Light - Shadows and Eclipses Distance, Classroom and Blended Learning KS3

The two packs in this resource allow the same lesson to be taught to students whether they are in a classroom or distance learning at home. It facilitates hybrid learning and provides equality of opportunity for students who are unable to attend school.

The classroom resource consists of an animated 26 slide PowerPoint and 13 varied and exciting printables including a foldable, cut-and-stick and progress check. The one-page flowchart lesson plan shows where choices can be made between the printables so that the teacher can select the activities to suit the exact needs of their class.

The distance learning pack consists of a 49 slide animated PowerPoint which, not only teaches the science but also how to gain maximum benefit from distance learning. The PowerPoint has been designed to replace the teacher by providing structure, sequence, knowledge and answers. Additional worksheets, cut-outs, 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. These can be printed off by the student or provided by school. There is also a short digital test/homework which can be returned to the teacher. A shortened photocopiable PDF of the PowerPoint is provided to circulate to those pupils without computers.

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).
