Light - Shadows and Eclipses Wildcard and Snap Card Games KS3

A great way to consolidate learning on shadows and lunar and Solar eclipses with this pack of cards which can be used to play two games – wildcard and snap. So much fun, students don’t even realise they are learning!

Prior Knowledge Required

• The shadow of a point source only has an umbra, but the shadow of a large point source has an umbra and a penumbra.
• If the light source moves closer to the object, the shadow gets bigger.
• If the object moves closer to the screen, the shadow gets smaller.
• A lunar eclipse happens when the Earth stops all, or some, of the Sun’s light from reaching the Moon.
• The Moon orbits the Earth once every 29.5 days.
• When the entire moon passes through the Earths penumbra it appears slightly darker (penumbral eclipse).
• If only part of the moon passes through the Earth’s umbra it is a partial eclipse.
• A solar eclipse happens when the Moon stops all, or some, of the Sun’s light from reaching the Earth
• A person on Earth, standing in the Moon’s umbra will see a total solar eclipse.
• A person on Earth, standing in the Moon’s penumbra will see a partial solar eclipse.
• When the Moon is at its furthest point from Earth, it no longer covers the whole surface of the Sun, and an annular eclipse is seen from the umbra.
• The Moon’s orbit is angled relative to the Earth, so the Sun, Earth and Moon are not often in the alignment needed for a lunar Eclipse to occur.
• When the entire moon passes through the Earths umbra it appears red due to refracted red light (total or umbral eclipse).
