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
|
