Plants grow using photosynthesis. They need water, sunlight, oxygen, and sugar. Germination is when a seed starts to grow. Germination mostly stops when the plant comes above the ground and photosynthesis can start. Cellular can also take place in plant. The inputs of cellular respiration are oxygen and glucose and the outputs are ATP energy, carbon dioxide, and water. |
Research Question |
How does the amount of water affect the rate of germination? |
Predictions |
If we add more water, then the seeds will germinate faster. |
Experimental Design |
Procedure: Step one - Place paper towel on the bottom of the petri dish
Step two - Put 10 radish seeds in each petri dish (there will be 3 petri dishes)
Step three - Wet each paper towel with the correct amount of water
petri dish 1 will have 1mL of water
petri dish 2 will have 3mL of water
petri dish 3 will have 5mL of water
Step four - After one day (the beginning of each class) put a different amount of water on each paper towel
Step five - Repeat the watering process until all seeds are fully germinated
Step six - Record all observations about how quick each set of seeds germinate |
Conclusion |
Th amount of water does effect the rate of germination. If you do not add enough water, the seeds will take a long time to germinate or will not germinate at all, but with that being said, if you add too much water the seeds might rot or mold |
