It’s pretty clear that science is everywhere including in the kitchen. Most of our classic science experiments use basic kitchen ingredients. That makes for a lot of learning with only a few simple materials. We decided to try to regrow lettuce from the ends of our romaine hearts to see what would happen. Check out how to regrow lettuce from our simple steps below.

For our regrowing lettuce activity, we simply used the stumps of two romaine hearts. You could also do this activity with any other lettuce you have on hand.

STEP 1:  Place the lettuce hearts in a shallow container of water. Make sure the water does not cover the lettuce.

STEP 2. Change the water each day.

Within a day, we had results. Within a week we had new lettuce leaves and a sandwich worth of 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 romaine 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.

  1. We conducted an experiment using 3 different types of water. Coconut, purified and tap…purified was best! Conducted experiment twice…changed water daily, measured growth daily
