What is a Conductor?
A material or an object that conducts heat, electricity, light, or sound.
100
What is the 1st type of heat and energy transfer?
Conduction
100
What is Matter?
Physical substance in general, as distinct from mind and spirit that which occupies space and possesses rest mass, especially as distinct from energy.
100
What is the first step to the Scientific Method?
To make an Objective Observation.
100
What is Newton's Laws of Motion?
Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force.
200
What is an Insulator?
A thing or substance used for insulation.
200
What is the 2nd type of heat and energy transfer?
Convection
200
What is the Change of State?
The physical process where matter moves from one state to another.
200
What is the second step to the Scientific Method?
Formulate a hypothesis.
200
What is Newton's first law?
Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force.
300
What is an example of an Insulator?
Insulators oppose electrical current and make poor conductors; so all metals have high conductivity and are good conductors, while rubber, plastic, ceramics and glass have low conductivity, making them the best insulators.
300
What is the 3rd type of heat and energy transfer?
Radiation
300
What is the Change of State of Matter?
The state or phase of a given set of matter can change depending on pressure and temperature conditions.
300
What is the thirst step to the Scientific Method?
Test the hypothesis.
300
What is Newton's second law?
Newton's second law of motion; the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
400
What is an example of Conductors?
Conductors conduct electrical current very easily because of their free electrons; so copper, steel, gold, aluminum, and brass are good conductors.
400
What does Convection and Conduction involve?
Conduction and Convection involve particles.
400
How is the Change of State of Matter used?
The state or phase of a given set of matter can change depending on pressure and temperature conditions, transitioning to other phases as these conditions change to favor their existence.
400
What is the forth step to the Scientific Method?
Establish a theory based on repeated verification of the results.
400
What is Newton's third law of motion?
A force is a push or a pull that acts upon an object as a results of its interaction with another object; these two forces are called action and reaction forces
500
How do we use Conductors & Insulators in every-day life?
Insulators are used to protect us from the dangerous effects of electricity flowing through conductors. Good electrical conductors are also good heat conductors because both forms of energy rely on free electrons to transfer through the material.
500
What does Radiation involve? And what is the heat that is used?
Radiation involves electromagnetic waves. Heat is thermal energy. It can be transferred from one place to another.
500
Why is the Change of State of Matter used?
Going through a phase. Adding energy to matter causes a physical change matter moves from one state to another.
500
Why do we use the Scientific Method?
The scientific method is a process for experimentation that is used to explore observations and answer questions. Even though we show the scientific method as a series of steps, scientist might miss a something and make their own mistake.
500
How do we use Newton's Laws of Motion?
If you use the same force to push a truck and push a car, the car will have more acceleration than the truck, because the car has less mass.
