In my science class we did an experiment to find out what causes the seasons. My hypothesis was "I think the cause for the seasons is the amount of light they get from the sun". My hypothesis was correct but I was able to get an answer in a bit more depth. The amount of light that a certain hemisphere gets is caused by the tilt of the Earth's axis because one hemisphere gets a lot of light and the other doesn't get much. That is why here in Serbia it is winter and in Australia it is summer. The southern hemisphere is pointing the sun while we are pointed away. Where we are the shadows are shorter because we don't have as much sunlight because the southern hemisphere is blocking it. When it is summer in the northern hemisphere the shadows are longer because the sun is not being blocked by anything. The weather in the equator is always practically the same.

This is a picture of the seasons
1.) When it is winter in the Northern hemisphere the equator and the southern hemisphere get the most light. When it is summer in the northern hemisphere the northern hemisphere and the equator get the most light.
2.) When it is winter in the northern hemisphere they don’t get a lot of light but the equator does. When it is summer the northpole and the equator get a lot of light.
3.) If the grid lines are bigger on the globe that means that it is far away from the sun and it is cold.
4.) I believe the part of the globe that always stays cooler is both of the poles because they are always a bit further away from the sun than the equator. The part that stayed the warmest is the equator because it stays a constant distance away from the sun, and it gets the same amount of sunlight.
5.) In summer the shadow of the tooth pick is longer because the light is up higher and pointing at it. In the winter it is shorter because the suns light come from a low angle.
6.) The squares on the globe were saying how much heat a certain gets because on the equator the boxes were square saying that it got direct sun light on the northern and southern hemisphere they were rectangles which means it gets indirect sun light.
7.) Seasons are caused by Earth’s axis. In other words how the Earth is pointing at the sun. The tilt of the Earth creates the seasons because, the hemisphere that is pointing at the sun will be summer and the part that is tilted away it would be winter. When it is spring or fall the tilt is in between the tilt for winter and summer. The part that is pointed at the sun gets more light then the one that is tilted away.
Clarification for number 3 and 4: The reason the poles are colder is because the light is less direct and so it is getting less heat from the sun.
ReplyDeleteIn the end, your conclusion about the use of this model showed that you had gained a basic understanding of why we have seasons. The Equinox remember, is when the Earth is neither tilted towards or away from the sun, but it is equally illuminated by the sun. This causes spring and fall.
Good job overall. I like the way you began this post. It made the task very clear to your audience and the image as well.
