Every season generally lasts for approximately three months. Various conditions of the weather mark seasons. During Spring, the days are warm while the nights are cold. But things are different during the summer season when the nights are warm and the days are hot. The weather is charming during winter when both the nights and the days are cool just like the conditions are during Spring.
However, during the winter season, conditions are just the reverse of the days and nights in summer. Winter days and nights are freezing. It is the availability of sunlight in a particular region of the Earth that causes changes in seasons. The changes in the season have a significant impact on the temperatures of different places. Here, we will be grabbing detailed information on making a seasonal model for a school project.

If you are wondering how to make a winter season model or how to make a spring season model, go through the detailed example provided below. This step by step process on creating a model of seasons can help you with your school project. Students who work on this 4 seasons models assignment will understand the reason why there is the longest daylight on the same day every year.
The things you will need for this summer season project are as follows:
Styrofoam ball measuring 4 inches
Two bamboo skewers measuring 12 inches each
Brush for painting
Styrofoam ball measuring 6 inches
Modelling clay in the size of a lemon piece
Acrylic black and yellow paints
A white piece of 22 by 22 inches
The very first step that you will have to take is inserting one of the bamboo skewers through the centre of the Styrofoam ball. You will have to do this very carefully.
Now divide the modelling clay into two equal pieces and make a ball out of both the pieces. Next, try to make a stand using one of the clay ball pieces by pressing the piece against a table. Later, try inserting the skewer’s pointed edge into the stand made of the clay ball piece. It will be the same skewer that you inserted through the huge ball. The same procedure should be continued with the other clay ball piece as well, but this time the skewer will be one inserted through the smaller ball.
Now take the painting brush and colour the huge ball using yellow acrylic paint. It will serve as the model of the Sun.
You can use the black marker for drawing a line around this ball. The line should be halfway between the bottom and the top side. It serves as the equator of the Earth.
Now draw another line around the ball by starting from 1 cm to the left of the skewer serving as the top of the ball and ending it at 1 cm right of the skewer serving as the bottom. This second line represents the border between night and day on Earth.
Use the paintbrush again for painting the borderline to show night and day on the left side. This time you will have to use the black acrylic paint. It serves as the model of Earth.
Next. Take the pencil and measuring stick for drawing diagonal lines on the poster board. You will have to draw the lines from the nearby two corners till the centre on the opposite side. Cut along the lines and make it a point to keep the huge triangle centre.
The market can now be used for writing the title of the project, that is “Summer Solstice: Northern Hemisphere.” Under the title, draw the position of the Earth with the Earth’s orbit around the Sun.
Carve the upright model of Earth approximately 3 inches away from the left corner bottom of the triangle on the poster board. Now get the protractor and make it stand in the modelling clay with a skewer held vertically at an angle of 90°. The next step is tilting the skewer to the right side at an angle of 231/2°.
Now position the model of Sun on the right side of the model of Earth. You need to ensure that the model of Sun is approximately 3 inches away from the right corner of the triangle on the poster board.
This working model will help you in understanding the summer solstice in the Northern Hemisphere.
1. What Causes Seasons?
The tilted axis of the Earth causes seasons. Throughout the year, varied areas of the Earth get the direct rays of the Sun. Thus, when the Northern Hemisphere tilts towards the Sun, it is summer season there, and when the Southern Hemisphere tilts towards the Sun, it is winter season in the Northern Hemisphere. Many individuals believe that the Earth lies very close to the Sun during the summer. Thus it is scorching during that season. Likewise, they think that the Earth gets away from the Sun during winters. Therefore there is cold all around. However, this is just a belief.
2. Why is the Axis of the Earth Tilted?
Like the other planets in the solar system, the earth has a tired axis with respect to its orbit. It is considered that long ago something very strong hit the surface of the Earth and this is the reason why the Earth leans a bit instead of rotating straight up and down with its axis. The strong and big thing that hit Earth long ago is known as Theia. According to the astronomers, this tilting has occurred due to the forceful collision between the platessimals. This collision has forced them to change their axis from perpendicular to tilted.
