You are given six cells marked A, B,C, D,E and F. Some of these are working and some are not. Design an activity to identify which of them are working. Class 7

(i) List the items that you require.

(ii) Write the procedure that you will follow.

(iii) With the items, carry out the activity to identify the cells that are working.

Answer:

(i) Items Required: Light bulb with holder, two copper wires; cells (A, B, C, D, E and F).

(ii) Procedure: Connect the light bulb with two wires to one cell (let it be A).

If the bulb glows, the cell is working.

Repeat the process for each cell (B, C, D, E and F) as well.

(iii) Carrying out the activity: Connect two wires to each cell one by one to the bulb.

The cells that make the bulb glow are working, and bulbs not glow are not working.
