Plant Experiments

Many of the activities on these pages may require adult supervision.
Be sure to tell a grown-up about what you're planning and ask for permission before getting started.

Easy to do in the kitchen.


1. Colored Celery

Cut across the stem of a stalk of celery and stick it in a glass of food coloring. Leave it 24 hours. The next day take it out and slice the stalk across. You will see how the veins in the stalk carried the color up into the plant.

2. Life of Lima

Curl a thin sponge around the inside of a glass jar. Put two or three dried lima beans between the sponge and the glass. Pour in enough water to dampen the sponge. Don't cover. Set in indirect sunlight, somewhere where you will notice it each day, and be patient. Check daily to make sure the sponge is damp. Soon the limas will sprout. Each will send roots down and a shoot up. How do the limas know which way is up? Good question.
Ask your science teacher.

3. A Live Birthday Card

Wet a sponge and set it in a shallow bowl. Sprinkle cress seeds in the shape of the number of the birthday of the person who will receive the card. Set the seeds where there is indirect sunlight. Check each day to make sure the sponge is damp but not too soggy. If you add water, don't dump it directly on the seeds. As the seeds sprout, they will lean toward the light. Turn the dish around every so often to keep them growing straight up. You can get cress seeds by the package where seeds are sold: hardware stores, garden centers, or nurseries. Read the instructions on the package to find out how long you need to wait until the seeds sprout, and plan ahead so the number is green and growing in time for the birthday. If any seeds grow in the wrong place, weed them out.
