When building a house, not only must the materials be strong and supportive, but they must also prevent heat from escaping or coming in, as well as reduce sound from traveling in and out. These materials are most likely —
fillers
insulators
conductors
liquids

When people go camping, they sometimes build fires. Which of the following describes the types of energy produced by fires and how they can be helpful to campers?
Light energy can be used to see at night, and thermal energy can be used for cooking and staying warm.
Thermal energy can be used for cooking and staying warm, and electrical energy can be used to scare away wild animals.
. Light energy can be used to cook food, and mechanical energy can be used to scare away wild animals.
Sound energy can be used to scare away wild animals, and electrical energy can be used to power important devices.
When a lamp is plugged in and turned on —
. electrical energy flows through the lamp, and the lamp gives off light energy, only.
mechanical energy flows through the lamp, and the lamp gives off light and sound energy.
mechanical energy flows through the lamp, and the lamp gives off electrical energy, only.
electrical energy flows through the lamp, and the lamp gives off light and thermal energy.
When cooking, why are pots made out of metal
Metal conducts heat very well.
Metal makes the food taste better.
Another material would melt on the stove.
Another material would be too heavy to use.
Which of the following shows that an electric circuit was made correctly?
Electricity would flow through half of the circuit.
The temperature of the source of the circuit would go down.
The size of the source of the circuit would get bigger.
Electricity would flow through the whole circuit.

How does this switch control the light to which it is hooked up?
. It is where the power is made that moves through the circuit when it is flipped on,
It opens and closes the circuit, and when it is closed, the light is on.
It is where the power is made that moves through the circuit when it is flipped off.
. It opens and closes the circuit, and when it is closed, the light is off.
Mr. Erikson's class is doing an experiment on conductors and insulators. Mike's group has four jars of 90°C water and gets four different materials to wrap around each jar: aluminum foil, paper towel, newspaper, and plastic wrap. The table below shows the temperatures of each jar after one hour.
Aluminum foil
paper towel
newspaper
plastic wrap
Will the light bulb light up?
No, because the circuit needs a bigger battery
No, because the circuit is too long
Yes, because the circuit is open
Yes, because the circuit is complete
Is this a complete circuit?

yes
no
Is this a complete circuit?
yes
no
