Can you tell the time with your own DIY sundial? For many thousands of years people would track the time with a sundial. Make your own sundial at home or in the classroom from a paper plate and a pencil. All you need are a few simple supplies and a sunny day to get started. We love fun, hands-on STEM projects for kids!

MAKING A SUNDIAL FOR KIDS

HOW TO MAKE A SUNDIAL

There are many types of sundials, most contain a ‘gnomon’, a thin rod that makes a shadow onto a dial, and a flat plate. The first ever sundial was created more than 5,500 years ago.

The movement of the sun and shadow across the sundial is the result of Earth’s rotation on its axis. As our planet spins, the sun appears to move across the sky, when really we are the ones who are moving! A sundial works because as the sun’s position seems to move in our sky, the shadow it casts will align with lines marking each hour, telling us the time of day.

Make your own sundial with our simple instructions below and then take it outside to tell the time. It doesn’t matter which way your sundial faces if it is in full sun. An easy way to set it up is by starting it on the hour and then making a mark on the plate, at regular intervals.
