Seasons Greetings

PBS Teachers, Thirteen, Educational Broadcasting Company, INC

This activity uses a hands-on kinesthetic introduction, video segments from the Nature program Earth Navigators, and interactives to explain what causes Earth's seasons and seasonal changes. Different cities on the globe are used as examples to show how seasonal changes affect each city. As a culminating activity, students learn about seasonal milestones using video segments.

Activity takes two class periods. Additional materials necessary – possibly projector if video is shown to class.

Teaching Tips

  • The seasonal interactive notes that the animation is not to scale. Teachers should reinforce the idea of scale and ask some probing questions to reveal the differences between the scale in the interactive and the scale of the solar system in reality.
  • Assessment is not provided; the teacher may check for understanding by having students describe a particular place/time as a share-pair activity in order to predict the length of day and the temperature.

About the Science

  • Students use video segments and an interactive to develop an understanding of the relationship between seasons, temperature, the tilt of the earth, rotation, and revolution.
  • Educators should be alert to how the Seasons Interactive visual may help perpetuate the common misconception that seasons are caused by distance from the Sun, not by the tilt of the Earth on its axis.
  • Data for the Seasons Interactive is provided for the temperature of each city in different seasons. The concepts will hold even if the temperature for each city changes.
  • The source of the data is not given.

About the Pedagogy

  • Students move from a concrete kinesthetic activity exploring the relationship between seasons and tilt of the earth to a more sophisticated conceptual understanding by using a interactive.
  • Instructions are clear and worksheets are provided that support student learning.
  • The lesson is easy to use. Graphics are simple but effective.
  • The Teacher's Guide is well-done.
  • This is an activity that is appropriate for middle school or used as an introduction at higher levels.

Technical Details/Ease of Use

  • Ease of use is excellent.
