Electricity, Conductors, and Insulators and Classifying Matter
Forms of Energy
Experimenting with Forces
Changes From Heat and Mixtures and Solutions
100
A material that prevents an electrical current or heat from flowing.
What is an insulator?
100
This is a pathway that prevents an electric current from flowing freely or stops the flow.
What is an open circuit?
100
A ball sitting at the top of a hill or a cup sitting on a table is an example of this type of energy.
What is mechanical energy?
100
This is a push or a pull that causes an object to move, stop, or change direction.
What is force?
100
This happens when water vapor in the air loses heat.
What is condensation?
200
Wood, glass, plastic, rubber are examples of these.
What is an insulator?
200
A magnetic field created by an electrical current. It is like the nail with the wire attached to the ends of the battery.
What is an electromagnetic field?
200
This type of energy is produced by vibrating objects, like music or our voice.
What is sound energy?
200
This is the force that pulls objects toward the center of the Earth.
What is gravity?
200
This happens when water molecules escape the surface of the earth due to heat entering the atmosphere.
What is evaporation?
300
A material that allows an electrical current or heat to flow through easily.
What is a conductor?
300
________________ scale measures weight or force and ________________ measures the mass of an object.
What is spring scale and balance?
300
This is seen by the eye and stored for use. Examples of this are tv and light bulbs.
What is light energy?
300
The pushing or pulling force produced by a magnet.
What is magnetism?
300
This is what is caused by the liquid in a cup when the ice cubes melt in a drink.
What is thermal energy?
400
Metal, copper, aluminum, and salt water are examples of these.
What is a conductor?
400
Mass, state of matter, look, touch, see, smell, taste and density are considered this.
What are the physical properties of matter?
400
This is the type of energy that is produced by the movement of electrons an requires the object to be plugged into an electrical socket.
What is electrical energy?
400
This is caused by movement over a surface. For example, carpet would make an object move slower.
What is friction?
400
This is a combination of two or more different substances that keep their own properties. The substances that are mixed together do not react chemically and do not form a new substance.
What is a mixture?
500
A pathway that allows an electric current to flow freely.
What is closed current?
500
This attracts things like iron, nickel, and paper clips. The ore paper clips it attracts, the stronger it is.
What is a magnet?
500
This is the type of energy that has internal kinetic energy due to the movement of its molecules. It produces heat.
What is thermal or heat energy?
500
This force can be tested by dropping things from different heights.
What is gravity?
500
This occurs when two substances are put together and one dissolves into another.
