Heat, Electricity, Sound and Light

1. The pathway through which electricity flows is called

• current
• circuit
• electricity
• conversion

2. What is a conductor?

• A change in nature, form, or units.
• A force that slows or stops motion when objects rub
• Material through which heat or electricity does not easily flow through it
• Material that allows heat or electrical energy to easily flow through it

3. What is an example of a good conductor?

• copper
• rubber
• plastic
• glass

4. Energy that allows us to see

6. Allows SOME light to pass through, but objects cannot be seen clearly

• Lightning
• Transparent
• Translucent
• Radiation

7. What is an electric circuit?

• The pathway through which electrical current flows.
• A force that slows or stops motion when objects rub together.
• Describes change in an object’s position with respect to time and in comparison to other objects.
• A change in nature, form, or units.

8. Allows ALL light to pass through; objects can be seen clearly

• electricity
• opaque
• conversion
• transparent

9. What is friction?

• A change in nature, form, or units.
• A series of small, fast movements back and forth or from side to side.
• A force or rubbing something together to create heat.
• Describes change in an object’s position with respect to time and in comparison to other objects.

10. What type of energy causes a change in temperature between materials?

• heat
