This hands-on activity allows students to investigate the differences in daylight hours and the directness of the Sun's rays for both the northern and southern hemispheres, as it pertains to seasons.
Prerequisite: Students should understand that the Earth tilts 23.5º as it orbits the Sun which is the cause for seasons on our planet.
NGSS Science Standard MS-ESS1-1: Develop and use a model of the Earth-sun-moon system to describe the cyclic patterns of lunar phases, eclipses of the sun and moon, and seasons.
Disciplinary Core Idea: ESS1.B: Even though Earth’s orbit is very nearly circular, the intensity of sunlight falling on a given location on the planet’s surface changes as it orbits around the sun. Earth’s spin axis is tilted relative to the plane of its orbit, and the seasons are a result of that tilt. The intensity of sunlight striking Earth’s surface is greatest at the equator. Seasonal variations in that intensity are greatest at the poles.
