Im soo confused , like is this a good example of it

No, neither image is a good example of a scale model. You need to pick an object that represents the size of the Sun in your scale model. Say, for example, a basketball (basketball's diameter is about 9.4 inches). The diameter of the Sun is 1.4 million kilometers or 870000 miles, you your basketball represents that size. Then you need to find out how far away each planet is from the Sun and the diameter of each planet as well.

Using the basketball as the Sun, you then determine you scale. If the basketball (9.4" in diameter) represents the Sun (870000 miles in diameter) your scale is about 1" = 92553 miles. This was determined by taking the Sun's diameter and dividing it by the basketball's diameter.

So, just to give you an idea of how you would continue with the exercise in math, using the above scale, how far would Earth be from the basketball? The Earth is 93 million miles away. So, 93,000,000 divided by 92553 inches per mile = 1004.83 inches away. That is 83.74 feet away. So, either you should pick a smaller object for the Sun or make your model on a football field.

AND, how big with the Earth be on that scale? The Earth's diameter is 7926 miles, so 7926 miles , divided by 92553 miles per inch = 0.086". That is smaller than a BB.

The problem with making a scale model for the solar system is that if you choose objects you can see, like a basketball, the distances between the planets are huge. If you pick objects for the Sun that you can create in a classroom, they are so small as to be microscopic, at least for the planets.

But that is how its done.

No, those are not scale models.

In a scale model, the sizes and/or distances are to scale; meaning the proportions are preserved. So for example, if the Sun has a diameter 50 times larger than that of Jupiter in the real solar system, then the model Sun has a diameter 50 times larger than the model Jupiter.
