Exploring Seasons in Earth's Orbit: A Middle School Study

This study at a suburban middle school involved 93 7th-grade students exploring Earth's orbit, focused on state standards and assessments. The students showcased improvement through pre-test to post-test, with suggested modifications for different learning levels. Reflections revealed successful comprehension among students, emphasizing the importance of reading questions carefully and studying diagrams before answering.

  1. Seasons Dena Fauber WeExcell 2007-08 Earth, Moon, Sun Systems

  2. Setting • Suburban Middle School • Campus Style • Approx. 1000 students • 93 7th graders participated • Includes 10 IEP students

  3. State Standards: 6-8 Earth and Space Science/Benchmark A 6-8 Earth and Space Science/Benchmark C

  4. Assessments • Formative • Pre-test • Season Drawings 1st attempt • Group Discussion • Summative • Season Drawings 2nd attempt • Post-test

  5. 1st Attempt

  6. Extended Response

  7. Short Answer

  8. Multiple Choice

  9. Question 2 vs. Question 4 • Question 2 asked the students to label the seasons (notice that winter is on the right) • Question 4 asked the students to identify the position of the sun and Earth when North America experiences winter. • Many students reported that they did not look at the answers for tilt… just what was the same position as winter in question 2.

  10. 2nd Attempt

  11. Suggested Modifications • Lower level students • Modeling the path the sun takes around the sun is key • Guiding the students as they move • Higher level students • Leave the experience much more open to experimentation. • Allow students to determine the position of Earth’s axis compared to the sun during revolution.

  12. Reflection • Pre-Test was eye opening. • Over-all… very successful. • Student comments of “Boy was I stupid before we learned this” were common. • Need to focus on students reading the question and studying diagrams before answering questions.
