Axial Tilt of Earth By: GregorDS |
Summary: Throughout the year, seasons come and go, but depending on where a person lives, the time of the year seasons start and end changes. This is due to the tilt of the Earth causing different parts of the earth to get different amounts of sunlight. The Earth has a tilt of 23.5 degrees and depending on where the Earth is relative to the sun, each hemisphere might be in a different season than one another. If the Earth is tilted in a way that the northern hemisphere gets more sun, then it is spring or summer there, and vice-versa.
SP2: Developing and using models
We used various online models to represent how the Earth's tilt affects when and where each season occurs in a year. We also used physical models to help give us a better understanding on what season it is based off of how much sunlight is hitting each part of the Earth at a certain point in time. This also helped us better understand the relationship between sunlight, the poles and the equator.
XCC: Scale, Proportion, and Quantity
When looking at things on an astronomical scale can be quite weird, because things so large that can barely be described by our units of measurement can fit right in the palm of someones hand. This doesn't just go for physical objects, things like years can pass in a matter of seconds. There are also problems with scaling down things that are that big, because you have to get the scale factor just right so the model wont be incorrect.
