Ingrid Hantschk & Hans Fibi02/07/20161 How to join “Electricity” for “Primary Education” Purposes CLASSIFYING EVERYDAY´S EXPERIENCES WITH ELECTRICITY

Ingrid Hantschk & Hans Fibi02/07/20162 “Suddenly Electricity doesn´t exist, the supply breaks down. Which appliances are not longer in function ? Mark them with a cross!

Ingrid Hantschk & Hans Fibi02/07/20163 CLASSIFYING ITEMS according to “RUN BY ELECTRICITY” or “WORKING WITHOUT ELECTRICITY”

Ingrid Hantschk & Hans Fibi02/07/20164

Ingrid Hantschk & Hans Fibi02/07/20165

Ingrid Hantschk & Hans Fibi02/07/20166

Ingrid Hantschk & Hans Fibi02/07/20167

Ingrid Hantschk & Hans Fibi02/07/20168

Ingrid Hantschk & Hans Fibi02/07/20169

Ingrid Hantschk & Hans Fibi02/07/ Mark the electric appliances with a cross! A lot of things and items are used in household. Mark the electric appliances with a cross! ?

Ingrid Hantschk & Hans Fibi02/07/ Connect all items run by electricity with the outlet (by lines).

Ingrid Hantschk & Hans Fibi02/07/ Electric current originates from...? Name the items, things and machines depicted!

Ingrid Hantschk & Hans Fibi02/07/ Electric current originates from...? Colour the frame of all electric sources red !

Ingrid Hantschk & Hans Fibi02/07/ Circle Street - playing with electricity The ring is connected to the battery via the red lamp. You direct the curved copper-wire with the insulated hold. The copper-wire is connected to the other pole of the battery. The final contact is connected to the battery via the white lamp. The red lamp will shine, if you touch one ring – then you have lost. If the white lamp shines you have hit the final contact- you have won the game.

Ingrid Hantschk & Hans Fibi02/07/ The Race Start Target Move the ring along the pathway made of copper-wire from start to the target as fast as you can – but you are not allowed to touch as is demonstrated on this picture. If the red lamp shines, you must start once again. You have hit the target and you have won. The time you needed is red by the supervisor. He will write your time into a table. The fastest „driver“ has won. Therefore – do a good training !

Ingrid Hantschk & Hans Fibi02/07/ Make a bulb shine... You have at your disposal the items as pictured. Explain, why the bulb shines ! 3 V wiring diagram

Ingrid Hantschk & Hans Fibi02/07/ Make a bulb shine...

Ingrid Hantschk & Hans Fibi02/07/ Which of the bulbs is able to shine? Colour it yellow! Battery

Ingrid Hantschk & Hans Fibi02/07/ This bulb does shine !

Ingrid Hantschk & Hans Fibi02/07/ Construction of a socket. This is the feature of a real socket.

Ingrid Hantschk & Hans Fibi02/07/ The bulb. socket base lightbulb filament thread Write the technical term into the correct line.

Ingrid Hantschk & Hans Fibi02/07/201622

Ingrid Hantschk & Hans Fibi02/07/ The wiring is painted directly on the poster. Switch, also called breaker.

Ingrid Hantschk & Hans Fibi02/07/201624

Ingrid Hantschk & Hans Fibi02/07/ To construct an electric current circuit. The electric current circuit is closed. The bulb shines.

Ingrid Hantschk & Hans Fibi02/07/ To construct an electric current circuit. wiring The electric current circuit is closed. The bulb shines. The electric current circuit is interrupted. The bulb does not shine.

Ingrid Hantschk & Hans Fibi02/07/ A self-made switch. A wire fixed to the clothes peg. The switch is open - you close it by pressing the clothes peg.

Ingrid Hantschk & Hans Fibi02/07/ To construct an electric current circuit. The switch is open, the electric current circuit is interrupted. Now the circuit is closed.

Ingrid Hantschk & Hans Fibi02/07/ The electric current circuit is interrupted. The electric current circuit is closed. Depress the switch. To construct an electric current circuit.

Ingrid Hantschk & Hans Fibi02/07/ To construct an electric current circuit.

Ingrid Hantschk & Hans Fibi02/07/ Check on electric conduction. Of what does the test item consist ? What do you check by it ?

Ingrid Hantschk & Hans Fibi02/07/ Testing on ? Does wood close the electric current circuit ? Does wood conduct electricity ? Does the nail close the electric current circuit ? Does iron conduct electricity ?

Ingrid Hantschk & Hans Fibi02/07/ Which of these things conduct electricity ? Wooden stick, papered “aeroplane”, aluminium-foil, plastic-spoon, iron-wire, silver-ring, metal-screw, brass-nail, copper-sheet, glass-bottle. Write all electric conductors into this bag!

Ingrid Hantschk & Hans Fibi02/07/ Human being conducts electric current! battery sensitive lamp Alu foil

Ingrid Hantschk & Hans Fibi02/07/ Water conducts electric current! very sensitive indicator battery tub (filled with water) metal plates (nails)

Ingrid Hantschk & Hans Fibi02/07/ Water and electricity - very dangerous in combination! battery very sensitive indicator Alu-foil metal plate (nail) tub (filled with water) The lamp only glows, because in this case only undangerous current exists.

Ingrid Hantschk & Hans Fibi02/07/ YOU CANNOT SEE ELECTRICITY ! YOU CANNOT HEAR ELECTRICITY ! YOU CANNOT SMELL ELECTRICITY !  BUT YOU CAN FEEL IT !!

Ingrid Hantschk & Hans Fibi02/07/ Just now he touches electric voltage !

Ingrid Hantschk & Hans Fibi02/07/ Soon he will be in contact with electric voltage !

Ingrid Hantschk & Hans Fibi02/07/ Contactingelectricvoltage this way is dangerous for two reasons !

Ingrid Hantschk & Hans Fibi02/07/ The item is in function yet ! ? Find out why it´s dangerous ! uninsulated wires patched up The wire breaks at the edge. free heated wires are prohibited ! this old plug is not permitted !

Ingrid Hantschk & Hans Fibi02/07/ Thedangerousspots are marked by an arrow ! Explainthe danger !

Ingrid Hantschk & Hans Fibi02/07/ Explain what could bear dangers !

Ingrid Hantschk & Hans Fibi02/07/ water+voltage(current)= fatal certainty Don´t use electric items (e.g. hair dryer) when having a bath ! Don´t place an electric item at the rim of a bath tub! Never touch a switch or a wall outlet !

Ingrid Hantschk & Hans Fibi02/07/ Don´t use a too powerful bulb ! Too much heat will cause a fire ! Attention ! Soon it will burn ! Dry clothes will cover the heater and Soon he will need the phone number 122 ! Why ?

Ingrid Hantschk & Hans Fibi02/07/ Keep off from high-voltage-transmissions (power lines)! Approaching high voltage is sufficient- then a spark will jump over! The kite´s fear is o.k.- he is more intelligent then his master ! It is silly and dangerous to climb on top of a railway wagon!

Ingrid Hantschk & Hans Fibi02/07/ KNOWLEDGE OF DANGEROUS SITUATIONS MAKES YOU AVOIDING THEM ! Ingrid und Hans
