An Electric Personality At the end of this science topic you will have learnt enough about electricity to build your very own working model An Electric Personality My eyes flash red My head lights up I speak in a buzz language I am holding a buzz wire game My antennae spins around My eyes light up

It is a good idea to begin collecting recycled packaging as soon as possible so that everyone has plenty to choose from when it’s time to begin your model!

Now it’s time to find out more about electricity by playing a guessing game.

This game is called “Five Lives” because each time you make a mistake you lose a life. Once you have lost all five of your lives, you are out. Some questions are easy and some are hard. Just give each question your best guess.

Each question has 2 possible answers: one on the left and one on the right. You must choose which you think is correct and stand on that side of the line. If you are wrong, you lose a life! Count the lives you have lost by holding up fingers in front of you. Hold up one finger for each life lost. If the whole class is out, then everyone is back in again! Let’s begin!

1. Electricity is a type of … power station energy

2. Electricity … Occurs naturally Can only be made by people

3. Electricity is caused by the movement of tiny particles that orbit around the edges of atoms. Each of these particles has a small negative charge. They are called … electrons neutrons

location electricity static electricity 4. Sometimes electrical energy can build up in one place. This is called … location electricity static electricity

magnetic electrically charged 5. Balloons can gather static electricity when you rub them on a carpet or jumper. These balloons will attract hair or tissue paper pieces because they have become … magnetic electrically charged

6. Lightning is caused by a build up of static electricity 6. Lightning is caused by a build up of static electricity. As rain clouds move through the sky, they rub against the air around them and generate a huge electrical charge. Eventually, when the charge is big enough, the lightning leaps to Earth. A bolt of lightning contains enough electricity to light up to 100 powerful lamps for … an hour a day

7. When a lightning bolt travels to earth, the electrons move from one place to another. This is a type of electric current. Appliances that have plugs, connect to an electric current that flows into buildings … along copper wires along nylon threads

8. Electricity travels … at the speed of sound (343 metres per second) at the speed of light (almost 300, 000, 000 metres per second)

200 inventions 2,000 inventions 9. An American called Thomas Edison conducted lots of experiments on electricity and opened the first electric power plant in 1882. He invented lots of electrical household items and many of his ideas are still being used today. Over his lifetime he made more than … 200 inventions 2,000 inventions

10. A machine that converts other types of energy into electrical energy is called … a generator a lightning conductor

11. Electricity can be made from many other kinds of energy, for example by burning coal or wood chips or by using wind, wave or solar power. If a power source will never run out, we call it a renewable energy source. Which of these power sources is not renewable? Wave Power generator Water turbine Wind turbine Solar panels Coal Power Station wind coal

batteries or cells power cylinders 12. Electricity can be stored so that it can be used in portable devices and toys. The electricity is stored in … batteries or cells power cylinders

13. People often use the word battery to describe this object, but in fact this is incorrect. A single one like this is called a … generator cell

14. When you are referring to more than one, it is called a series battery

All of them except the kite 15. Electricity is safe to use if you respect its power and always follow the safety rules, but it can be very dangerous or even deadly when these rules are broken. Which of these are dangerous? Overloading power sockets Using appliances with frayed cables Pocking things into power sockets Flying kites near overhead power lines Using electricity near water or with wet hands All of them except the kite All of them

16. Electric eels can produce an electric shock to stun their prey 16. Electric eels can produce an electric shock to stun their prey. This shock is equivalent to about … 5,000 volts 500 volts
