4 Conductors and Insulators Conductor: a material that allows electricity to flow through itInsulator: a material that does not allow electricity to flow through it
5 Group ActivityLet’s discover what materials are conductors and what materials are insulatorsCategorize the materials as conductors or insulatorsLet's try and see!
6 What did we discover? Conductors are usually: Insulators are usually: MetalsInsulators are usually:RubberPlasticWood
7 Circuits:Circuits can be open or closedOpen Circuit: Any circuit in a break in it that does not allow for the flow of electronsClosed Circuit: a complete circuit that allows for the flow of electrons
14 Parallel Circuits Create a parallel circuit Can the electrons travel to both light bulbs?YES!Now remove one of the light bulbs.What do we create by doing this?A break in our circuitCan our electrons still travel to the other light bulb and get through the circuit?Yes! Why?Because our circuit has multiple pathways
15 Parallel CircuitA parallel circuit is an electrical circuit with multiple pathways for electrons to travel throughEnd day 3
16 Series vs. Parallel Similarities: Differences: switch, power source, light bulbs, circuit wireDifferences:a series circuit has one pathway, but a parallel circuit has two or more
17 Discussion Where do we see these circuits in everyday life? What appliances use a series circuit and what appliances use a parallel circuit?End day four
18 Electricty EnergyElectricity can be transformed into three different types of energy: thermal, radiant, and mechanicalWhat do you think are the definitions of each type?Start day 5
19 Thermal Energy Electricity can be transformed into thermal energy Thermal energy is energy that produces heatWhat electrical appliances produce heat?
20 Radiant Energy Electricity can be transformed into radiant energy Radiant energy is light energyExamples?
21 Mechanical EnergyElectricity can be transformed into mechanical energyMechanical energy is everything that runs or does a task.Examples?
22 Partner workWork with a partner to categorize your list of appliances into three categories: radiant, thermal, mechanicalEach person should do their own list – use your partner to discuss the category of each appliance
