Shadows change size during the day because of the position of the Sun. When the Sun is overhead shadows are short. At dusk and at dawn shadows are long.

The Sun appears to move across the sky during the course of the day
When we observe the sun during the day, it may seem like it is moving across the sky from east to west. However, it is actually the Earth that is rotating on its axis, causing this apparent movement of the sun. This rotation takes approximately 24 hours to complete, which is why we experience day and night.
The angle of the Sun's rays
The size of a shadow depends on the angle at which the sunlight hits an object. When the sun is low on the horizon, such as during sunrise or sunset, the angle of the sun's rays is more oblique. This means that the sunlight has to pass through a greater distance of the Earth's atmosphere before reaching the object and casting a shadow. As a result, the shadow appears longer.
On the other hand, when the sun is higher in the sky, such as during midday, the angle of the sun's rays is more perpendicular to the Earth's surface. This means that the sunlight has to pass through a shorter distance of the Earth's atmosphere, resulting in a shorter shadow.
Changing length of shadows
As the sun appears to move across the sky during the day, the angle at which the sunlight hits an object changes. This causes the length of the shadow to change as well. When the sun is low on the horizon, the shadows are longer, while they become shorter as the sun rises higher in the sky.
Relationship between the position of the sun and the length of shadows
The position of the sun in the sky determines the direction and length of shadows. When the sun is directly overhead at noon, objects cast their shortest shadows. As the sun moves towards the horizon, the shadows become longer. This is because the angle at which the sunlight hits the objects becomes more oblique.
Conclusion
In conclusion, the shadows made by the sun change in size during the course of the day because the sun appears to move across the sky. This apparent movement causes the angle at which the sunlight hits an object to change, resulting in shadows of varying lengths.
