Lunar Eclipse

Lunar Revolution- Lunar Revolution is when the moon revolves around earth on its orbit.
Phases of the Moon- The moon changes its visual shape over the 27 day or one month. There are 8 phases of the moon.
Umbra-Dark part of the shadow.
Penumbra-Light part of the shadow.
Total Lunar Eclipse- Total lunar eclipse is when moon enters earths shadow. It happens only on full moon.
Partial Lunar Eclipse- Only part of the moon is into the earths shadow.


Summary
It takes 27.3 days for moon to REVOLVE around earth, but somtimes moon gets behind earth and gets covered with earths shadow.LUNAR ECLIPSE only happens on full moon. There are two different types of LUNAR ECLIPSE. First one is TOTAL LUNAR ECLIPSE, and second one is PARTIAL LUNAR ECLIPSE. TOTAL LUNAR ECLIPSE is when the moon totaly covered with earths shadow. PARTIAL LUNAR ECLIPSE is when only half of the moon is covered with earths shadow. There two different types of shadows first one is UMBRA and second one is PENUMBRA. UMBRA is the dark part of the shadow and PENUMBRA is the light part of the shadow.



Critical Thinking Question.
      Revolution and earths tilt causes earth to have seasons. It takes 365 days for earth to make one complete circle around the sun. When the sun, moon and earth are on a line its spring tide. When they are forming a right angle its neap tide.Also when the earth is close to the sun its equinox and when its far away its solciste.
Reflection.
1.I realy liked working with group, it was fun and it made the work 2x faster.
2.The most hard part of the project was video we had to make everything match.
3. One improvement i would make is i would rap or add some more details.
