CLASSIFYING MATERIALS

as a 1* scientist

You can describe the features based on using your senses: e.g. shiny, dull, hard, soft, heavy, light, rough, smooth, bendy, brittle, stretch, cold, hot, slimy, rubbery, colour, runny, burnt, crunchy, see-through.

as a 2* scientist

You can use the word materials e.g. (plastic, wood, etc.) You can observe and describe features of materials and sort into groups based on features like shiny, dull, hard, soft, heavy, light, rough, smooth, bendy, brittle, stretch, cold, hot, slimy, rubbery, colour, runny, burnt, crunchy, see-through.

You can spot some materials (e.g. wood, rocks, soil, etc.) that are found naturally. You can also notice that some materials have some features that are the same while other materials have different features.

as a 3* scientist

You can use the correct words without being reminded, to group different materials based upon a number of features including hardness, strength, magnetic / non-magnetic, flexibility.

You can link the jobs of an item with the material it is made of and the features of the materials (e.g. wood is hard and is fairly strong but it can be shaped and is used for building; plastic is waterproof, light, easily shaped and is used for bags, etc.)

Changing materials

as a 1* scientist

You can describe the features based on using your senses: e.g. shiny, dull, hard, soft, heavy, light, rough, smooth, bendy, brittle, stretch, cold, hot, slimy, rubbery, colour, runny, burnt, crunchy, see-through.

as a 2* scientist

You can notice that different materials (with different properties) can have their shape changed by twisting, bending, stretching and squashing.You can sort into groups based on features like shiny, dull, hard, soft, heavy, light, rough, smooth, bendy, brittle, stretchy, cold, hot, slimy, rubbery, colour, runny, burnt, crunchy, see-through.

You can also see and describe things like clay squashing, paper twisting, plastic bending, elastic stretching, ice melting, chocolate melting, wood burning, candle burning, etc.

as a 3* scientist

You can pick out some materials that change features when heated but go back to what their features were when cooled like ice melts to give you water and you can make that water into ice again. You can pick out some materials which have their features changed forever when heated like an egg cooks and we cannot get clear egg white again; wood burns; firing of clay. You also know that when salt or sugar is added to water you can still taste the salt or sugar so it is still there but it has changed.

electricity: simple circuits

as a 1* scientist

You know that some things need electricity to make them work. You can use words like electricity, switch, wire, battery (cell), safety and you know that a battery = a group of cells.You also know that when we switch something on it works and can be useful.

as a 2* scientist

You can make a circuit with a battery (or cell), wire(s) and bulb/lamp(s). You know that the wire(s) have to connect (join) to certain parts of the battery (cell) and bulb(s). The battery (cell) is a source of energy.

You can make a buzzer work by also connecting it up in a circuit. You can use words like circuit, bulb/lamp, buzzer, complete.

as a 3* scientist

You know that when you make a circuit, a break (gap) in it will stop the device working and you can use a switch to get the same thing to happen. You can draw a circuit as you see it,(battery [cell], wires bulb / buzzer, switch).

You know that a battery (cell) is needed to supply the circuit with energy and, the more cells you have the brighter the bulb or the louder the buzzer.

You also know more bulbs/lamps that are used in a single loop circuit the less bright they will be (if the number of cells is kept the same).

LIGHT

as a 1* scientist

You know that light comes from the sun, light bulbs, candles andthat we use our eyes to see with. You also know that you can see yourself in a mirror.

You know and can use words like sun, light, dark, bright, dim, morning, night, day, candle, torch, shadow.

as a 2* scientist

You know that you can see in the light but NOT in the dark and that some light must be there to see.You also know that the brighter the object, like the sun the more light there is and that some things give out more light than others.

You know that the place where the shadow is, is affected by where the light is compared to the object.You know and can use words like shiny, dull, reflect.

as a 3* scientist

You know that some materials let light go through them, some materials let a little light through and some materials let no light through. You can tell that a shadow is made because light cannot get through the material. You also know that objects look dark when there is no light falling on them.

You can use a mirror or any shiny surface to reflect light and you know that the shinier it is, the better it reflects.

You know that shaped glass can produce different colours from white light.

forces and motion

as a 1* scientist

You understand what the words push, pull, move, still, moving, fast, slow, force mean.

as a 2* scientist

You know that pushes and pulls can make things move and that some things travel faster than others.

You know and can use words like more / less force, right / left direction, slope, faster, slower, more / less speed.

You can also compare movement / speed / direction of different objects and you can use arrows to show the direction of the movement or the force

as a 3* scientist

You know that if you pull with the same force as you push the forces are balanced.

You also know that the more force you put into something the more effect it will have. You can also say what will happen when you push with a big force in one direction and a little force in the opposite direction.

You can show that the size of an arrow can show the size of force. You also know that Gravitational force is an example of a pull.

sound

You know and can use words like: sound, loud, quiet, ears, music.

as a 2* scientist

You know that sounds can be made in a variety of ways; hitting, blowing, plucking etc. and that different materials make different sounds when we hit, blow, pluck etc.

You can pick out things from the sounds they make and you know that musical instruments as a 3* scientist

You know that when a drum vibrates it makes a sound. As something vibrates more / less different sounds are made. You know that sometimes we can see a vibration but sometimes we cannot (because it happens at too fast a rate).

You also know that sounds can be reflected and this is what we call an echo.

You know and can use words like: vibration.

all make particular sounds.

You know and can use words like high, low.
