Earth's Seasons Demonstration - Understanding Hemispheric Sunlight

This lab example illustrates how the Earth's tilt affects sunlight distribution in the Northern and Southern Hemispheres, explaining the concept of seasons. Through placements over models, students observe differences in sunlight exposure and how the axis tilt influences seasonal changes. This hands-on activity enhances understanding of why we experience summer, winter, fall, and spring. Key educational info provided includes the role of Earth's tilt, the relationship between sunlight angle and seasons, and the misconception about changing distance from the Sun.

  1. EIS Inquiry 4.1 Student Lab Example

  2. 4.1 Materials D A S C B

  3. Inquiry 4.1 #6-8When the Earth is placed over the “A” the Northern Hemisphere is tilted away from the Sun and it gets less direct sunlight than the Southern Hemisphere.

  4. Inquiry 4.1 #9-11When placed on the “B” the sunlight appears to hit both the Northern and Southern Hemispheres equally. Neither hemisphere is tilted toward or away from the Sun.

  5. Inquiry 4.1 #12When the Earth is placed over the “C” the Northern Hemisphere is tilted toward the Sun and receives more direct sunlight than the Southern Hemisphere.

  6. Inquiry 4.1 #13When placed over the “D” The sunlight appears to hit both Hemispheres equally as the neither hemisphere is tilted toward or away from the Sun.

  7. Helpful bits of info. • The Seasons are caused because the earth is tilted on its axis. • When our hemisphere is tilted toward the Sun it is summer. • When we are tilted away from the Sun it is winter. • Summer and Winter are divided by Fall and Spring when our hemisphere is neither tilted away or toward the Sun. • The seasons are not caused by a changing distance from the Sun.
