Growing lettuce from the ends of romaine hearts!

Fascinating, Simple kitchen science idea for kids.

It’s pretty clear that science is everywhere including the kitchen. Most of our classic science experiments use basic kitchen ingredients. That makes for a lot of learning right tin the home. We decided to try growing lettuce from the ends of our romaine hearts to see what would happen. Check out growing lettuce from our simple steps below and make sure to visit our 25 Classic Science Experiments Page to find more ideas.

Growing lettuce is so simple to do and so cool to watch.

For our growing lettuce activity, we simply took the stumps of romaine hearts and placed them in a shallow container of water. We changed the water each day. Within a day, we had results. Within a week we had new lettuce leaves and a sandwich worth a lettuce. Make sure to move your lettuce into the sun as well.

Make sure to look at the roots growing from the bottom of the lettuce end too!

Growing lettuce has a bit of science.  The roots grown in water are different from the roots grown in soil. The water does not supply nutrients so the type of growth is different. We could not produce a full head of lettuce. Buds from inside the stump are what begin to grow. However, growing lettuce with kids is simple kitchen science fun.

We had some great leaves form, but just a little bit taller than this is where they stopped growing.
