1. ECLIPSE ?

2. An eclipse is an astronomical event that occurs when an
astronomical object is temporarily obscured, either by passing
into the shadow of another body or by having another body pass
between it and the viewer.
An eclipse occurs at those times when the Moon moves into a
position of direct alignment with the Sun and the Earth.
There are two basic types of Eclipses
SOLAR
LUNAR

5. How To Safely View An Eclipse?
Eye safety is very important to keep in mind while
watching an eclipse. According to NASA, the best
ways to observe and understand an eclipse include
pinhole cameras or solar filters. Looking at an
eclipse with “bare eyes” can cause retinal burns.
The safest and most inexpensive method to view
an eclipse is pinhole projection.

6. How To Make A Pinhole Viewer?

7. 1. Start with a long box or tube (6 feet is preferable because the bigger the box, the bigger the
image),
2. A piece of aluminum foil,
3. A pin, like you would use for sewing
and
4. A sheet of blank white paper.
Step 1: Next cut a hole in the center of one end of the box.
Step 2: Tape the piece of foil over the hole.
Step 3: Poke a small hole in the foil with the pin.
Step 4: Cut a viewing hole in the side of the box,
Step 5: Place the piece of white paper inside the box, near the viewing hole.
Step 6: Point the pinhole end of the box at the eclipse and keep your eye on the white paper.
Remember: don't look directly at the sun! You could get really hurt!
