Question

practice it!
middle school science students were given the assignment to create a model of our solar system. christina creates a 3d interactive model on a computer that includes the movement of the planets in their orbits. michael created a 2d model of the solar system on paper.
comparing the two models, determine which models limitation has the greatest impact on the understanding of the solar system?
christinas model is limited because her planets were not all the same color.
michaels model is limited because he cannot show movement of planets in their orbits on paper.
michaels model is limited because his planets were not all the same size.
christinas model is limited because her model does not have sound.

• please choose an answer

Explanation:

A model's purpose is to represent and help understand a concept. For the solar system, showing planetary movement in orbits is crucial. Christina's model limitation (planet colors, no sound) is less relevant. Michael's inability to show orbital movement on paper (a 2D static medium) severely impacts understanding as orbital motion is a key aspect of the solar system. Planets not being same - size (Michael's other option) is a minor detail compared to showing motion.

Answer:

Michael's model is limited because he cannot show movement of planets in their orbits on paper.
