How does a pumpkin grow?

Last week we looked at a white pumpkin and an orange pumpkin.

We wondered if the insides of the pumpkins were the same or different. Did they look, smell or feel the same? We recorded our predictions. Next, we cut open the pumpkins.


 



That afternoon, we talked about what pumpkins need to grow. We knew they needed: 
  • seeds
  • water
  • sun
  • soil

We wondered what would happen if we put soil and water in our pumpkin. Would the seeds grow?



Over the next week we watched and watered the soil and seeds. We created a pumpkin observation chart and recorded daily. 



On Monday we noticed two small sprouts! We talked about why they were growing near the side of the pumpkin (because the seeds are on the side of the pumpkin, not in the middle). 


On Wednesday we observed that there were three sprouts and they had all grown. But, we also noticed that the pumpkin was getting rotten and moldy. We decided that it was time to throw out the pumpkin. 

But we still wanted to observe the sprouts and watch them grow. We decided to replant the sprouts. 


 





When we transplanted the sprouts, we made a very interesting discovery. Some of the seeds deeper in the pumpkin had begun to sprout too! We just couldn't see them under the soil. They were developing roots.
