Just wanted to share a great interactive site for teaching students about shadows in conjunction
with Groundhog Day.
Students will "Learn about the sun, light & shadows as you experiment with
different light sources and objects in this fun, interactive science
activity for kids. Moving a light source closer to an object can make
its shadow grow larger while moving the light source away can have the
opposite effect. Experiment and see what happens to the shadows of
different objects when you tilt the light source or change its
brightness, what happens to the shadow if the light source is dim?
Head outside and see how sunlight creates shadows with various objects
such as trees, houses and cars. Learn how the sun's position in the sky
effects the size of shadows. Even the moon can create shadows when it
reflects light from the sun. Enjoy the challenge of this cool science
game."
