Reflecting and absorbing sound

Shadows

Reflecting light from mirrors

How we see things

Reflections in mirrors

In the Making images unit, they will build on this knowledge to learn that white light is made of different colours that can be detected by the eye, and how pinhole cameras and lenses form clear images.

In the Light and how it travels (Y6) unit, pupils learnt that light travels in straight lines, which explains why shadows have the same shape as the objects that cast them, and objects are seen by the light that reflects back into the eye or travels directly into it from a light source.

This unit explores sound and light waves, including frequencies, echoes, reflection, absorption, and the need for a medium for sound to travel. It also compares light and matter waves, investigates light transmission and colour, and examines wave properties and effects.

Sound, light and vision

What solids, liquids and gases are made up from.

To regularly and repeatedly move back and forth.

Any way of accurately representing, picturing or imagining a scientific idea.

A disturbance that travels, like a ripple on water.

A ‘pulse’ that travels through a material caused by the vibrations of particles.

The material that sound is travelling through, that is set vibrating.

An area of space with no matter present (that contains no particles).

when a sound is heard more than once because sound waves have reflected back

materials that absorb sound reduce the vibrations of the air (as sound is easily transmitted to/through them)

describes materials that you can clearly see through because they let light pass through them

if light passes through a material, we say that material transmits light

describes materials you can’t see through at all, as these materials do not let any light pass through them

an arrow added to a diagram to show the direction that some light is travelling

an unlit area in the shape of an object that is blocking light

another way of saying ‘at 90°’ - a ‘normal line’ is at 90° to a surface

to reflect off a surface means to hit the surface and ‘bounce’ off

the angle between the incident ray and the normal when light hits a mirror

Describes something that gives out light.

Describes something that does not give out light.

Surfaces that scatter light reflect light in many directions at once.

The hole in the front of the eye that lets light into the eye.

The back surface of the eye that detects light.

this word has two meanings: 1. the process of light 'bouncing off' a surface, 2. an image seen in a mirror

describes an image that has been 'flipped' horizontally (as occurs in mirror images)
