Question

In the classroom scenario, a teacher places a lamp in the center and asks a volunteer to demonstrate how Earth revolves around the Sun. Which action should the volunteer take to give this demonstration?

A) Spin in place
B) Move in a circle around the lamp
C) Ask the teacher to turn the lamp on and off
D) Stand still while the teacher carries the lamp around the student

Answer 1

To demonstrate Earth's revolution around the Sun, the volunteer should move in a circle around the lamp. This represents Earth's orbit with the lamp symbolizing the stationary Sun.

Step-by-step explanation:

In order to demonstrate how Earth revolves around the Sun, the volunteer should move in a circle around the lamp, which represents the Sun. This action mimics Earth's orbit and helps visualize the concept of revolution. It's important that the lamp stays stationary to accurately represent the Sun's relative position, as the Earth moves around it in an elliptical orbit.

In a classroom scenario for learning about Earth's movements in space, additional demonstrations could involve the volunteer spinning in place to illustrate Earth's rotation on its own axis. Another hands-on activity could include using a ball tied to a string and swinging it around to show how an artificial satellite orbits the Earth. Similarly, observing phases of a small ball representing the Moon as it moves around the head could help students understand lunar phases.
