Science Knowledge Organiser: Summer One 1 2 3 4 5 6 7 What happens when you mix produces new colours of light? What does a prism do to splits it into the colours of the rainbow sunlight? What are the colours of the ROYGBIV: red, orange, yellow, green, blue, rainbow? indigo, violet How is sunlight different from sunlight contains all colours of the rainbow artifical light? How can you create "white" combine all the colours of the rainbow light? Why do some transparent (see Colour you see is transmitted, all other colours through) objects seem coloured? are absorbed Why do some opaque (non see Colour you see is reflected but all other colours through) objects seem coloured? are absorbed 20 Why do we get night and day? Why do we get summer and 21 winter? When it is summer in the 22 northern hemisphere is _____ in the southern 23 24 25 8 9 10 11 12 13 14 15 16 17 18 19 What is the biggest object in the solar system? What is the centre of the solar system? How do all of the planets move in the solar system? What objects orbit planets? What force keeps objects in orbits? How does distance effect the force of gravity? How does the mass of two objects effect the force of gravity? Why does the sun seem bigger then the stars? Why does the moon and stars seem to move across the sky? Why can we not see all the stars in the night sky? What is a galaxy? What is the universe? the sun they orbit the sun 26 27 28 their moons gravity longer distance means lower gravity bigger mass means bigger gravity because it is much closer because the earth spins on it's axis because the light from some is to dim (as they are very far away) a group of billions of stars All the billions of galaxies 29 30 because the earth spins on it's axis because the earth tilts back and forwards on it's axis towards the sun winter Describe how the particles are closely packed, regularly arranged in a solid: Describe how the particles the vibrate move in a solid: How does the movement of particles in a solid change as the vibrations get faster the temperature increases? How does the volume of a solid gets larger as particles spread out (slightly) as change as temperature they vibrate increases? Describe how the particles are closely packed, randomly arranged in a liquid Describe how the particles move over each other move in a liquid: How does the movement of paricles in a liquid change as the particles move faster temperature increases: How does the volume of a gets larger as particles spread out (slightly) as liquid change as temperature they move faster increases

What temperature should a hot room temperature object cool to? What is happening to the It is being transferred to the surroundings by thermal energy of an object as it heating cools? a material where heating raises it's temperature What is a thermal conductor? quickly a material where heating raises it's temperature What is a thermal insulator? slowly How does heating by heating causes particles to vibrate, vibrations conduction occur? spread along conductor How does a insulator slow stops energy transfering to surrounds as heat cooling? How does the mass of an object (with same temperature) effect bigger mass has more thermal energy its thermal energy? How does the temperature of an object (with same mass) higher temperature means more thermal energy effect its thermal energy? What does temperature how hot or cold something it measure? How do we measure with a thermometer temperature? What is the difference between Temperature is measured in degrees, energy in thermal energy and joules temperature? What is specific heat capacity? how good at storing thermal energy a material is What is the equation for speed What can we use to 46 accurately manage speed? 45 47 What is acceleration? speed = distance / time Light gates acceleration = change in speed / time taken Acceleration is _______ if the 48 same change in speed takes bigger less time acceleration is _______ if a 49 smaller change in speed smaller happens in the same time
