Inv. 2-1 Lighting a Bulb Date FQ: 1) How can you get electricity from a source to a receiver? 2) Where do connections need to be made? 3) How does electricity flow through a circuit? P: (IN PEN)
D-cell battery; source of electricity; more than one cell electricity source provides the energy to light the bulb electricity receiver a component that uses the electricity from the source to make something happen
circuit a pathway of the flow of electricity filament part of a bulb that gets hot & produces light components (ex.) D-cell, bulb, & wires short circuit low-resistance conductor that bypasses a component
One wire touches the side, and the bottom of the bulb touches the D-cell. light bulb light bulb D-Cell filament D-Cell wire One wire touches the side of the bulb, while the other wire touches the bottom. wire
C: A D-cell is a source of electric energy. A bulb is an energy receiver that produces light. To make a complete circuit, electricity must travel in a circle from one end of the battery to the other.

Inv. 2-2 Making a Motor Run Date FQ: 1) How can you get electricity from a source to a receiver? 2) How is the motor circuit like the light bulb circuit? 3) What does a switch do in a circuit? P: (IN PEN)
circuit base holds many components needed to build a circuit Fahnstock clip metal clip that connects wires in a circuit switch devise used to open and close circuits
open circuits an incomplete circuit through which electricity will NOT flow closed circuits a complete circuit through which electricity flows schematic diagram a way to represent a circuit on a piece of paper
Drawing of a Battery and Bulb Circuit Schematic Diagram of a Battery and Bulb Circuit
C: A motor is an energy receiver that produces motion. A switch is a device that opens & closes a circuit. Schematic drawings represent circuits.

Items that will complete the circuit: CONDUCTORS Items that WON T complete the circuit: INSULATORS
Items that will complete the circuit: CONDUCTORS Items that WON T complete the circuit: INSULATORS * water * air human copper brass ring washer shiny nail dull nail screen paper fastener aluminum foil paper clip screw * glass yarn craft stick rubber band river pebble black rock plastic chip straw sponge cardboard
conductor a substance, commonly a metal such as copper or aluminum, through which electricity will flow insulator a material that prevents the flow of electricity, commonly plastic, rubber, glass, or air
C: All metals are conductors. Metals that are covered with insulators will not conduct electricity.

Date Inv. 2-4 Investigating Mystery Circuits FQ: How would you detect where there is a mystery circuit? Explain what you would do & what you would use. P: (IN PEN)
Mystery Circuits (example) A B A B C 1 D C 7 D Some of the hidden wires were a little difficult to find. We Number 1, 3, & 6 have two wires. had to test the paper fasteners various times until we found the two hidden wires. We also found that it was difficult to keep the light bulb in its holder. So, sometimes, we had to re-adjust it before testing for circuits again.

Inv. 3-1 Building Series Circuits Date FQ: 1) Can you get two bulbs to light at the same time? Explain. 2) Can you make two lights bright in a series circuit? Explain. P: (IN PEN)
series circuit a circuit with only one pathway for current flow component an individual item in a circuit
Series Circuit Schematic Now that you have made this circuit. Lets see what happens when you add more components.
Series Circuit Schematic
C: A circuit with only one pathway for current flow is a series circuit. Components in a series circuit share the electric energy. Cells in a series circuit must be oriented in the same direction.

Inv. 3-2 Building Parallel Circuits Date FQ: 1) How can you light two bulbs brightly with just one D- cell? Explain. 2) How many different ways can you wire a parallel circuit? P: (IN PEN)
Parallel Circuit Schematics A B
Parallel Circuit Schematics C D
parallel circuit a circuit that splits into two or more pathways before coming together at the battery
C: Components in a parallel circuit each have a direct pathway to the energy source. A single D-cell can run many components when they are connected in a parallel circuit.
NOTE: * If you want more energy, put your batteries in a series circuit. * If you want the source to work longer, put the batteries in a parallel circuit.
Parallel Circuit with a switch. When putting a switch in a parallel circuit: If the switch is open the bulb lights. If the switch is closed the bulb goes out. This circuit is ON! Why? The source has 2 possible paths, one with a lot of resistance (the bulb) & one with virtually no resistance (the switch), essentially all of the current will flow through the switch. IT TAKES THE PATH OF LEAST RESISTANCE!
