| Research Question | how does the temperature of the water affect how the seed germinates/grows? |
| Predictions | Two of us think hot water will make the plant grow.... And two of us think cold water will make the plant grow |
| Experimental Design | Materials: 40 buckwheat seeds, 4 petri dishes , water. light, Procedure: gather your 40 buckwheat seeds and your petri dishes as well as water and different temps of water ( 60, 70, 80 ) degrees 2. set up your seeds: put paper towel on the bottom of dish put 10 seeds in 2 rows of five petri dishes heat and cool the 5 milliliters of water pour the cool/warm water in two petri dishes after done watering put the lid on the petri dish and wait 3 days to water again once you go to water again measure the growth of the seeds before watering again repeat bullet 3-6 every 3 days |
| Conclusion | How did the temperature of the water affect the germination of the seeds? The hot water had the most seeds that germinated over the week. CLAIM: Warm water produced the plants with the longest roots. EVIDENCE: They average of seeds grown for cold water was 5.22 cm of root length, but for the warm is 6.64, but for warm water we used day 4 data instead of day 5 data because some of the seeds broke and it would not be accurate. The hot water was an average of 6.28. The number represented the averages of the root length of the seeds over the 7 days we measured. The longest root for hot was about 10 cm, cold was about 12.3, and warm was about 19. The difference between cold and hot was 7.7 cm REASONING: The temperature affects the seeds germination, for example, the colder the temperature is, photosynthesis and plant will grow will start to slow down. We looked up the optimal temperatures for buckwheat to grow in and we found out it was 70 degrees fahrenheit, well our warm water had the longest growth. The warm water temperature was around the optimal temperature for buckwheat to grow in. That is why the warm water was more successful in this investigation. Another thing is that buckwheat can survive in the hot water but it would not be as full grown as it would in their ideal temperature. |
