| Explore | Yesterday I did research on our seeds and I found that peas should be kept moist to be able to germinate, and that peas should be planted 1 inch deep. |

| Research Question | How well do plants grow in extreme temperatures? |
| Predictions | If the peas thrive better in cooler temperature, then they might thrive better in the cold rather than the hotter temperatures, because the peas are a winter plant and are sensitive to heat, and don't thrive well at under Fahrenheit 40 Fahrenheit. |
| Experimental Design | Question: How well do plants grow in extreme temperatures? Why this Question: We chose this question because we wanted to know how temperature when growing a plant. We also wanted to know what effects the temperature would have on the plants. This question is also a topic of interest and no one else was doing it. Research: -Extreme heat will make the plant lose moisture and slow down the growth -Good temps depend on seed/plant -Peas usually grow in the cold, and young plants can tolerate light frost. Peas can sprout well between 600 and 500 degrees Fahrenheit, but weather no colder than 400 Fahrenheit. Peas do not do well in heat. -Once planted, peas need little attention other than watering and harvesting. Pests and diseases are rarely a problem, particularly if disease-resistant varieties are planted. Just keep an eye out for aphids on the pea plants and get rid of them with a sharp spray of water from the garden hose. - Burpee how to grow peas. The temperature of space/air. Dependant variables: 1.light amount 2.water 3.water temperature 4.light type(color) The controlled variables are water, soil, size, seed, space. Hypothesis: If the peas thrive better in cooler temperature, Then they might thrive better in the cold rather than the hotter temperatures Because the peas are a winter plant and are sensitive to heat, and don't thrive well at under Fahrenheit 400 Fahrenheit. When they grow in the heat, I predict that they will grow slower. As I said before, these peas are sensitive to heat and will run low on moisture. |
| Conclusion | Our conclusion is that our hypothesis was not supported because the hot seeds did not sprout, but the control seeds did, meanwhile the cold ones, did not sprout. |
