question to focus on: How does temperature affect the seed growth and germination of different types of plants? |
| Predictions | A prediction we have that extreme outliers could have different reactions too cold or warmth. We believe this is so because the plants have evolved over the thousands of years they have been a species to adapt to specific weather. Another prediction that we have is that the plants that we are growing will germinate around 70°F. We believe this because it is considered in our group the middle and perfect weather and in class we believe Jeff stated this. |
| Experimental Design | In our experiment we decided to work on temperature and we put seeds in then fridge and the incubator and our control was room temperature |
| Conclusion | In trial one of this project, we learned that pearl millet seeds germinate at temperatures around 80˚ fahrenheit. We know this because our seeds that were at higher temperatures (in the incubator) grew very large and healthfully. We also learned that 40˚ fahrenheit is a very, very low temperature for pearl millet seed germination. We can confirm this because our seeds at lower temperatures did not germinate nor grow in any way. When the factor of 40˚ fahrenheit is applied to pearl millet seeds, the seed coat will become a dark brown and they will not germinate. |
