Start (Beginning of the lesson)

Today we will have the lesson game work and power of electric current

rules:

Divide into teams

Choose the leader (captain)

Choose the title : proton, electron, neon.

Fulfill the task.

Then throw the dices and move your chip along the map.

Winner gets the prize.

Middle of the lesson

1 task. Match the letter unit and quantity.

2. Find the mistake:

7. Power is time divided by work.

8. Current is charge divided by time.

9. Ammeter is the device for measuring voltage.

10. We connect voltmeter in series in a circuit.

11. Current is directly proportional to resistance and inversely proportional to voltage.

12. Electric current is the directed motion of neutral particles.

3. Solve the mixing word task.

4 . Who is in the portrait? Choose the person and say main facts about him.

5 task. Turn on the light diode and tell the colour of it. You have battery, light diodes.

6 task. Make a circuit with rheostat, ammeter, voltmeter and battery.

7. Find work and power of your circuit
write down given, solution.

8 task. Go through the maze.

End ( of the lesson)

Do you like the lesson? Write your opinion and stick in the board.
