(20 minutes)
Materials:
1 flashlight bulb
1 dry cell (1.5 V)
1 25cm insulated wire with end scrapped (or alligator wire)
What to do:
Part A.
1. Using the materials, arranged a circuit to light a bulb
2. Arrange the circuit as many as you can
3. Draw the diagram of the circuit you have just constructed and label it
4. Compare your circuit with other group
5. Note: use only one wire to light the bulb
D. Discussing new EXPLORE
concepts and Activity B.
practicing new skills What’s Inside the Circuit?
#1
E. Discussing new Using Phet Simulation, try to manipulate the icons and construct your own model
concepts and of electric circuit. Try to trace the direction of the flow of charges in the circuit.
practicing new skills
#2 (15 minutes)
What to do:
Try stretching the hose over a flat surface. Initially, insert the marbles inside the
hose and label the positions of the marbles. Now place an additional marble on one end
of the hose. What do you notice? The marble on the other end moved, right? In other words,
the marbles “flowed”. This flow of marbles is analogous to the flow of electrons.
Before an electron moves from one place to another in a conductor, it needs to be
displaced by another electron.
Now, what should you do if you want a continuous flow of the marbles? One way is
to catch the marble that exits on one end and insert it again in the other end of the
hose. Surely, this is very laborious! There is another more practical way. Try creating
a loop using the hose, that is, connect the two ends of the hose. Create a movement
of the marbles. What do you notice now? Have you created a never ending loop?
This is the concept of electrical circuit: if we take a wire, or many wires joined end to
end, and loop them around so that they form a continuous pathway, we have the means to
support a uniform flow of electrons without having to resort to infinite sources and
destinations. Each electron advancing in a certain direction in a circuit pushes on the one in
front of it, which pushes on the one in front of it and so on. All we need to do is maintain this
flow by continuous means of motivation of these electrons.

Activity A.
Constructing a Model of an Electric Circuit
Materials:
1 flashlight bulb
1 dry cell (1.5 V)
1 25cm insulated wire with end scrapped (or alligator wire)
What to do:
Part A.
1. Using the materials, arranged a circuit to light a bulb
2. Arrange the circuit as many as you can
3. Draw the diagram of the circuit you have just constructed and label it
4. Compare your circuit with other group
5. Note: use only one wire to light the bulb
Part B.
1. This time you add 2 connecting wires, a switch and a bulb holder
2. Create another model of an electric circuit
3. Close the open parts of the switch.
Activity B.
What’s Inside the Circuit?
Direction:
Using PhET Simulation, try to manipulate the icons and construct your own model
of electric circuit. Try to trace the direction of the flow of charges in the circuit.
Using the three basic principles/quantities of electricity, illustrate the relationship of electrons
or more specifically known as the charges to each one of it. Expound your idea using the
concept map below.
