Vocab
Define closed circuit and open circuit
Double points for both
a complete pathway through which electricity flows
an incomplete circuit through which electricity will not flow
What is a component that opens and closes a circuit to control the flow of electricity in a circuit
Switch
What are insulators and what do they do in circuits?
Insulators are materials through which current cannot flow. They stop the current from moving to an area where you do not want the electricity to flow.
What are some devices that use rechargeable batteries?
Electronic devices like phones, tablets, computers, cars and buses.
What is the advantage of using two D-cell batteries versus only one when lighting a lightbulb?
The light bulb will shine brighter due to the energy source now coming from two places instead of one.
Define Conductor and Insulator
Double points for getting both
an object that makes a closed circuit and allows electric current to flow
an object that does not make a closed circuit. It does not allow electric current to flow.
What are some conductors and insulators that we used in our circuit in class?
Name 2 of each.
Conductors: Penny, steel paperclip, steel screw, steel rivet, and metal washer.
Insulators: Pencil, plastic spoon, rubber washer, wood stick, and cork.
What materials transfer electricity?
Conductors or metal.
How do switches save energy?
By turning off the device when it is not in use like with solar lights or smart switches like lightbulbs connected to Alexa.
What is the advantage of wiring two lightbulbs in parallel?
Both bulbs have a path to the D-Cell which will still lead to them to shine brighter
Define Metal
a material that conducts electric current
Which part of the wire is a conductor?
The metal part
What is energy?
Energy makes things happen. All actions are caused by energy, and energy can be found in many places. Also the ability to do work or transfer heat.
How do motion and light sensors work as switches?
The sensors turn the device on and off when there is motion or when there is light or dark.
What is a downside of having solar energy as a energy source.
The cost to install and maintain, and overcast days can lead to not producing enough electricity for your home.
Define Motion
observable evidence of energy
Which part of the wire is an insulator?
The plastic or rubber layer covering the wire. Was yellow and red in class.
What can electricity do?
It can produce light, heat, motion and sound.
What are some types of alternative energy sources that are used today?
Solar power, wind power, Geothermal power, Hydroelectric power.
What is the down side of using wind power as a energy source?
Cost, space to put them and running into day where there is little to no wind.
Define Motor
a device that produces motion from electricity
What are conductors and what do they do in circuits?
Conductors are materials that allow electric currents to flow from a source to another component in the circuit.
What is a battery?
A battery is stored energy in the form of chemical. They come in many shapes and sizes and can produce current flows that can change into light, heat, motion, and sound.
What are some ways that we can conserve electricity?
Turn off electronics when they are not in use, turn off the lights when you leave the room or home, and when opening the fridge think about what you want before you go to grab it so that you are not standing there with the door open.
Name the different parts of the circuit that we made in class?
Switch, wires, motor or lightbulb, and D-cell.
