Lab Objective

We will design and construct an electric house with a series, parallel, and combination circuit.

We will measure the current and voltage and calculate the power and resistance of each component of the house.

TEKS

Supporting TEKS:o Scientific Laboratory

Skills:1AB; 2A-F

• 5F: Design, construct, and calculate in terms of current through, potential difference across, resistance of, and power used by electric circuit elements connected in both series and parallel combinations

• 5A: research and describe the historical development of the concepts of gravitational, electromagnetic, weak nuclear, and strong nuclear forces

Requirements Optional Historical

Component: Each student chooses a

different famous Physicist out of the list provided

The house they build will be that famous physicist’s house

Research your scientist and learn about their contributions towards science as well as their hobbies/interesting facts

Each room must contain an aspect about the scientist that you will need to explain the significance of during questioning.

The house must be 2 stories with 4 rooms minimum

1- Series Circuit 1- Parallel Circuit 1- Combination Circuit Each circuit must have a

switch and it’s own battery.

The house must be decorated with the lights serving an actual purpose in the house.

Materials• Provided by student

Box, Cardboard, or Poster board

Batteries:Two: 9 Volt One: 1.5 Volt

Optional: Switches ($0.70)

• Provided by teacher Christmas Lights (Ask

for donations – Christmas is coming up!)

Workroom Supplies: • wire cutters ($1)• multi-meters ($5-

$10)• electrical tape

($0.50)• paper clips

(switches)

1. Construct a Basic House

• Draw an outline of a 2 story house with 4 rooms on the file folder.

• Sketch out some lamps, overhead lights, ceiling fan lights, etc. for each room.

• You can decorate with furniture later.

2. Construct a Series Circuit

• Cut and strip (at least) 2 different colored light bulbs.

• Connect as a series circuit.

3. Measure the Series Circuit

• Measure the voltage of each of the components of the circuit (including the battery).

• Measure the flowing current through each of the components.

How to Measure Voltage

To measure the voltage in a part of the circuit, the voltmeter must be placed “around” that part, i.e. “parallel”

How to Measure Current

For the current to be measured in a part of a circuit, the circuit needs to be “opened” and an ammeter added “in series” in that spot

4. Calculate the Series Circuit

POWER• Calculate the Power of

each component• Calculate the Total

Power

RESISTANCE:• Calculate the

Resistance of each component

• Calculate the Equivalent Resistance of the circuit

5. Install the circuit into the House with a

switch!

6. Construct a Parallel Circuit

• Cut and strip (at least) 2 different colored light bulbs.

• Connect as a parallel circuit.

7. Measure the Parallel Circuit

• Measure the voltage of each of the components of the circuit (including the battery).

• Measure the flowing current through each of the components.

8. Calculate the Parallel Circuit

POWER• Calculate the Power of

each component• Calculate the Total

Power

RESISTANCE:• Calculate the

Resistance of each component

• Calculate the Equivalent Resistance of the circuit

9. Install the circuit into the House with a

switch!

10. Construct a Combination Circuit

• Cut and strip (at least) 3 different colored light bulbs.

• Connect as a combination circuit.

11. Measure the Combo Circuit

• Measure the voltage of each of the components of the circuit (including the battery).

• Measure the flowing current through each of the components.

12. Calculate the Combo Circuit

POWER• Calculate the Power of

each component• Calculate the Total

Power

RESISTANCE:• Calculate the

Resistance of each component

• Calculate the Equivalent Resistance of the circuit

13. Install the circuit into the House with a

switch!

14. Research your scientist!

15. Be prepared to Answer Questions about the Circuits!

Interview Questions

Reflection• How does this project

address the different aspects of TEKS 5F?

• What changes would you need to make in order for this project to work in your classroom?

• How can this project be differentiated for different types of student populations, i.e. special education/Pre-AP/AP?
