Pumpkin Jack. In this story, a boy named Tim carves a Jack-o-lantern and names it Jack. He enjoys watching Jack's glowing face in his room each night, until Jack begins to go bad and Tim's mom makes him get rid of him. Tim puts Jack out in the garden and watches him continue to decompose and change throughout the seasons.
You can observe a pumpkin and how it changes as it decomposes too. Every few days make an observation of your pumpkin. You can take a picture like I did, or draw what you see. Make some notes. You can use this printable observation sheet to keep track. If you put it on the refrigerator or a bulletin board where you will see it often you can observe your pumpkin throughout the fall and maybe even in the winter and spring.
- What color does your pumpkin change?
- Does it get moldy? What does it look like?
- Did you get a frost? What happens to your pumpkin after a frost?
