Science at key stages 1 and 2    (Year 1)

• describe how they try to find something when it is dark
• recognise they cannot use their sense of sight in the dark
• state that they can see things when there is some light

• identify a number of light sources of different kinds
• make comparisons between light sources in terms of brightness or colour

• recognise that lights eg bonfires, fireworks, candles, show up best when it is dark and that they can see these because they are light sources

• recognise that a torch will enable an object in a 'black box' to be seen but that when there is no light they cannot see the object
• recognise that some torches give brighter light than others
• explain that objects are easier to see in brighter light eg this torch was brightest and I could see the toy car best

• identify changes that occur when the Sun goes behind a cloud and recognise that these are different from changes at nightfall
• explain that the Sun is a source of light even when it is behind a cloud
• explain why it is dangerous to look directly at the Sun eg you mustn't look at the Sun because it's very bright and burns your eyes

• recognise that a shiny object needs a light source if it is to shine
• explain that a shiny object doesn't shine in a dark room
• say whether they expected the reflective strips to shine near a light source

• produce a collage or picture which makes a clear distinction between night/day or dark/light
