Check at intervals depending on availability, you will see slight results after 3 hours, significant results overnight and again at 48 hours. Cut the bottom of the celery and you can see where the water was transported up into the celery stem.
Fresh Celery stalks with leaves. Preferably the lighter leafier stalks near the center.
Water
Food Coloring
Steps
Explain experiment. We are going to find out how plants absorb water and grow. See Educational note for more.
Separate and select stalks of celery with leaves. Cut about a quarter inch off the bottom. The lighter stalks near the center will show the most color.
Put about 8 ounces of water into glass jar or vase.
Drop 3-4 drops of food coloring into jar.
Place stalks into the water and using stalk stir very gently until food coloring is dispersed evenly.
Have child/class make predictions about what will happen. Write it in a simple sentence and "point and read" together.
Make 2-3 observations and write them down. Check at intervals depending on availability, you will see slight results after 3 hours, significant results overnight and again at 48 hours.
Cut the bottom of the celery and you can see where the water was transported up into the celery stem.
Results
Day 2
This is the result after 24 hours. We added a few extra stalks so that we would have a selection to work with. The celery in the purple took in some color but interestingly enough the leaves withered and did not do well. I tried it again and the same thing happened so there may be something in the purple dye that the celery does not thrive from.
