Regrowing vegetables: A fun science activity for toddlers

Regrowing kitchen scraps into fresh vegetables offers an engaging science project for preschoolers and toddlers, transforming kitchen waste into an interactive discovery moment.

At N Family School, converting everyday routines, such as preparing meals, into meaningful learning opportunities is at the heart of what we do, and this hands-on project is a favorite to share with parents. It starts with things you were about to throw away.

What you need

• A clear glass or jar
• Water
• Vegetable ends (try scallions, fennel, leeks, celery, onions, cabbage, or romaine lettuce)
• A sunny windowsill
• A little patience!

Best ages for this activity

This vegetable scrap science project works well for children ages 2 to 5, once they're able to talk about what they notice and help with small steps like checking the water. Younger toddlers can still take part by watching and pointing out changes with you.

Why this activity builds early learning skills

This easy science experiment does more than pass the time. It helps children understand how living things change, what plants need to grow, and why patience pays off. It also opens the door to easy conversations about where food comes from, right at your kitchen counter, and it's a project your preschooler can help lead from start to finish.

How to try it at home

The next time you're prepping vegetables for dinner, pause before you toss the ends in the trash. Take a moment with your child to look closely at the roots and talk about what you both notice. Explain that even though you've already eaten most of the vegetable, it can grow again with a little water.

Place the vegetable end in a clear glass or jar, with the roots submerged and the top poking out above the waterline. Set it somewhere sunny, then wait. Check in each day and top off the water as needed. Most vegetable ends begin showing new roots within about a week, with fresh green growth soon after.

Hands-on discovery like this is exactly what our Lab and outdoor garden are built for. At N Family School, children get to grow real vegetables, watch roots and shoots develop over time, and ask their own questions about what plants need to thrive, the same kind of curiosity this at-home activity sparks right in the kitchen.
