Imagine you’re outside during the day, and suddenly, the sky gets dark, stars come out, and it feels cooler. You might even hear nighttime animals making sounds. Then, just as quickly, the sun comes back, and everything is normal again. What you just experienced is a solar eclipse!
A long time ago, people didn’t understand solar eclipses like we do today. They often felt scared and thought these events were signs of bad things to come. But now, we know that solar eclipses are natural events caused by the movements of the sun and the moon.
There are three main types of solar eclipses, each with its own special features:
A total solar eclipse happens when the sun, moon, and Earth line up perfectly. This makes the moon’s shadow fall on a small part of the Earth. If you’re in the right spot, the sun seems to disappear completely, and it gets dark like night.
In a partial solar eclipse, the sun, moon, and Earth don’t line up perfectly. Only part of the moon’s shadow covers the Earth, so you see a shadow on just a part of the sun.
An annular eclipse occurs when the moon is far from Earth. The moon looks smaller and can’t cover the whole sun. Instead, you see a ring of sunlight around the moon.
Solar eclipses can only happen during a new moon, when the moon is between the Earth and the sun. But they don’t happen every new moon because the moon’s orbit is tilted. This means eclipses only happen once in a while.
Solar eclipses happen regularly, with two to five occurring each year. However, total solar eclipses are less common, happening about once every 18 months. The area where you can see a total eclipse is small, so it might be a once-in-a-lifetime event!
It’s very important to never look directly at the sun, even during an eclipse, because it can hurt your eyes. Use special glasses or filters to protect your eyes. If you don’t have those, you can make a pinhole camera with things you have at home to watch the eclipse safely.
When you get ready to see the next solar eclipse, remember what you’ve learned about these amazing events. Knowing how to watch them safely will make your experience even more exciting!
Create Your Own Eclipse Model: Use a flashlight, a small ball (like a ping pong ball), and a larger ball (like a basketball) to model a solar eclipse. Turn off the lights in the room and shine the flashlight (representing the sun) on the larger ball (representing the Earth). Move the smaller ball (representing the moon) between the flashlight and the larger ball. Observe how the shadow falls on the larger ball. Can you create a total, partial, and annular eclipse with your model? Discuss with a friend or family member what you see.
Shadow Observation Activity: On a sunny day, go outside and observe your shadow at different times. Notice how the length and direction of your shadow change throughout the day. Relate this to how the moon’s shadow moves across the Earth during a solar eclipse. Draw pictures of your shadow at different times and describe how it changes. How do you think this relates to the movement of the Earth, sun, and moon?
Design a Pinhole Camera: With the help of an adult, create a simple pinhole camera using a cardboard box, aluminum foil, and a piece of white paper. Use this camera to safely observe the sun on a sunny day. Practice using it so you are ready for the next solar eclipse. Write down what you see and how the image of the sun changes. How does this method help protect your eyes during an eclipse?
