IN A SERIES CIRCUIT, IF ONE BULB BREAKS DOWN WHAT HAPPENS TO ALL OF THE OTHERS?
THEY ALL GO OFF
TRUE OR FALSE : IN A SERIES CIRCUIT THE CURRENT IS UNEVEN
FALSE
WHAT WILL HAPPEN IN A SERIES CIRCUIT IF YOU ADD MORE BULBS?
THEY WILL GO DIMMER AS IT IS HARDER FOR THE ELECTRICITY TO GET THROUGH. THE RESISTANCE OF THE CIRCUIT IS HIGHER
IS THE VOLTAGE FROM THE CELL OR POWER PACK DIVIDED BETWEEN THE COMPONENTS?
YES
WHAT IS A SERIES CIRCUIT?
A CIRCUIT WHERE THE ELECTRICITY ONLY HAS ONE PATHH TO FLOW THROUGH
WHAT IS A PARALLEL CIRCUIT?
A CIRCUIT WHERE THE ELECTRICITY HAS MORE THAN ONE PATH TO FLOW THROUGH
IN A PARALLEL CIRCUIT, IF ONE BULB BREAKS, WHAT HAPPENS TO ALL OF THE OTHERS?
THEY KEEP ON WORKING
WHY DOES THE CURRENT SPLIT UP ON EVERY BRANCH?
TO POWER ALL OF THE COMPONENTS
DOES THE CURRENT ON ALL OF THE BRANCHES ADD UP TO THE CURRENT IN THE MAIN PART OF THE CICRUIT?
YES
WHAT HAPPENS WHEN YOU ADD MORE BULBS INTO A PARALLEL CICUIT?
THE BULBS STAY BRIGHT. IT IS EASIER FOR THE CURRENT TO FLOW WITH MORE BRANCHES, BECAUSE THERE ARE MORE WAYS FOR THE ELECTRONS TO GO
TRUE OF FALSE : THE VOLTAGE IS NOT THE SAME ALL THE BRANCHES IN A PARALLEL CIRCUIT
FALSE
HOW CAN YOU REMEBER THE FORMULA FOR DENSITY
IT IS IN ALPHABETICAL ORDER
DENSITY = MASS
VOLUME
TO BE ABLE TO FLOAT, WHAT DOES AN OBJECTS DENSITY HAVE TO BE?
LOWER THAN 1G/CM3
WHAT ARE THE 2 ENDS OF A MAGNET CALLED?
'NORTH SEEKING POLE' AND 'SOUTH SEEKING POLE'
WHAT HAPPENS TO A NORTH POLE AND A SOUTH POLE ARE NEAR EACH OTHER?
THEY ATTRACT
WHAT DO 2 NORTHS OR 2 SOUTHS HAPPEN WHEN THEY ARE NEAR EACH OTHER?
THEY WILL REPEL
WHAT IS THE SPACE AROUND A MAGNET WHERE IT HAS AN EFFECT?
THE MAGNETIC FIELD
WHAT TYPE OF CANS ARE ATTRACTED TO MAGNETS?
IRON CANS
NAME 3 THINGS MAGNETS CAN BE USED FOR
SORTING OUT IRON AND ALUMINIUM CANS
HOLDING FRIDGE DOORS SHUT
IN COMPASSES THAT SAILORS OR WALKERS USE
WHICH DIRECTION DOES THE MAGNETIC FIELD OF A MAGNET POINT?
IN THE SOUTH POLE AND OUT THE NORTH POLE
WHAT IS AN ELECTROMAGNET?
A COIL OF WIRE WITH AN ELECTRIC CURRENT FLOWING THROUGH IT. THIS CAUSES A MAGNETIC FIELD
HOW CAN YOU MAKE AN ELECTROMAGNET STRONGER?
1. INCREASING THE NUMBER OF COILS
2. INCREASING THE SIZE OF THE CURRENT (BY INCREASING THE VOLTAGE)
3. USING AN IRON CORE
WHAT CAN ELECTROMAGNETS BE USED FOR?
LIFTING THINGS, USED IN ELECTRIC BELLS, RELAYS AND IN VIDEO AND MUSIC RECORDING
DURING DAY TIME WHAT HAPPENS TO THE SUN?
IT FOLLOWS A CURVED PATH IN THE SKY
WHY DOES THE SUN APPEAR TO FOLLOW A CURVED LINE IN THE SKY DURING THE DAY?
THE EARTH IS ROTATING ON AN AXIS IN ONE DIRECTION CREATING THE IMPRESSION THAT THE SUN IS MOVING IN A CURVED PATH IN THE OPPOSITE DIRECTION
WHERE DOES THE SUN RISE?
IN THE EAST OF BRITAIN
WHERE DOES THE SUN SET?
IN THE WEST OF BRITAIN
HOW LONG DOES IT TAKE THE EARTH TO ROTATE ON ITS AXIS ONCE?
1 DAY (24 HRS)
HOW LONG DOES IT TAKE FOR THE EARTH TO ORBIT THE SUN?
365 DAYS AND 1/4
WHAT IS THE EARTHS PATH AROUND THE SUN CALLED?
THE EARTHS ORBIT
WHAT SHAPE IS THE EARTHS ORBIT?
A SLIGHTLY SQUASHED CIRCLE
HOW MANY SEASONS DO WE HAVE IN A YEAR AND WHAT ARE THEY CALLED?
WE HAVE 4 SEASONS CALLED SPRING, SUMMER, AUTUMN AND WINTER
WHY DO THE DIFFERENT SEASONS OCCUR?
THEY OCCUR BECAUSE THE AXIS OF SPIN OF THE EARTH IS AT AN ANGLE TO THE SUN
WHERE IS THE NORTHERN HEMISPHERE IN THE SUMMER?
POINTED TOWARDS THE SUN
WHERE IS THE NORTHERN HEMISPHERE IN THE WINTER?
POINTING AWAY FROM THE SUN
WHAT HAPPENS TO THE DAYS AND NIGHTS DURING THE SUMMER?
THE DAYS ARE LONGER THAN NIGHTS AND THE SUN IS HIGHER IN THE SKY. THE SUNS RAYS ARE MORE CONCENTRATED SO IT FEELS HOTTER
WHAT HAPPENS TO THE SUNS RAYS IN THE WINTER?
THEY ARE MORE SPREAD OUT
