Rotation

Vocabulary

Summary
Rotation is the movement of earth on its self. Rotation length takes approximately 24 hours to make one rotation. It also takes about 365 days to make a whole revolution around the Sun. Polaris is when the axis of earth always tilt in Polaris Star and its always in the northern hemisphere. Earth's Axis is an imaginary line across the earth. Axis tilt is when earth's axis tilted about 23.5 degrease. Hemisphere is a half of the earth (northern hemisphere and southern hemisphere). Equator is an imaginary line that divided earth into two equal parts. Some evidence of earth rotation are, Pendulum ,is a fixed point that makes it swing straight out and the force of gravity pulls it back, and Coriolis effect, are the movement of objects in the Northern Hemisphere are seems to go to the right, while objects in the Southern Hemisphere are seems to go to the left.
How is earth affected by movement (revolution)?
The moon affects Earth in many way such as tides and day-night light levels as it orbits the planet. As earth rotates its axis tilts about 23.5 degrease which causes the season. It is so important for us that earth revolves around the sun because its causes day and night.
Reflection
- What did you enjoy most about this project and why?
The most thing I enjoy about this project was taking video and record our own voice and then edit the video so we can present it to our class.
-What was most challenging for you during this project and why?
The most challenging part is that I was absent during the day that we should record our video because I was sick so I did not know if my group recorded it or what should we do.
- What new skills did you learn from doing this project?
Some new skills I learn in this project is edit videos in iMovie.
-Is there anything that you could have done to improve any of your work? Explain
If their was one thing to change is to rerecord my video because the voice was low and I wanted it to be higher
