Description
In this set of activities, students explore different factors related to seasonal changes.
Objectives
Students will:
• Access National Oceanic and Atmospheric Administration, or NOAA, and NASA climate data from Internet resources.
• Determine changes in average temperatures, precipitation and cloud cover over time from data.
• Relate global changes to local changes.
• Explain the relationship between the Earth and the sun.
• Model the movement of the Earth around the sun.
• Define solstice and equinox.

Habits of the Mind
Students make connections between events in their lives and the seasons of the year. One major connection relates the concept of the seasons to past observations.
Keywords: seasons, time of year, observations, history, culture, math, equinox, solstice, length of day - Kinesthetic Astronomy
Students explain the relationship between the Earth and the sun, model the movement of the Earth around the sun and define solstice and equinox.
Keywords: seasons, movement, orbits, Earth tilt, star positions, constellations, equinox, solstice - Is Grandpa Right, Were Winters Colder When He Was A Boy?
Students use historic weather information and compare current data to determine if there is a significant temperature change.
Keywords: climate change, temperature records, seasons, weather, polar ice, MY NASA DATA - Seasonal Change on Land and Water
To further understanding of the causes of seasonal change, students use visualizations to compare effects of incoming solar energy in the two hemispheres.
Keywords: solar radiation, energy budget, seasons, climate, Earth tilt, absorption, reflection, albedo
