​Learning Objective - Know how the flow of electricity in circuits can produce light, heat, and sound.

​Question - What does the law of conservation of energy state?

​Conductors & Insulators

When it comes to working with electricity, knowing the properties of materials is important. Some materials allow electricity to pass through them freely. Others block its flow.

​

• ​Conductors - allow electricity to easily travel through them.

• ​Insulators - Prevent the flow of electricity.

Multiple Choice

Your building a solar stove so you can cook food outside.  What materials should you use to transfer the heat?

• Aluminum, copper, metals

• cardboard, paper, glass

• pokemon go cards, Jedi robe, and water bottle

• clothing

​A Path to Charge

• ​Electricty requires a closed path to flow.

• ​An electric circuit is a compelte pathway made of conductors through which electric current can flow.

​Parts of a Circuit

• ​Resistors or switches causes electric charges not to flow readily.

• ​Electrical circuits need a power source.

• ​Electric circuits convert electricity to other forms of energy like mechanical and sound energy.

Multiple Choice

Is this turned on or off?

• Off because t

• On because there's a battery

• off because the switch is open

• On because the switch is on

​Parallel or Series

• ​A series circuit only has one path to follow to and from the energy source.

• ​A parallel circuit contains two or more paths for electric charges to follow.
