When do we have the longest shadows

This happens because our planet's spin axis is tilted On June 21st, the north pole is tipped toward the Sun, and mid-day shadows north of the tropics are short. The situation is reversed in the southern hemisphere. The south pole is tipped away from the Sun, so mid-day shadows south of the tropics are longer than usual. If Shaq flew to Buenos Aires for lunch today, his shadow would stretch an impressive 11 feet 4 inches inches taller than a regulation basketball hoop.

Above : The ratio between your height and the length of your shadow in selected cities at mid-day on the two solstices: June 21st and Dec. For example, if you want to know how long your shadow would be on the first day of summer in New York, multiply your height by 0.

The tilt of Earth's spin axis not only causes shadows to expand and shrink. It's also the reason for seasons. In June, the Sun is high in the sky. Days are long, it gets hot, and we call it summer. In December, the Sun hangs low. Days are brief and cold, and we call that winter. All rights reserved. Reasons for Seasons Exploring the Astronomy of the Seasons.

Seasonal Shadows: What to Expect Students should discover that the shadow gets longer in the winter and shorter in the spring. This investigation will help students discover that hourly shadows always point in the same direction north , move clockwise, and change length.

Students begin to grasp what happens as locations on earth move into and out of the sun's light each day. Assess the degree and accuracy to which students are able to justify their explanations of the changes in shadows in relationship to the sun's daily position.
