QUIZ SHOW ELECTRICITY - AICLE

QUIZ SHOW.

TEACHER

We are going to do a QUIZ SHOW about  Electricity.

We will divide the class in three groups and they will try to find out the unknown words in the text. Group 1 and 2 have a text without some words, and they must ask questions to each other to find out the missing word. Group 3, without text, only listen and try to guess the word that the others groups are talking about.

Groups 1, 2 and 3 win points when they discover the word that is being discussed.

Only when the word is found out by group 3, the group which is answering the question wins points too.

Group C is formed by students with higher level in English. The main reason why the group 3 don’t have the text is to motivate the students of others group to give a good explanation to the opponent group.

Each question will be discussed no more than 3 minutes.

The Word never will be talked loudly.

TEXT

Current, potential difference and voltage

You need to know how to measure the current that flows through a component in a circuit. You also need to know how to measure the potential difference  across a component in a circuit and the voltage in a point.

Current

A current flows when an electric charge moves around a circuit, measured as the rate of flow of charge. No current can flow if the circuit is broken, for example, when a switch is open.

Measuring current

•  current is measured in amperes- often abbreviated to A
•  The current flowing through a component in a circuit is measured using an ammeter
•  the ammeter must be connected in series with the component.

Potential difference and voltage

A potential difference and voltage, across an electrical component is needed to make a current flow through it. Voltage is the electrical pressure that gives a measure to the energy transferred. Cells or batteries often provide the potential difference needed.

Measuring potential difference

•  Potential difference and the voltage is measured in volts, - often abbreviated to V
•  Potential difference across a component in a circuit is measured using a voltmeter
•  The voltmeter must be connected in parallel with the component.

GROUP A 

1)    Read the text about electricity.  What kind of information is missing? 

2)    Work with your partner / group and write questions about the missing information.

Example:  1) How can I measure the voltage? 

3)    Work with a partner from group B, asking and answering questions

4)    When you finish, check your texts to see if they are the same.
