UNIT

This lesson looks at the properties of light, how to draw accurate ray diagrams and what happens to light when it meets different surfaces.

Light waves

This lesson looks at the effect of light hitting a surface and a practical to investigate this.

The electrical and chemical effects of light

This lesson looks at the law of reflection, how to draw a reflected ray accurately and a practical to demonstrate the law of reflection

Reflection

This lesson looks at properties of reflected images and the differences between specular and diffuse reflection.

Reflected Images

This lesson involves looking at the practical for drawing and measuring the angles of refraction and explaining why refraction takes place.

Refraction

This lesson looks at the function of different parts of the eye, how we see light and how pinhole cameras work.

Vision

This lesson looks at dissecting an eye to examine the parts and looking at what causes short and long sightedness and how this can be corrected.

Correcting vision

This lesson looks at the colours of the visible light spectrum and why we see objects as a particular colour.

Colour

This lesson looks at how coloured filters work and applying knowledge of light to exam questions.

Filters

This lesson recaps the main concepts of light and allows application of knowledge to exam style questions.

Review of light

In this lesson you will describe the term ‘non-contact force’ and give examples. We will look at describing the forces of attraction between the Earth and moon and the Earth and the Sun. We will then describe the properties that affect the size of gravitational forces between different objects in the Solar system


Gravity

In this lesson we will be describing how gravity varies in the solar system. We will look at calculating weight, mass and gravitational field strength on Earth and other planets and finally we will change units and express answers to a given number of significant figures.


Weight and mass

In this lesson we will look at the life and work of Maggie Aderin-Pocock. She is a space scientist, science communicator and presenter of the BBC’s The Sky at Night.

Case Study of Maggie Aderin-Pocock

In this lesson we will define a light year and explain why they are used. We will look at describing the Earth’s place in the universe and be able to describe what a star is and why it emits light.


Universe

In this lesson we will use secondary data to describe and explain patterns in year lengths in the solar system. We will describe and explain differences in day length, position of the sun and temperatures in different seasons. We are going to explain why the Earth experiences seasons, but some other planets do not.

Seasons

In this review lesson we will recall key terms, definitions and structures related to space and gravity and apply knowledge to a range of questions.
