Reflection: Developing a Conceptual Understanding Scale Model of The Sun & Earth - Section 2: Model of Sun & Earth


Making a model helps students to develop a conceptual understanding of a concept. Trying to understand something that is too big or too small can be difficult, so a model can help with that understanding.

Models are important because the world is so complex. Models can be valuable in predicting a system's behavior, like the behavioral relationship between the Sun and Earth. Models can help students make predictions. Models represent systems (solar system) under study and their interactions.

This model may seem simple, but I found that it really gives students a better understanding of our solar system and deepens their learning of the Sun and Earth. Using this model, students observed details about the Sun such as: I can see the swirling plasma, bright parts of the Sun, and different gases surrounding the Sun. When interacting with this model, one student wrote, "The scale model of the Earth and its distance are so small compared to the real size and that show us it's much bigger is real life!"

Scale Model of The Sun & Earth

Unit 6: Earth, Sun, and Moon
Lesson 5 of 12

Objective: SWBAT use a model to explore the relative size of Sun and Earth as well as the distance between them.

Big Idea: Models help us to understand a system or a process and are central to scientific investigations, doing research, and communicating information. Models have a variety of uses but most importantly are a visual tool that provides data.
