| + | =Activity No # 1 - '''Direction of the current and magnetic field'''= |
| + | |
| + | ==Estimated Time== |
| + | 15 minutes |
| + | ==Materials/ Resources needed== |
| + | #Card board sheet with hole at is centre |
| + | #Connecting wires |
| + | #Iron filings |
| + | #Plug key |
| + | #Battery source |
| + | ==Prerequisites/Instructions, if any== |
| + | ==Multimedia resources== |
| + | ==Website interactives/ links/ simulations== |
| + | ==Process (How to do the activity)== |
| + | Take cardboard sheet and pass a thick copper wire vertically through the hole. Connect the ends of the wire to battery through switch. sprinkle iron filings on the board. switch on the battery. |
| + | ==Developmental Questions (What discussion questions)== |
| + | #what do you observe when current on and off? |
| + | #How iron filings arranged? |
| + | #What is the angle between wire and cardboard? |
| + | |
| + | ==Evaluation (Questions for assessment of the child)== |
| + | #State the law which determines the firection of magnetic field around a current carrying wire? (Right hand thumb rule) |
| + | ==Question Corner== |
