The five senses (seeing, smelling, touching, hearing, and tasting)
100
property of matter responsible for both electrostatic forces and electricity
What is charge
100
contrast between conductors and insulators
What is conductors let the current pass easily, insulators are poor conductors of electricity
100
the best way to do well on this test
use your study guide as flash cards and find a study partner
100
the Earth's magnetic North pole compared to it's geographic North
What is opposite (it faces Antarctica)
200
The first step and the main tools to include in the design step "develop possible solutions"
What is Brainstorming and applying the STEM principals
200
type of force when water is attracted to a charged particle such as a plastic comb that has just been used.
What is electrostatic
200
metals and electrolytes
What are two types of material that are good conductors of electricity
200
when domains align themselves along the magnetic field lines of a nearby magnet
What is when magnetic properties in the few materials that can become magnetic
200
opposite poles would show a force from one to the other
What is the attraction of two magnets to each other
300
The main consideration when writing the design problem
What is "it must be written so it can be tested"
300
One conducts electricity poorly, the other slows the electricity but still conducts.
What is the difference between insulator and resistor
300
what is attracted to the negative side of two oppositely charged parallel plates as it enters their electric field
What is a positively charged particle
300
what would happen if you turned a magnet around that was being repelled at a distance of 10 centimeters
What is it would be attracted at the same distance of 10 cm
300
this keeps a motor rotating
What is the poles in the coil are switched, causing the like poles to repel
400
the independent variable
What is the part of the experiment that is being tested. It is controlled by the scientist
400
charges that are not moving vs. flowing charges
What is the difference between static electricity and current electricity
400
This is similar to a voltage difference that supplies energy to make charges flow, (using water)
What is water pressure is higher at one end than the other so it flows.
400
when a magnet is dropped through a loop of wire an electric current can be detected
What is electromagnetic induction
400
reversing the direction of the current flow in an electromagnet
What is the north and south poles are reversed in an electromagnet
500
Design Process
What is a systematic problem-solving strategy, with criteria and constraints, used to develop possible solutions
500
the charge distribution on a neutral ball when placed next to a negatively charged ball
What is the positive charges within the neutral ball would move toward the negatively charged ball and the negative charges would move away from negatively charged ball.
500
the reason an inflated balloon sticks to the wall after rubbing it against your hair
What is excess charge builds up on the balloon and electrostatic forces allow the balloon and wall to be attracted to one another
500
coil the wire and run an electric current through the wire
What is change a straight piece of wire into an electromagnet
500
three ways to increase the strength of an electromagnet
What is 1) increase the number of coils
2) increase the current
3) add iron the the core
