The ancient Egyptians were really clever when it came to using astronomy in their buildings. They had a great understanding of the stars and the sun.

1. How They Built Their Structures:

   • Let’s look at the Great Pyramid of Giza. It was made so precisely that it points almost perfectly to true north, just 0.067 degrees off!
   • Many temples were designed to align with the sun as it rises and sets. For instance, the Temple of Karnak was built to catch the sun’s rays during the winter solstice.

2. Important Sky Events:

   • The Egyptians built their monuments to match important sky events. They created structures that aligned with a bright star called Sirius. This star becomes very bright and can be first seen in the sky around July 19. When it appeared, it meant that the Nile River would soon start to flood.

3. Keeping Track of Time:

   • The ancient Egyptians also made a special calendar. Their calendar had 365 days divided into 12 months, each with 30 days. They added a short extra month to help keep track of important astronomical events.

These examples show just how smart the ancient Egyptians were in using science to create amazing buildings.
