Let's have some fun with SCIENCE. Firstly, we will need to become familiar with some scientific terms. We will then better understand the Laws of Nature and the Ways of GOD. Also, remember to get your parents to help.

 

Let's have some more fun with

  DIRECTIONS and finding your way in the STARS.

 

Psalm 147:4

He telleth the number of the stars; 

he calleth them all by their names.

 

Don't forget to ask parents to help?

 

Now, to get DIRECTIONS, let's find the BIG DIPPER. We will need to go outside and LOOK UP on a clear night. Little kids, please get your parents permission first. The picture below shows the BIG DIPPER which consists of seven (7) of the brightest stars.

The BIG DIPPER as would be seen in October in USA

We need to LOOK UP towards the northern sky. You will find the BIG DIPPER to be easily recognizable.  The BIG DIPPER is always visible on a clear night by some of the brightest stars in the form of a DIPPER as shown in the picture above. Towards the end of the year, around October, November and December, the CUP of the DIPPER, as seen from North America is pointing up towards the NORTH POLE STAR located at the tail end of the LITTLE DIPPER, also consisting of seven (7) stars. 

The two end stars of the BIG DIPPER are always

pointing at the stationary NORTH STAR

Remember, the Earth is slowly spinning around about a rotational axis. It makes one complete turn in 24 hours. For this reason, the stars will all appear to be slowly moving around in a circular motion about a stationary star that seems to be standing still. The stationary star is actually the NORTH POLE STAR. It is called the NORTH STAR and is the most important star for the purpose of navigation and for the purpose of finding one's way.

But, first we will need to find the NORTH STAR. Once we have located the BIG DIPPER, the NORTH STAR is easily found. The two stars located at the end of the CUP of the BIG DIPPER are the pointing stars. The two stars are actually lined up with the stationary NORTH STAR, sometimes called the POLE STAR located at the tail end of the LITTLE DIPPER and is always pointing at the NORTH STAR or the POLE STAR that appears to be stationary. The POLE STAR  was given the name Polaris; easy to remember because of the "pole" sound in the name. 

In the image below, the two DIPPERS are presented as Great Bears. The LITTLE DIPPER has the NORTH STAR  Polaris at his TAIL.

The Great Bears are given the Astronomical Names:

Ursa Minor and Ursa Major which means

Little Bear and Big Bear,

Little Dipper and Big Dipper

 

In the animation below, the circular motion of the stars in the BIG DIPPER is illustrated for the four different times (Seasons) of the year: February, April, July and November. A yellow arrow always points at the stationary NORTH STAR or POLE STAR located at the tail end of the LITTLE DIPPER.

Apparent Motion of the BIG and LITTLE DIPPERS

(A counter-clockwise motion)

April

July

February

November

If you could watch the sky continually for 12 months out of the year, looking up at the same time every night, say 8:00 PM, you would notice that the BIG DIPPER appears to circle about the NORTH STAR that is tied onto the tail end of the LITTLE DIPPER. This is all due to the rotation of the Earth about its imaginary axis. The apparent motion of the stars in the sky is a counter-clockwise motion, (in opposite direction of the clock's hands) due to Earth's direction of spin on its axis. Also, since the rotational axis of the Earth is tilted 23.5 degrees relative to the Earth's plane of orbit, the position of the BIG DIPPER will appear to be oriented differently at different times or seasons of the year. For instance, in November, in February, in April and in July, the celestial sky has different appearances due to the Earth's tilt and also due to the changes in the seasons (the relative positions of the sun to the celestial background of the stars). 

IMPORTANT for Children of Science: You should also know that the axis does not really exists. It is actually an IMAGINARY rotational axis about which the Earth rotates, one complete turn every 24 hours, once a 24-hour day. This knowledge would help you stand out as one of the BEST Science students! Parents, do help your kids understand this important note!

AS SEEN FROM NORTH AMERICA

In November the yellow arrow points up at the NORTH STAR, as shown in the first picture above for December.

In February the yellow arrow points to the left at the NORTH STAR.

In April the yellow arrow points down at the NORTH STAR

In July the yellow arrow points to the right at the NORTH STAR.

It is important to remember that, as seen from Europe, Africa, Asia and other place on the globe, the pointing stars will be have different orientations.

Go over this VERY IMPORTANT KNOWLEDGE for all children of faith with your brothers, sisters and your parents.

So, when you look up at the BIG DIPPER, the two end stars in the CUP always point at the NORTH STAR. The pointing stars always point continually at the stationary star, the NORTH STAR

Keep looking up at night to always find the NORTH STAR at the tail of the LITTLE DIPPER.

 

DID YOU KNOW?

Did you know that just before the Civil War, the escaped slaves used the KNOWLEDGE of the NORTH STAR to plot their way along the Underground Railroad? "Follow the Drinking Gourd" was the name of a song the escaped slaves used as secret directions to travel north as instructed by Harriet Tubman.

When the sun comes back and the first quail calls,
Follow the Drinking Gourd.
For the old man is waiting for to carry you to freedom,
If you follow the Drinking Gourd.

Drinking Gourd was actually the name given to the BIG DIPPER.
