Daytime Shadows

Have you noticed that your shadow doesn't always look the same? Our cartoon shows why shadows change during the day.

When an object (like the stick in the cartoon) blocks some of the Sun's light, it casts a shadow. The shadow always points away from the Sun. How long the shadow is depends on how low or high the Sun is in the sky. If the Sun is low, we see a longer shadow. Is the Sun is high, we see a shorter shadow.


 
This cartoon is true for the Northern half of the Earth. The shadows point North at midday. What do you think you would see in the Southern half of the Earth?

 

Try our experiment!

On a sunny day, go outside and look closely at your shadow at different times of day. What do you notice? Does it agree with our cartoon?
