Fun and Educational DIY Activities to Teach and Explore Static Electricity
Introduction:
Hello, high school teachers and homeschooling parents! Are you searching for hands-on activities to engage your students or children while teaching them about static electricity? Look no further! In this blog post, we will introduce four exciting DIY activities that will captivate learners and demonstrate the wonders of static electricity. These activities are designed to be interactive and informative, allowing students to experiment and observe static charges in action. Let's dive in and electrify our learning!
Static electricity
Electricity is a branch of physics concerned with properties & movement of electrically charged particles. Static electricity is the accumulation of electrical charges on the surface of a material, usually an insulator or non-conductor of electricity. It is called ‘static’ because the electric charges are held at a place instead of flowing through. Some instances of static electricity:
Things to take care in static electricity activities
- Whenever it is asked to rub two materials make sure they both are dry.
- Make sure there is no oil in your hair. Look for a friend who hasn’t applied oil!
- If you are not getting results, rinse the testing material with water and dry it.
- Thouctivity works best when done in conditions Summer’s
Activity 1: Creating Static Charges Materials:
Materials Required:
- PVC pipe
- Scotch-Brite pad

Procedure:
- Take the PVC pipe and rub it vigorously with the Scotch-Brite pad for approximately 30 seconds.
- Hold the charged PVC pipe close to small pieces of paper or confetti.
- Witness how the static charge attracts and repels the lightweight objects.
- Engage students in a discussion about the nature and behavior of static electricity, emphasizing its connection to light and other phenomena.
Static electricity forces:
All matter is composed of atoms. An atom is composed of a positively charged nucleus surrounded by negatively charged electrons. The body is neutral when there are enough negatively charged to just balance the number of positive charges in the nucleus. Static electric charges are of 2 types: positive and negative. There is a force of attraction between opposite electric charges and a force of repulsion between the same type of electric charges.
Activity 2: Static Spinner
Materials Required:
- T joint
- Hard straw
- Foam disc
- Toothpick
- Fat straw
Materials image (remove this text )
Procedure:
- Insert a toothpick into the foam disc, ensuring a small portion protrudes.
- Cut and attach the hard straw to the T joint, ensuring a secure connection.
- Place the foam disc with the toothpick onto the protruding end of the straw.
- Rub the fat straw and put it near to set the foam disc spinning.
- Observe the mesmerizing visual effects created by light and reflections during the spinning motion.
Detection of static electricity:
The most common static electricity detector is the Electroscope. Let us make an electroscope to detect the presence of static charges on the surface of a material.
Activity 3: Making an Electroscope
Materials Required:
- Foam piece
- Hard straw
- Transparent sheet
- J metal rod
- Aluminum tape
- Aluminum strip
- Balloon
- Thermocol balls
Materials image (remove this text )
Procedure:
- Cover the thermocol ball with aluminum foil tape
- Insert a hard straw into J joint rod then insert the thermocol ball
- Keep the J joint in the rectangular foam piece
- Cut a small rectangular window from the transparent sheet and tape it to the top of the J rod.
- Affix an aluminum strip vertically to the J rod.
- Inflate the balloon and rub it against your hair or clothing to generate static electricity.
- Bring the charged balloon close to the aluminum strip and observe the movement of the thermocol balls, indicating the presence of static charge.
Tribo – Electric Series
When two objects are rubbed together, both objects acquire static charges due to friction during rubbing. One of the objects would acquire positive charge and the other one would acquire negative charge. This happens because of transfer of electrons between the two objects. The type of charge an object would acquire after rubbing with another object is given by TRIBO-ELECTRIC SERIES.
Activity 4: Making a Polarity Finder
Materials Required:
- Thin square foam
- Aluminum tape
- Hard straw
- Small foam circle piece
- Double-sided tape
- LED bulb
Procedure:
- Attach the LED bulb to the small foam circle using double-sided tape.
- Cut a strip of aluminum tape and adhere it to one side of the foam square.
- Cut a strip of aluminum tape and adhere it to one side of the foam square.
- Attach the foam square to the hard straw using tape, ensuring the aluminum tape faces outward.
- Rub the hard straw and place it near the Led bulb ends
- Activate the LED bulb and hold it near the aluminum tape.
- Observe the reflection and illumination of the surrounding area, indicating the presence of polarity.
Real Life Connect: Electric sparks
What Is a spark? A static electricity spark is a sudden flow of electric charge across an air gap, heating the air 10 high enough temperatures to cause it to glow. The size of the spark depends on the separation of the sources of electrical charges and their potential difference in voltage. A spark may be only a few millimeters, several meters or even kilometers in length. The amount of heat and noise created depend on the size of the spark.
