Light - Shadows and Solar and Lunar Eclipses Fully Resourced Lesson for Distance Learning and Homeschool for Middle School

This is an action-packed distance learning or home school lesson on shadows and lunar and solar eclipses for middle school

This resource has been designed so that the animated PowerPoint replaces the teacher by providing structure, sequence, knowledge and answers. The worksheets, cut-out, foldable and progress check provide a familiar medium for students to develop and test their knowledge, continue to develop their literacy skills and use their creativity to organise their learning and assess their progress.

What’s Covered

> 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).
