Outside of school, all of our group noticed how different plants could survive in different climates. We saw how Palm Trees thrived in hot environments and Pine Trees survived in cold ones. We thought it was interesting how plants had these different adaptations, so we wanted to see how our seeds, (pea seeds) could survive and germinate in different environments |
Research Question |
The question that we are answering is, "How does temperature affect seed germination." We came up with this by thinking about what seed we chose (pea seed) and what temperature it normally grows in. We thought it would be a cool experiment to see how our seed grows in other temperatures. This question fits in with what we know about the topic because we know that all seeds prefer certain temperatures and it is interesting to see how seeds grow in temperature that they don't normally grow in. |
Predictions |
We decided to study how temperature would affect the seeds germination. We decided to work with the pea seed. The possible outcomes could be that the seed germanates more in one temperature or fail in other temperatures. We thought that the pea seed would germinate more in the hot temperature since we thought the seeds would freeze in the cold and that the room temperature would be a bit too cold for the seed. |
Experimental Design |
Our experimental design is to put three different groups of pea seeds in three cupboards with the same environment, except for the temperature. They all have the same amount light, water, oxygen etc. One of the groups is placed on a heating pad, the other is in a room temperature cupboard, and the other is in a refrigerator. We then record how fast the seeds germinate and if they germinate at all, and by the end, we will know which temperature works best for pea seeds. |
Conclusion |
We know that part of our hypothesis was supported.
We know this because we said that the seeds on the heating mat would germinate faster/better but the room temperature ones germinated faster/better. We also said that the refrigerated ones would germinate slowly which they did.
This means that our hypothesis was correct on the cold temperature, but we didn’t get it right on the fact that room temperature is the best temperature to grow pea seeds. Not hot temperature. Therefore only half of our hypothesis was supported. |
