Exhibition About Time:)

The eclipse of the sun:

A solar eclipse occurs when the moon passes between the sun and the earth so that the sun is absolutely or partially obscured. It happens when the earth, the moon and the sun are located at the same axis.

There are two types of solar eclipses.
First, we have the full solar eclipse, which happens when the moon is not near the axis of sun-earth, therefore the moon can't block totally the sunlight.
The second solar eclipse is an annular eclipse.

That type of eclipse different from the others by appearance of shining annulus around him, instead of full hide of the sun by the moon.

Moreover, the solar eclipse confuses the animals' sense of time. Animals who act in the day behave as if the night is down, and compared to them, animals that act in the night became active.

Finally, the solar eclipse is a short and impressive event, where complete darkness prevails and the stars glow fullness.



Lunar eclipse:


A lunar eclipse occurs whenever the moon passes through some portion of the earth's shadow. It can happen only when the sun, earth, and moon are aligned exactly, or very closely where the earth between the sun and the moon.

There are three types of lunar eclipses.
First, we have the full lunar eclipse, in which all the moon is shadowed.
Secondly, we have the local lunar eclipse, in which only part of the moon is totally shadowed and the other part is partially shadowed. The last type of lunar eclipse is the lunar eclipse partial shadowed, in which part of the moon is shadowed and the other part is lighted. The type and length of an eclipse depends upon the moon's location proportionately to its orbital nodes.

Eventually, the three types of lunar eclipses we have happen when the earth is located exactly between the sun and the moon, casts shadow over the moon and shadowed him.

My vacation:)

The place I visited and I would like to describe is Eilat. Eilat is one of the tourism cities which is located at the South of Israel, it is Israel's southernmost city which is surrounded by mountains.

I was there during my summer vacation for 7 days. I traveled with my family and we stayed in a hotel.
There are many attractions for all ages. On the vacation we enjoyed a lot of different and varied activities. We played at the pool and there were comedians that came up with fun contests. We were also in the red sea and in the walkway- we bought many things and enjoyed them.

The most enjoyable attraction there was the dolphin reef. I like dolphins very much and it was a special experience to be with them.
Another attraction that we made there was "The kings city". It is located in Eilat's walkway and contains many attractions like jeeps trips, kayaks, Paintball, zoo and free fall.

In conclusion, I must say that I enjoyed very much spending time with my family, detached from all the others for a few days. It was an amazing time with my family.
