Daily Idea #179: Rainbow Celery

I don’t usually use food in our experiments but this is my one exception. In honor of this week’s Torah Parsha, Noah (Old Testament Bible chapter), we are making a rainbow with food coloring and celery.

Items Needed:

5 stalks of celery (with the leaves still attached at the top)

5 jars or glasses

water

food coloring

Start by filling each jar halfway with water. Then mix in some drops of food coloring with each jar (if you have the food coloring pack with only primary colors you can have your child make orange, green, and purple by mixing the correct primary colors— red and yellow for orange, blue and yellow for green, and blue and red for purple). Place each celery stalk in the different jars and let them sit overnight.

Tomorrow morning, have your child observe what they see. If they are old enough, they can write a few sentences about what happened. If they cannot write yet, have them draw a picture with their observations.
