Why Angle Changes Intensity

Winter, spring, summer, and fall—take the learning of the seasons beyond the elementary level to the middle school classroom. Curious learners begin by watching videos about the seasons and the rotation of planet Earth. Then, they...

Students explore winter adaptations and glare. For this winter weather lesson, students discuss the season of winter and how animals and plants adapt to the changing weather. Students discuss the glare off snow and make goggles for their...

Construct a Secchi disk based on procedure provided. In this laboratory skills and procedures instructional activity students demonstrate how to use the disk to measure the transparency of given solutions. They graph and discuss results.

Discover the chemistry behind the color change in leaves. The lesson narrator describes how trees must recycle nutrients in the leaves before they fall off for the winter. The video breaks down the process and highlights the chemistry of...

Students evaluate data to determine changes in length of day. They model the revolution of Earth around the sun to show changes in length of day and sun angle and illustrate how the sun angle affects the change of season.

Students explain the reason for the changes in season. In this lesson plan examining the relationship between the Earth and the Sun, students use an applet to discover how the alignment of the Earth and the Sun cause the change in seasons.

Sixth graders conduct a controlled investigation to determine the length of the sun's shadow on a fixed object (i.e., flagpole, telephone pole, etc.) over a three-day period (one day in the fall, one in the winter, and one in the...

Two hands-on activities celebrate the sun and moon autumnal equinox. First, scholars create a cairn using a shoebox, flashlight, and drawing tools to view the sun's progression. Second, learners take to the kitchen to bake mooncakes and...

Students explore the reasons for the seasons. In this season lesson,students use flashlights to demonstrate the movement of the Earth and how it influences the seasons. Students label pictures and discuss what would happen if the...
