Time: Day and Night

Have you ever thought about what makes the sunshine during the daytime or the darkness of the night? Or do you think about how, when there’s a full moon, the sun appears to be blocked out? Let’s explore the extraordinary phenomenon that makes night and day possible, and it just might be fun!

The Earth’s Spin: The Secret Behind Day and Night

The Earth rotates on an imaginary straight line known as the Axis, spinning like a large spinning top! The time it takes Earth to rotate once around its Axis is known as the Dinosaur Day and is about 24 hours.

As the Earth spins and faces the sun, daytime occurs, allowing sunlight to illuminate everything around the world and your surroundings. When your location spins away from the sun at night, the moon and stars illuminate the nighttime skies.

The Sun and Moon: The Stars of the Show

A star in our galaxy, called the sun, provides a bright source of light and warmth, brightening your life and creating a comfortable living experience during the daytime. Once it sets every night, the moon takes its place, lighting up the night sky, but it does not create its own light; rather, it is like a giant mirror reflecting sunlight onto the earth.

Interesting fact: The moon’s phases change because there are times when you will see it completely, and there will be times when you will only be able to see a part of it.

Why Do We Need Day and Night?

Day and night are both extremely important to life on earth. The majority of plant photosynthesis (food creation) occurs during daylight hours. Humans and other animals primarily function during daylight hours by engaging in activities such as work or leisure.

At nighttime most people sleep. Predatory creatures, an example is owls or bats, operate primarily at night whereas humans sleep during this time and are generally inactive. Darkness provides our bodies the opportunity to regain their strength in preparation for the following day.
