Transcript & safety
“How can the Moon hide the Sun? It moves between the Sun and Earth, casting a shadow. A solar eclipse! Where will the shadow go next?”
Model not to scale. Never look directly at the Sun. Use only an indoor LED lamp or torch for the activity, with adult help when needed.
The cover is an illustration, not a scale diagram. During a solar eclipse, the Moon blocks some sunlight and its shadow falls on part of Earth.
NASA: eclipse backgroundBuild the idea. Then test it.
A lamp gives out light. An opaque ball can block some light before it reaches a screen.

Make the idea yours.
