Seasons Change
Posted by Carlene GordonSeasons change, but do you know why? In fourth grade science class, we have been studying the why. Models of globes were presented with a lightbulb to represent the sun. Student volunteers marked where we are in Connecticut and also the southern hemisphere. Then students were left with the questions, “Why do we have seasons?” and “Why do we have day and night?” After some trial and error, excellent queries as to Earth’s proximity to the sun, diagrams on the board and finding just the right tilt of the Earth’s axis a solution was found. Students worked together to determine that the revolution of Earth around the sun in an elliptical pattern of orbit combined with the tilt of the axis are the reasons behind our seasons while, the rotation of Earth on its axis provides us with day and night.
