2.2.1 Electrical Energy

Objectives

• Compare and contrast conductors and insulators

• Describe static electricity

Electricity Review Game

​Let's review

I will put the link in the chat

Electricity is a type of kinetic energy

Electricity is caused by the transfer of electrons from one atom to another.

The movement of electrons is what makes energy kinetic.

​Electricity video p. 2 in edio

Multiple Select

According to the video, which of these naturally contain electricity?

Choose two.

• your heart

• Styrofoam

• lightning

• water

Electric Current

Electric current - the flow of charged particles, often through a wire.

Electric currents occur when electrons flow along a path from one place to another.

Electric currents power devices in your home such as light bulbs, your refrigerator, and your computer.

​ Load - device
that functions
when electric current
passes through it

Electron flow Conductor

Draw

Which of the following BEST explains why an electric current is a type of kinetic energy?

Circle the correct response.

Nudge your noggin'

These are all examples of ___ ______?

Static Electricity

Static electricity - an imbalance of positive and negative charges.

• Static electricity stays in one place.

• At most, static electricity can jump (discharge) one time.

• When it discharges, it produces a shock that you can hear, see, and/or feel.

​Lightning explained...

Multiple Choice

Which is the best example of static electricity

• using laptop on battery power

• charging phone using a charging cable

• turning on a light that is plugged into the wall

• hair standing up after rubbing it with a balloon

To summarize part 1 of our lesson...

Electric currents and static electricity are two types of electricity.

• An electric current in the flow of electrons along a path.

• Static electricity is the buildup of charges in a specific spot.

Part 2 of lesson: Insulators and Conductors

Some materials can affect how well electricity flows.

• A conductor is a material that allows electricity to flow easily.

• An insulator is a material that prevents the flow of electricity.

Definition:

conduction: the transfer of electrical energy between objects

Think about what makes a good conductor and a good insulator. Remember, no material is a perfect conductor or a perfect insulator. Some materials are better at transferring electrons than others.

Scientists use the word conductor to refer to materials that are better than average at conducting electricity.

Insulator

​The video below reviews conductors and insulators while explaining how to avoid getting a shock when you get out of a car.

As you view the video, pay attention to how the behavior of electrons produces a shock.
