Year 4 Science Assessments Objectives covered: Recognise that living
things can be grouped
in a
variety of ways Explore and use classification keys to help group, identify and name a
variety of living
things in their local and wider environment Recognise that environments can change and that this can sometimes pose dangers to living
things Describe the simple functions
of the basic parts
of the digestive system
in humans Identify the
different types
of teeth
in humans and their simple functions Construct and interpret a
variety of food chains, identifying producers, predators and prey Compare and group materials together, according to whether they are solids, liquids or gases Observe that some materials change state when they are heated or cooled, and measure or research the temperature at which this happens
in degrees Celsius (°C) Identify the part played by evaporation and condensation
in the water cycle and associate the rate
of evaporation with temperature Identify how sounds are made, associating some
of them with something vibrating Recognise that vibrations from sounds travel through a medium to the ear Find patterns between the pitch
of a sound and features
of the object that produced it Find patterns between the volume
of a sound and the strength
of the vibrations that produced it Recognise that sounds get fainter as the distance from the sound source increases Identify common appliances that run on electricity Construct a simple series electrical circuit, identifying and naming its basic parts, including cells, wires, bulbs, switches and buzzers Identify whether or not a lamp will light
in a simple series circuit, based on whether or not the lamp is part
of a complete loop with a battery Recognise that a switch opens and closes a circuit and associate this with whether or not a lamp lights
in a simple series circuit Recognise some common conductors and insulators, and associate metals with being good conductors
One
of the great
things to come out
of the user - generated side
of things is that this gameplay is used
in all
different ways, you may not even see your sackboy and it may not even feel like your sackboy is even there, it could be your sackboy playing a large user - created tetris or pinball game - the huge
