Benchmark Question: How are shadows made?
Focus Question: How can we create a shadow?
Using a light source
(flashlight, lamp, overhead projector), students will test various objects
to see how to create a shadow. Each student will draw and label a diagram
that shows how the shadow is created, The diagram will include the
following labels: a light source, straight lines for light energy, a
blocked path, and an object and a shadow.
Extension: Students can experiment with how
changes in distance between a light source and objects affect the size of
the shadows. Students can experiment with the angle of the light source to
the object and its effects on the length of its shadow.
