Time Flies When You’re Having Fun: A DIY Sundial for Kids

1000 Views

Remember those lazy summer days of childhood, where time seemed to stretch on forever? Tap into that sense of wonder and discovery with a fun and educational DIY project that's perfect for budding scientists: a sundial!

This isn't just about crafting; it's about connecting with the natural world and understanding the concept of time in a tangible way. Plus, it's a fantastic opportunity to sneak in some STEM learning without the pressure of a classroom setting.

What You'll Need to Become a Timekeeper

  • A Paper Plate: This will be the face of your sundial.
  • A Wooden Dowel (or a Sturdy Straw): This acts as the "gnomon," casting the all-important shadow.
  • Playdough or Clay: To secure the dowel to the plate.
  • Number Stickers: To mark the hours.
  • Tape: For extra reinforcement.
  • A Sunny Day: Because, well, it's a sundial!
  • A Clock or Timer: To keep track of the real time.
  • A Pencil or Something Sharp: To make a hole in the plate.

Let's Get This Sundial Show on the Road!

  1. Prep Your Plate: Carefully poke a hole in the center of the paper plate. Make sure it's large enough for your dowel or straw to fit snugly.

  2. Secure the Gnomon: Push the dowel through the hole in the plate. On the underside, use the playdough or clay to secure the dowel in place. This will keep it upright and stable.

  3. Find Your Sunny Spot: Choose a location outside that receives sunlight throughout the day. Place your sundial on a flat surface. If it's a windy day, use a few rocks or heavy objects to keep it from blowing away.

  4. Mark Your Starting Point: Check your clock – let's say it's 8:00 AM. Carefully observe the shadow cast by the dowel. Place a piece of tape along the shadow line and stick the number sticker "8" at the end of the line.

  5. Hourly Check-Ins: Set your timer for one hour. When it goes off, head back to your sundial. The shadow will have moved! Place a new piece of tape along the shadow line and mark it with the corresponding hour (in this case, "9").

  6. Keep on Tracking: Repeat the process of marking the shadow every hour until the sun sets, or the shadow becomes too faint to see clearly.

The Science Behind the Sunshine

As you and your child work on this project, take the opportunity to explain the simple yet fascinating science at play. The Earth rotates on its axis, and as it does, the sun appears to move across the sky. This movement causes the shadow cast by the dowel to change position, allowing us to track the passing of time.

Making it Your Own

  • Get Creative with Decoration: Let your child personalize their sundial with colorful markers, paint, or other craft supplies.
  • Explore Different Locations: Experiment with placing the sundial in different spots throughout the day. Does the shadow change more quickly in some locations?
  • Research Other Types of Sundials: Did you know there are many different types of sundials? Encourage your child to learn about some of the more elaborate designs.

Time Well Spent

This DIY sundial is more than just a craft project – it's a hands-on learning experience that combines science, art, and a healthy dose of outdoor fun. So gather your materials, embrace the sunshine, and get ready to watch time fly by!

Did You Know? The position of the sun in the sky changes depending on where you are on Earth. That means your sundial will be unique to your location!
