Strand V
Use Scientific Knowledge from the Earth and Space Sciences in Real-World Contexts

 

Science/Strand V
Content Standard 4
All students will compare and contrast our planet and Sun to other planets and star systems; describe and explain how objects in the solar system move; explain scientific theories as to the origin of the solar system; and explain how we learn about the universe. (Solar System, Galaxy, and Universe)

Science/Strand V/Content Standard 4/Elementary
Benchmark 2
Describe the motion of the Earth around the Sun and the Moon around the Earth.

Benchmark Clarification

The Earth travels around the Sun while the Moon travels around the Earth. This motion can be recorded on a calendar as months, years, and MoonÕs phases. The motion of one body around another body is called revolution/revolving. The path that the Earth and Moon take as they revolve is called an orbit.

Students will:

  • Describe the motion of the Earth around the Sun as revolving in an orbit
  • Explain that the motion of the Earth around the Sun follows a path called an orbit and can be measured as one year
  • Describe the motion of the Moon around the Earth
  • Explain that the motion of the Moon around the Earth follows a path called an orbit and can be measured as one month

Note: This motion is not rotation/rotating/spinning on an axis. The Earth spins on its axis once every twenty-four hours and is measured as a day or day and night. A entrenched misconception, present in college, is that rotation and revolution are synonymous. Having students spin in place and then walking around a central point are good ways to differentiate the two concepts. A fun activity is having students both spin and walk around a central point, mimicking the actual rotation and revolution of the earth around the sun.

Instructional Example

Benchmark Question: Describe the motion of the Earth around the Sun and the motion of the Moon around the Earth.

Focus Question: How does the Moon move around the Earth?

The teacher will pose the focus question.

Students, working in small groups, will design a model of how the Moon moves around the Earth.

Students will collect the materials they need and will create their models. Groups will have some time to practice how they will present their models. Teachers should avoid ÒcorrectingÓ misconceptions at this point.

Each group will present their model. After presentations, the class will discuss similarities and differences among the models. The teacher may guide discussion to correct student misconceptions through inquiry. Groups then will be allowed to alter their presentations and to make corrections. The groups then will present their models again.

Constructing: (SCI.I.1.E.1), (SCI.I.1.E.2), (SCI.I.1.E.3), (SCI.I.1.E.5).

Reflecting: (SCI.II.1.E.1), (SCI.II.1E.2), (SCI.II.1.E.4).
