Guiding Question: How does the title of Earth’s axis affect the light received by Earth as it revolves around the sun?
Hypothesis:
I think that it will have more light when either the south or northern hemisphere is facing the sun. Because it is summer at that time, depending on which hemisphere you have the June Solstice in Northern hemisphere and December solstice in the southern hemisphere. Also during summer it is hotter, more sunlight, more heat, and also longer days. And its winter when one of the hemispheres are not facing the sun. When its colder, not as much heat, and less sunlight.
Observations:
The Northern Hemisphere in summer:
-there is more light on the northern hemisphere so it is summer there, and there is less sun facing the southern hemisphere so it is winter there
- In there northern hemisphere because its summer the tooth pick has a longer shadow, but it is winter in the southern hemisphere so there is a shorter shadow
-Because the northern hemisphere is facing the sun around that time it is called the June Solstice so the days are longer in Northern hemisphere, but in the southern hemisphere the days are shorter
The Northern Hemisphere in winter:
-There is less light facing the Northern hemisphere so it is winter there, but in the southern hemisphere there is more light so it is summer there
-There is a shorter shadow in the northern hemisphere because it is winter and less light, but more light in the southern hemisphere so longer shadow there
- At this time the southern hemisphere is facing the sun so it is the December Solstice, so the days are longer in the southern hemisphere, but in the northern hemisphere the days are shorter
The North and Southern Hemisphere in spring and autumn:
-Neither the north or southern hemisphere is facing the sun so it is either spring or fall in the south or northern hemisphere
- Because there is spring or fall the shadow is in-between the short shadow and the long shadow
- At this time because neither hemisphere is facing the sun, we have this twice a year, the September and March equinox, so they have around the same temperature, and twice a year in both sides of the earth they have the same amount of hours in a day
Conclusion:
Doing this activity really helped me get a better idea of how the seasons work. Before I knew that the earth turned around the sun but I never really though about the hemisphere changing and facing the sun causing it to make seasons. What I find most interesting is when neither hemisphere is facing the sun, I find it interesting how twice during a year in each hemisphere they both have the same amount of hours during the night and day. So I really enjoyed doing this activity, I have learned a lot.
Hannah,
ReplyDeleteThe image you included was good to demonstrate what the model was supposed to show. You made excellent observations and conclusion, however the analysis is missing from the textbook section.
