Science: Strong stems and zylem

Bekah’s most recent science unit has been on plants and we’ve been experimenting with celery. A few days ago we left a celery stalk out on the counter so it would wilt overnight. The next morning, we added some food coloring to a glass of water and stuck the celery in it so it would perk back up. Within a few hours, the blue water could be seen in both the stem and the leaves. We left it there a couple days and then today cut it up and created Ants on a Log at Bekah’s request. 

Zylem: tiny tubes that act as elevators to carry water up the stem and to the leaves

Look closely at the cross-sections of the celery and you can see some blue…
