| Explore | We are exploring how the temperature affects the growth of corn. We know that corn usually grows in warm climates so, we were interested in testing the growth of corn in colder temperatures. |
|---|---|
| Research Question | How much does the temperature affect the corn seeds' germination and growth? |
| Predictions | We think that in the colder climate (the fridge) the corn seeds won't grow as much. The corn seeds don't usually grow in cold temperature; in the fridge, it is 12 degrees Celsius. We think the cabinet will have a better chance of growing more because the temperature is alike to the standard climate in corn fields. |
| Experimental Design | We have put 3 corn seeds, spread apart, closed in a CD case. There is paper towel accordion folded inside the CD case with the corn seeds in between the folds. We had a little bit of the paper towel hanging out of the CD case. Did this twice and we put one group in a cabinet and the other in a fridge. We had to put one group in a cabinet, because in the fridge there is complete darkness; we need to control the amount of light the both groups get. When we collect our data, we measure the whole seed, top to bottom, in centimeters. Example: FAR RIGHT SEED: ___ cm MIDDLE SEED: ___ cm FAR LEFT SEED:___ cm. Our picture of our set up, our data collecting documents, and our slide is in 'files'. |
| Conclusion | After collecting data for a few days we saw a big difference in growth. The most growth in the cabinet group was 33 cm long where in the fridge group, the most growth was 1.5 cm. Here we clearly see that corn seeds grow better when the conditions are warmer. We also found out that corn seeds' cells will freeze and water will stop flowing through the plant; this is a part of why the seeds in the fridge didn't grow as much as the group in the cabinet. |
