LEARN: Simple electronic circuits

Maze Challenge Learning Manual

LEARN: Simple electronic circuits This is a D.I.Y (do-it-yourself) educational science kit that provides useful knowledge about simple physics. “You'll be amazed� to learn realistic concepts of basic physical theory through exciting activities.

How it works? The maze challenge work based on some simple electronic circuit principle. Note that after you have constructed the maze challenge, no electricity is flowing through the kit yet. During the maze challenge, if your wand touches the metal wire, then the circuit will be connected . The bell rings because electricity is flowing through the circuit and activates the motor which makes the spring rod to hit the bell. Test your hand skills on the maze challenge by passing the wand through the maze from one end to the other. If your wand touches the metal wire, the bell will ring. This means you fail in the challenge. As a result, electric current flow through the circuit and thus the motor will start working and ring the bell. If the wand does not touches the metal wire, the circuit is not connected and thus no bell will be made.

Science behind electrical conductivity: This kit is mainly design for children to learn how electric circuit is connected. In this circuit, children have to connect metal wand, metal wire, Switches and Motor. So they analyze the complete circuit and their function. In this kit, they will know how wand acts as a circuit connector; also learn the function of a simple switch and how chemical energy converted into electrical energy. By this kit children will know the following things too‌ ? What is electricity? ? Where does electricity come from? ? What does electricity do?


Do you know? Electron Current vs. Conventional Current In 1752, prior to electricity being identified with the electron, Ben Franklin chose a convention regarding the direction of current flow. Franklin assumed that electrons (being assumed positive) flow from positive to negative terminals. We now know this is incorrect. The charge on an electron is negative by definition (note negative sign): (-1.6x10-19 C) The flow of electrons is termed electron current. Electrons flow from the negative terminal to the positive. Conventional current or simply current, behaves as if positive charge carriers cause current flow. Conventional current flows from the positive terminal to the negative. Perhaps the clearest way to think about this is to pretend as if movement of positive charge carriers constituted current flow. It is important to realize that the difference between conventional current flow and electron flow in no way effects any real-world behavior or computational results. In general, analyzing an electrical circuit yields results that are independent of the assumed direction of current flow. Conventional current flow is the standard that most all of the world follows. How the electric potential difference between the two opposite charge plate leads to flow electricity?


This is arrangement of charged plates would create an electric field in the region between the plates which is directed away from the positive plate and towards the negative plate. This movement of a positive test charge from the positive plate to the negative plate would occur naturally and thus lower the potential energy of the charge. The positive plate would be the high potential location and the negative plate would be the low potential location. There would be a difference in electric potential between the two locations. Now suppose that the two oppositely charged plates are connected by a metal wire. What would happen? The wire serves as a sort of charge pipe through which charge can flow. Over the course of time, one could think of positive charges moving from the positive plate through the charge pipe (wire) to the negative plate. So, the movement of electric charge in a particular direction in knows as flow of current.

Quiz 1. What happens when we change the polarity of batteries? (a) (b) (c) (d)

There will be no current flow Current flow in opposite direction Speed of flow of current will be slow There is no effect on flow of current

2. If wand is replaced by another fully plastic wand what will happen? (a) (b) (c) (d)

There will be no bell ring. Bell will be ringing slowly Bell will be ringing fast There is no effect on the bell

3.What should we do to run the motor direct (there is no manual control) (a) (b) (c) (d)


We should connect the red wire of batteries to the spring connector 6(b) or 6(d) We should connect the red wire of batteries to the spring connector 6(a) or 6(e) We should connect the red wire of batteries to the spring connector 6(c) or 6(d) We cannot run motor directly

Additional DIY Building Electric Circuits This kit contains supplies for up to 2 classes to build simple electric circuits. Materials Required ? wires with alligator clips ? light bulbs ? switches

? batteries ? light bulb holders ? Ammeter

Series Circuits Give each group of kids a set of wires, a light bulb with light bulb holder and a switch. Show them how to use the clips to attach the wires to the battery, bulb holder, and switch. Get the kids to assemble a series circuit. Show how the light bulb doesn't light up, if the circuit is broken.

Parallel Circuits Get the kids to assemble a parallel circuit. Show how if you break the circuit in one part of the parallel circuit, a light bulb in the other part of the circuit will still light up!



How to connect : Follow below steps as figure shown.

1• Install bell module (01) on the box base (03).

2• Insert spring pole (09) to the motor module and insert C-sharp plastic lock (10) to the spring pole as figure shown. 3• Install motor module (02) on the box base. Please ensure the motor module is installed at a proper position which allows the spring pole to hit the bell.

4• Install ON/OFF switch (05) on the box base (03).


5• Install battery compartment (04) on the box base (03).

6• Install 5 spring connectors (6a, 6b, 6c, 6d, 6e) on the box base (3). Narrow end down, push the spring as far as it will go.

7• Connect red battery wire to the spring connector (6c) and black battery wire to the spring connector (6b).

8• Connect one wire of the ON/OFF switch to the spring connector (6d) and the other one connect to the spring connector (6c).


9• Fix the metal wire (08) on the spring connectors (6d) and (6e)..

10• Connect the motor module to the spring connectors, red wire to the spring connector (6a) and black wire to the spring connector (6b).

11• Connect the wand (07) to the spring connector (6a).

How to play Insert 2pcs AA size batteries to the battery compartment. Turn the switch on and put the ring of the wand around the metal wire via the open area of the ring. Keep your hand steady and carefully move the ring of the wand through the metal wire. If the ring touches the metal wire, the bell will ring and you lose! Complete the maze to achieve the fastest time against your friends. Bend the metal wire to create different levels of difficulty. Please ensure the switch is off and batteries are removed from battery compartment before bending the metal wire. Ensure all wires are correctly connected to the battery terminals and spring connectors as stated in the instruction. Bend the spring connector over and insert the exposed shiny conductor part of wire into the spring connector. If the circuit does not work, make sure the insulated “plastic� part of the wire is not obstructing the connection to the spring connector, and make sure the wires are securely connected.

Warning ! Do not short-circuit the battery terminals and spring connectors. It may cause overheating. Do not lock the motor or other moving parts. It may cause overheating.
