Materials: romaine lettuce heart, knife, clear jar or bowl, toothpicks, water, magnifying glass, paper, crayons
- This super simple experiment lets children watch a plant sprout in real time.
- Cut the bottom off a heart of romaine lettuce. Put four toothpicks in the bottom of the heart to hold it up, and put the heart in a bowl. Add enough water so the bottom of the heart sits in an inch of water and the top is sticking up. Put the bowl in a sunny spot, and check it daily. If the bottom of the heart is not submerged, add water. It should sprout within days and grow quickly.
- Set up an observation station with paper, crayons, and a magnifying glass. Have children stop by a few times a week to examine the lettuce. What is happening? How is it changing? Have them draw what they see. observation and recording
