The Tunnel Boring Challenge, a Great Civil Engineering Activity for Kids

Civil engineering is more than bridges and towers. Civil engineers create infrastructure that makes our lives possible. Every day, civil engineers are at work designing subway systems, safeguarding the water supply, and ensuring highway safety in and through mountains.

But how can adults give kids accessible, understandable, and fun ways to explore infrastructure? A cover graphic for the Tunnel Boring Challenge features a small tunnel over a two-lane road in the woods

It’s time to think inside of the fridge.

We are constantly boring through apples whenever we try to remove their core. What if we encouraged kids to experiment with strategies they could use to bore through different fruits and vegetables?

This activity is a perfect home-based engineering challenge. To start your thinking, what would happen if you tried to drill a tunnel through a:

  • Cantaloupe?
  • Zucchini?
  • Tomato?
  • Banana?
  • Orange?
  • Watermelon?

Organize a construction crew equipped with kitchen tools, and see what kind of tunnels you can create! I’d love to hear about your tunneling adventures in the comments.
