Free “Make a Sundial” Project — Perfect for STEM, Outdoor Science, and Classroom Fun!

Hey everyone! We are approaching the winter solstice, which makes it a great time to explore light, time, and space science concepts!

Why Making a Sundial Is a Fun Project for All Ages

Creating a sundial is one of those magical STEM projects that never fails to impress learners! From curious kindergarteners to middle-school scientists and even adults who love hands-on discovery. There’s something exciting about using simple materials like a paper plate, pencil, or stick and turning them into a working time-telling tool powered entirely by the sun. It feels like a mix of science, art, engineering, and a little bit of ancient history, all rolled into one. Kids love watching the shadow move as the day goes on. Older students enjoy understanding the “why” behind it. This project is a perfect fit for multi-age classrooms, homeschool families, and outdoor learning groups.

What We Can Learn From Building a Sundial

A sundial may look simple, but it teaches some incredibly big science concepts. When students build and test their own sundial, they’re discovering how Earth’s rotation creates day and night, why shadows change direction and length, and how humans used natural patterns long before modern clocks existed. It’s a hands-on way to explore astronomy, Earth science, solar energy, measurement, and observation skills. Students begin noticing where the sun rises and sets, how shadows shift through the seasons, and how ancient civilizations tracked time by watching the sky. These real-world connections make science feel meaningful and alive.

More Than Science—It Builds Curiosity and Confidence

Sundial projects also spark creativity and problem-solving. Kids get to design, test, adjust, and improve their sundials. They experiment with materials, locations, and angles, learning through trial and error. Whether done in a classroom, backyard, nature center, or summer camp, making a sundial encourages students to slow down, observe nature, and engage in authentic inquiry. Best of all, it gives learners of all ages the confidence that they can build something functional with their own hands—something that uses the power of the sun to tell time!

If you’re looking to bring a hands-on science project into your classroom — one that’s inexpensive, educational, and perfect for elementary students — you’ll want to check out Make A Sundial: Project Instructions, Materials List + More on Teachers Pay Teachers.

This free, printable activity guide makes it easy for students to build their own working sundial using simple, everyday materials — and start exploring time, shadows, earth science, and solar movement in a fun and memorable way. 

What Makes This Sundial Activity a Winner

• Ready-to-use & no-prep printable — Just download, print, and you’re ready to go. Perfect for busy teachers, homeschool parents, or summer-camp leaders.
• Simple materials, big learning — Students only need basic supplies (like a paper plate and a straw or pencil) to build a sundial and explore how shadows change with the sun’s movement.
• STEM + Earth Science + History — The resource includes sundial construction instructions, a materials list, historical context (like how ancient civilizations used sundials), and links to broader STEM and earth-science ideas.
• Engaging for all learners — Great for independent work, small groups, or center rotations. Also ideal for cross-curricular tie-ins (science, history, outdoor learning).
• Versatile setting — Works for classroom science units, outdoor lessons, homeschool projects, summer camps, nature centers, or even family learning.

Why Using a Sundial Project is Such a Great Teaching Moment

Sundials are more than just a fun craft — they open the door for deeper learning. When students build their own sundial and observe how shadows move with the sun, they begin to understand:

• How the Earth’s rotation impacts day and night
• How ancient peoples tracked time long before clocks existed
• Historical connections — how technology and timekeeping evolved over centuries
• Basic science and engineering: measurement, observation, design, and problem-solving

This hands-on, minds-on experience can spark curiosity about astronomy, Earth science, solar energy, and human culture — all through the simple act of watching a shadow move.

How You Could Use It in Your Classroom or Homeschool

• Outdoor science lesson: Take students outside on a sunny day and have them build and test their sundials. Then record shadow changes throughout the day.
• STEM challenge: Encourage students to improve their sundial design — maybe experiment with different materials, angles, or locations — to explore what makes the sundial work best.
• History + science cross-curricular activity: Pair the sundial activity with a mini-lesson on how ancient civilizations kept time, and compare with modern clocks.
• Nature or camp setting: Use for summer camp, nature-center field trips, or homeschool nature days — the simple materials and engaging project make this ideal outside the traditional classroom.
• Math and measurement lesson: Use the sundial project to practice measurement, angles, time estimation, compass use (if you add direction), and observational recording.
