How to Science
This is the approach to seeking knowledge that involves forming and testing a hypothesis in a logical, systematic way.

In an experiment, this is what you keep the same.
What is the controlled variable?

This is the rate at which velocity changes
What is acceleration?
A joule is the unit for this.
What is work? (and energy)
Because of his discoveries, we know the universe is expanding.
Who is Hubble?
This Law states:
An object in motion will stay in motion and an object at rest will stay ay rest unless an unbalanced force is applied.
What is Newton’s 1st Law of Motion?
This machine is used to lessen friction.
What is a wheel and axle?
What is observation?
Moving away from the sun, this is the order of the planets in our solar system.
What is
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune?
This is the unit of measure for a push or a pull on an object.
What is a newton?
The rate of work is given as this.
What is power?
Eureka! Legend says he ran naked through the streets out of excitement over his newfound ability to determine the volume of an irregularly-shaped solid.
Who is Archimedes?
This Principle states:
A change in pressure at any point in a fluid is transmitted equally and unchanged in all directions throughout the fluid
What is Pascal’s Principle?
This machine is a device that pivots around a fulcrum to change the mechanical advantage.
What is a lever?
1 mL is equal to this many liters.
What is 1/1000 or .001 liter.
A natural resource that is easily and quickly replenished is known as this.
What is a renewable resource?
This force opposes the motion of objects that touch as they move past each other.
What is friction?
This force is the reason why no machine is 100% efficient.
What is friction?
His Principle explains the concept of lift.
Who is Bernoulli?
This Law states:
Every action has an equal and opposite reaction.
What is Newton’s 3rd Law of Motion?
This machine lifts items by advancing up a slope.
What is an inclined plane?
In order for this to be considered, it must be possible to be tested and accepted or tested and rejected.
What is a hypothesis?
This is the study of planet Earth, including its composition.
What is geology?
This force acts between any two masses.
What is gravity?
These are the six types of simple machines.
What are wheel and axle, screw, wedge, inclined plane, pulley, and lever?
His name represents the unit for pressure.
Who is Pascal?
This Law states:
Energy can neither be created nor destroyed - only converted from one form of energy to another.
What is the Law of Conservation of Energy?
This machine can be used to raise or hold objects together.
What is a screw?
This tells WHAT happens, a fact.
This tells WHY it happens, an explanation.
What is a Scientific Law and a Scientific Theory?
These are the three main categories of rocks.
What are igneous, sedimentary, and metamorphic?
This is the unit used to describe a force distributed over an area, or pressure.
What is a pascal?
This is the ability to do work.
What is energy?
The SI unit named for him is also known as a newton-meter.
Who is James Prescott Joule?
This law states:
The rate of change in momentum is proportional to the force applied.
What is Newton's 2nd Law?
This machine alters a force’s direction.
What is a pulley?
This is why science is never settled.
What is
1- It presumes science exists in a binary state - that science isn't settled until it crosses some imaginary line after which it's finally settled. On the contrary, science by its very nature is never 100% settled.
2- It presumes that poor understanding in one area of science invalidates good understanding in other areas. This is not the case.
3. Natural Science is not about absolute proofs. It never reaches 100% certainty. This is the domain of the formal sciences, mathematics and logic. Science is improving our understanding by narrowing uncertainty. Different areas of science are and likely always will be understood with varying degrees of confidence.
This law states that the oldest rocks are at the bottom.
What is The Law of Superposition?
Buoyancy acts against this force.
What is gravity?
Forces acting in this way are added together.
What is the same direction?
The SI unit for power is named for this man.
Who is Watt?
This law states:
Absolute zero cannot be reached.
What is the 3rd Law of Thermodynamics?
When discussing levers, this can be substituted for the term "input force."
What is effort?
This is a way of expressing a value as the product of a number between 1 and 10 and a power of 10.
What is scientific notation?
This is the curving effect that Earth’s rotation has on all free-flowing objects.
What is the Coriolis effect?
This is the ratio of the distance an object moves to the amount of time the object moves.
What is speed?
Einstein’s E=mc2, says that energy and this are proportional & and can be converted into each other.
What is mass?
He developed his heliocentric astronomical model in 1543.
Who was Nicolaus Copernicus?
This Law States:
Energy can flow from colder objects to hotter objects only if work is done on the system.
What is the 2nd Law of Thermodynamics?
These are the three ways a machine can change a force.
What are
change the size of the force,
change the direction of a force, or
change the distance over which a force acts?
This is the gauge of how exact a measurement is.
What is precision?
This is where most of Earth's fresh water can be found.
What are glaciers?
This is the term for the direction from the
starting point and the length of the straight line
from the starting point to the ending point.
What is displacement?
Work is equal to the product of these two things?
What are force and distance?
In 1912, he hypothesized that the continents were once joined in a single supercontinent, which then broke into pieces that moved apart
Who is Alfred Wegener?
This Law States:
If two thermodynamic systems are each in thermal equilibrium with a third one, then they are in thermal equilibrium with each other.
What is the 0th Law of Thermodynamics?
This is the number of times a machine increases an input force.
What is mechanical advantage?
