Our Place in Space

The video explores the concept of space as a vacuum where gravity affects all objects. It explains how gravity governs the movements of celestial bodies in the solar system, including planets and asteroids. The Earth's rotation and revolution around the sun create the basis for time, with a day lasting 24 hours and a year approximately 365 days. The Earth's axial tilt causes seasonal changes, with different parts of the planet experiencing varying amounts of sunlight. An experiment with a flashlight and globe demonstrates how light angles affect seasons.

Describe the process of how day and night occur on Earth.

What experiment can you conduct to understand the impact of sunlight on seasons?
