Teacher notes;Total Eclipse;Project geography
* Use the poster to explain how a solar eclipse occurs, and what children can expect to see on August 11. Note that if they are out of the zone of totality shown on the map on the poster, they will not see anything very spectacular.
* Reinforce the safety code published on the poster and in the project. It is natural to look away from a bright light, of course; but this does not preclude the risk of eye damage.
* Use the opportunity to teach children about the relative size and predictable movements of heavenly bodies; how the Sun appears to move across the sky, giving us day and night; that the Moon has no light of its own; and that the shadow cast by the eclipse results from light travelling in straight lines.
