Rotation & Revolution

VOCABULARY
Axis axe:  the imaginary line through the middle of earth.
Tilt/incliner: earth tilt is 23.5 degree.
Polaris/polaris:  is the northern star earth axis point to it.
Equator/equateur:  the line that divide the earth into two equal part
Hemisphere/hemisphere:  there are two hemisphere the northern and southern.
Rotation /rotation: earth rotate on it axis
Revolution/ revolution: is the earth movement around the sun.
Orbit/orbite:  is the path the earth take around the sun.
Ellipse/ ellipse: is the shape of an orbit.

SUMMARY
The Earth axis is the imaginary line through the middle of earth which always point to the Polaris star. The earth tilt is 23.5 degree, the equator divide the earth into two equal hemisphere. Earth rotate on it axis. Revolution is the earth orbit around the sun and ellipse is the shape of an orbit.




CRITICAL THINKING QUESTION
How is earth affect by movement (revolution)?
Earth revolution takes 365 days or 1 day and earth rotate on it axis. Neap tides occur because of the movement of earth. Earth revolution causes four seasons which are spring, summer, autumn and winter.we have summer/winter solstices and equinox because the earth revolve around the sun so it receive sunlight when it is in different position or angle.




Reflection
1) What did you enjoy most about this project and why?
I enjoy working on the props such as the moon, and moving the props around for the video because I was having fun while I was doing it.
2) What was the most challenging for you during this project and why?
the most challenging part for me in this project was to figure out which thing goes first because I was really confused about what goes first or last.
3) What new skills did you learn from this project?
I think the new skills I gain through this project might be the fact that I should be organized when doing the video and just know when to bring in or out the props.
4) Is there anything that you could have done to improve any of your work? Explain.
I think we all should of looked at the video more than 3 times to give feedback so we could improve it and also get more time.
