Activity-1
Time: 10 minutes
Resources: 3V Coin cell, 9V Battery, 3LEDs, Male to male jumper wires, Male to female jumper wires, Female to female jumper wires, Capacitors, Resistors
Activity:
Activity:
1. Place the components under resources in their designated places on the sheet below
2. Denote the +ve and –ve end of the components wherever applicable.
Activity-2
Time: 20 minutes
Resources: For a group of three (Transparent straw, small thermocol balls, water).
Activity:
1. Take a straw and pour water inside the straw.
2. Observe the flow of water.
3. Now take some thermocol balls and add it inside the straw.
4. Now pour water inside the straw and observe the flow of water.
5. Answer the questions below based on your observations.
Activity-3
Time: 30 minutes
Resources: For a group of 3: 3V Coin cell, 9V Battery, 5 LEDs, 1m single strand wire.
Activity:
1. Attach the +ve leg of the LED to the +ve terminal of coin cell and –ve leg to the –ve terminal of the coin cell.
2. Let's make two circuits.
3. For the first circuit: as shown in the fig. below for circuit 1. Take more LEDs and connect the +ve end of all LEDs to one wire and the –ve end to the other wire and connect to the battery and observe
4. For the second circuit: as shown in the above circuit second one - Now connect the +ve end of LED to the first wire and connect the –ve end of the same Led to the +ve end of the second Led to make a chain of connection. Connect the –ve terminal of the last LED to the second wire. Now, connect the first wire to the +ve terminal of the coin cell and the second wire to the -ve terminal of the coin cell and observe the changes.
5. Answer the below questions based on your observations.
