Tracking The Suns Shadow For An Entire Year

Last year (2022) my oldest grandson, needed a project to show the altitude of the sun over a period of time….if possible an entire year. However, despite living 200 plus miles apart, we both made similar “solar devices” to measure the suns shadow beginning on the Vernal Equinox (March 20th 2022) and beyond. John-Winston was living in Myrtle Beach, and I was living in western North Carolina.

As following, the photograph presents the yellow (tape) mark on the right side of the scale…the sun shadow on the 2022 Vernal Equinox. On the left side, the yellow mark, was placed on March 20th 2023. The mark in 2023, is exactly the same, as it should be.

But my grandson and I needed to prove and show this with facts….after all, this is science and it must be proven.

The blue mark (tape) was placed on the scale, and on the shortest day of the year, December 21st 2022, which is the longest shadow of the year for 2022, which shows just how far south the sun was.

The white (tape) mark was placed on the first day of summer (June 20th 2022) which shows the longest day of the year. I’m sure the longest day of the year will be exactly the same on (June 20th 2023), but again, this is science, and we’ve got to prove it.

John-Winston and I have really enjoyed working together on this project, and presenting the suns shadow for an entire year. It has been a great project indeed.

Sophie (our Dachshund) just had to get in on the fun, and Debbie was happy to bring her out for this historic event.
