Easy DIY Activity Planting With Kids: How To Start Seeds in Cartons (Living vs. Nonliving Lesson)

April 13, 2025

This blog may contain affiliate links. If you choose to take action (and I hope you do!), I will earn a commission. I have chosen these products because they are awesome and helpful, not because of the small commission I will receive. Thank you!

When I teach about living versus nonliving I love to incorporate this easy DIY activity of planting with kids. Planting with kids is such a great hands-on activity for students and it can be done in the spring or the winter.

This activity and lesson is great for students of all ages, but I would reccomend Pre K – 5th grade. We’ll be using recycled containers like milk cartons and egg carts to help support plant growth and show how nonliving objects can play a role in helping living things thrive.

Science is all about curiosity!

We’ll use this DIY activity planting with kids to encourge students to explore the world around them by observing nature, ask questions, and use these everyday objects in creative ways.



You’ll want to first introduce the concept of living and nonliving things.

How to determine if something is a living thing? Here are some questions your students can ask:

  • Can it grow?
  • Can it move?
  • Can it breathe?
  • Does it need water to surive?
  • Can it reproduce?
  • Does it need food to survive?
  • Can it die?
  • Does it respond to it’s environment?

This video is great resource for teaching younger students (Pre K – K) about the concept of living and nonliving things:


I love this video for elementary students! It challenges the question what makes something alive?


Based on the criteria above, we know that plants are living things!

Plants grow and move (even if it’s very slow), plants reproduce, need water and food, and respond to their environment.

This planting with kids activity can help students understand the difference between living and non living things because they will be able to identify the different elements of the activity and determine whether it is living or non living.

Reusing cartons and containers for this planting with kids activity also makes it a great idea to do during spring or for Earth Day!

With this acitivity students will be able to:

  • learn about the importance of plants
  • identify living and non living componets
  • explain the difference between living and non living things
  • understand that plants need nutrients, air, water, light, and a place to grow

  • Explain how milk cartons, egg cartons, and boxes can act as small planters for growing seeds.
  • Discuss the benefits of using recycled containers—cost-effective, eco-friendly, and easy for kids to decorate.
  • Mention any potential challenges (e.g., making sure there are drainage holes so the seeds don’t get too wet).
