CHAPTER 15

Heat and Electricity ………………………………………………………..558, 559

Lesson 1 How Is Thermal Energy Transferred? …………………………560-567
thermal energy: the kinetic energy of the moving particles of a substance or object
heat: the transfer of thermal energy from warmer objects to cooler ones
conduction: the transfer of thermal energy when two solid objects touch
convection: the transfer of thermal energy through the movement of a liquid or a gas
radiation: the transfer of thermal energy as waves
insulation: a substance that conducts thermal energy poorly
Lesson 2 What Is Electricity, and How Is It Produced? …………………568-577
static electricity: the electrical charge that builds up on an object that has gained or lost electrons
current electricity: the flow of electrons through a wire
Lesson 3 What Is a Circuit? ………………………………………………...578-585
circuit: a continuous path through which electrons flow
series circuit: a circuit in which there is only one path for the current to flow
parallel circuit: a circuit in which there is more than one path for the current to flow
electromagnet: a temporary magnet that is made by passing an electric current through a coil of wire that surrounds an iron core

CHAPTER 16

Forces and Motion ……………………………………………………….594, 595

Lesson 1 How Do Forces Affect Us? …………………………………..596-603
velocity: the speed and direction of a moving object
force: a push or a pull
acceleration: a change in velocity divided by the time it takes for that change to occur
inertia: the tendency of matter to resist a change in its state of motion
Lesson 2 How Do Forces Interact? …………………………………….604-611
balanced forces: equal forces that act in opposite directions and cancel one another out
unbalanced forces: forces that do not cancel one another out
friction: a force that acts between any two surfaces in contact with one another by preventing or slowing motion
Lesson 3 What Is Gravitational Force? ………………………………...612-619
gravitational force: the force that acts between any two masses in the universe and pulls them toward one another
weight: the measurement of the force of gravity on an object

CHAPTER 17

Work and Simple Machines …………………………………………….626, 627

Lesson 1 How Do Levers Help You Do Work? ………………………..628-637
work: that which is done on an object when a force causes the object to move in the direction of the force
lever: an arm or rod that turns around a fixed point
fulcrum: the fixed point that the effort arm of a lever moves around
pulley: a grooved wheel that has a rope or a chain around it
wheel and axle: a large wheel and a small wheel that turn together
Lesson 2 What Are Inclined Planes? …………………………………..638-645
inclined plane: any flat, sloping surface
wedge: a simple machine made up of two inclined planes placed back to back
screw: an inclined plane wrapped around a cylinder or a cone
