About this worksheet

Shadows are a concrete way for first graders to investigate that objects can be seen only when light is available and that light travels from a source until something blocks it. Children often describe a shadow as a thing that follows them without explaining what causes it. This worksheet asks students to identify the needed parts of a shadow setup: a light source, an object that blocks the light, and a surface where the shadow appears.

Questions compare materials that block light well and poorly, predict what happens when the light moves, and choose fair observations from a simple investigation. Support pages use direct flashlight and sun examples. Standard and challenge pages ask learners to reason about size or position changes. Encourage children to say the path: light shines, object blocks, shadow appears.

What your child will learn

  • Explain that light is needed to see objects
  • Identify how shadows form
  • Compare shadow size and position
  • Use observations from a light investigation

NGSS standard: 1-PS4-2

Worked example

A flashlight shines on a block and the block stops some light. A dark shape appears on the wall behind it.

Common mistake

Thinking a shadow appears without any light source because the room is dark.

Helpful hint

Name the light source, the blocking object, and the surface.
