What is energy that causes a change in temperature?
What is Thermal (Heat) Energy
100
What type of energy transfer occurs when a pot of water on a stove is heated on a burner?
What is electrical to thermal
100
By changing the surface over which a ball rolls, students could test the effect of which of the following? magnetism electricity rotation friction
What is Friction
100
What 2 tools would be most useful in testing how the mass of an object can affect the distance it moves with a push?
What is a balance scale and a meter stick
100
In a complete circuit, a light bulb will light up when the switch is... Open OR Closed?? And why???
What is... closed, because this creates a closed circuit, making it complete!
200
What is a force that slows or stops motion when objects rub together?
What is Friction
200
All of the following are items that would use electrical AND thermal energy EXCEPT??? flashlight, light bulb, hot plate (means on burner), & a candle.
What is a candle. (It ONLY uses thermal)
200
What would you need to do to make a ball go faster down a slide?
What is... increase the slope of the slide
200
All of the following objects are conductors of electricity EXCEPT... (and why?) an aluminum nail, a rubber band, a copper penny, and steel fork
What is a rubber band (it is the only item not made of metal)
200
In a complete circuit, a light bulb will light up when the switch is closed. Draw what a closed circuit looks like.
What is... all of your parts of the circuit should be connected!!! You can check the front whiteboard for an example of a closed circuit.
300
What is a pathway that allows an electric current to flow freely.
What is a closed circuit
300
What form of energy does a bow and arrow demonstrate?
What is Mechanical Energy
300
How does gravity help keep the planets in orbit around the Sun? Is it because it is a pulling force OR a pushing force?
What is a pulling force
300
One difference between an electromagnet and a bar magnet is that the magnetic field produced by an electromagnet can???
What is be turned on and off
300
How do rubber gloves project electricians?
What is insulate the electrician because electricity does not pass through rubber. Rubber is an insulator thats why it insulates the electrician.
400
What is a magnetic field created by an electrical current?
What is an electromagnetic field
400
All of the following objects are used to produce heat or light energy EXCEPT??? lamps, ovens, bicycles, and candles
What is bicycles
400
A student was testing how far a wind-up toy would travel across a surface. Here are the surfaces tested: carpet - traveled 5 cm gravel - traveled 3 cm tile floor - traveled 7 cm What conclusion could be made about the data collected?
What is... wind-up toys travel farther on smooth surfaces.
400
When electricity flows in a complete path, it can produce what?
What is a magnetic field
400
Electricity will flow in all of the following EXCEPT... and include why not! an open circuit, a closed circuit, an electrical circuit, or a complete circuit
What is an OPEN circuit because "open" means that it is not connected all the way around so it can NOT flow! It is not a complete circuit.
500
What is a push or pull that causes an object to move, stop, or change direction.
What is Force
500
If you pick up a cup of hot tea, why would it be too hot to hold 10 second later after you've been holding it???
What is... heat always moves from objects that are hot to objects that are cold.
500
What causes a swing to move?
What is a push acting on a swing
500
Why does an object produce sound?
What is... it causes air to vibrate
500
